Apache Camel helps you integrate over 300 different systems!

URI format

http:hostname[:port][/resourceUri][?options]

Will by default use port 80 for HTTP and 443 for HTTPS.

Configuring Options

Camel components are configured on two separate levels:

component level
endpoint level

Configuring Component Options

The component level is the highest level which holds general and common configurations that are inherited by the endpoints. For example a component may have security settings, credentials for authentication, urls for network connection and so forth.

Some components only have a few options, and others may have many. Because components typically have pre configured defaults that are commonly used, then you may often only need to configure a few options on a component; or none at all.

Configuring components can be done with the Component DSL, in a configuration file (application.properties|yaml), or directly with Java code.

Configuring Endpoint Options

Where you find yourself configuring the most is on endpoints, as endpoints often have many options, which allows you to configure what you need the endpoint to do. The options are also categorized into whether the endpoint is used as consumer (from) or as a producer (to), or used for both.

Configuring endpoints is most often done directly in the endpoint URI as path and query parameters. You can also use the Endpoint DSL as a type safe way of configuring endpoints.

A good practice when configuring options is to use Property Placeholders, which allows to not hardcode urls, port numbers, sensitive information, and other settings. In other words placeholders allows to externalize the configuration from your code, and gives more flexibility and reuse.

The following two sections lists all the options, firstly for the component followed by the endpoint.

Component Options

The HTTP component supports 37 options, which are listed below.

Name	Description	Default	Type
cookieStore (producer)	To use a custom org.apache.http.client.CookieStore. By default the org.apache.http.impl.client.BasicCookieStore is used which is an in-memory only cookie store. Notice if bridgeEndpoint=true then the cookie store is forced to be a noop cookie store as cookie shouldn’t be stored as we are just bridging (eg acting as a proxy).		CookieStore
copyHeaders (producer)	If this option is true then IN exchange headers will be copied to OUT exchange headers according to copy strategy. Setting this to false, allows to only include the headers from the HTTP response (not propagating IN headers).	true	boolean
lazyStartProducer (producer)	Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.		boolean
responsePayloadStreamingThreshold (producer)	This threshold in bytes controls whether the response payload should be stored in memory as a byte array or be streaming based. Set this to -1 to always use streaming mode.	8192	int

authCachingDisabled (advanced)	Disables authentication scheme caching.		boolean
automaticRetriesDisabled (advanced)	Disables automatic request recovery and re-execution.		boolean
autowiredEnabled (advanced)	Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.	true	boolean

`Exchange.CONTENT_ENCODING`	`String`	The HTTP content encoding. Is set on both the IN and OUT message to provide a content encoding, such as `gzip`.

Exchange.HTTP_URI

String

URI to call. Will override existing URI set directly on the endpoint. This uri is the uri of the http server to call. Its not the same as the Camel endpoint uri, where you can configure endpoint options such as security etc. This header does not support that, its only the uri of the http server.

Exchange.HTTP_PATH

String

Request URI’s path, the header will be used to build the request URI with the HTTP_URI.

Exchange.HTTP_QUERY

String

URI parameters. Will override existing URI parameters set directly on the endpoint.

Exchange.HTTP_RESPONSE_CODE

int

The HTTP response code from the external server. Is 200 for OK.

Exchange.HTTP_RESPONSE_TEXT

String

The HTTP response text from the external server.

Exchange.HTTP_CHARACTER_ENCODING

String

Character encoding.

Exchange.CONTENT_TYPE

String

The HTTP content type. Is set on both the IN and OUT message to provide a content type, such as text/html.

Exchange.CONTENT_ENCODING

String

The HTTP content encoding. Is set on both the IN and OUT message to provide a content encoding, such as gzip.

Message Body

Camel will store the HTTP response from the external server on the OUT body. All headers from the IN message will be copied to the OUT message, so headers are preserved during routing. Additionally Camel will add the HTTP response headers as well to the OUT message headers.

Using System Properties

When setting useSystemProperties to true, the HTTP Client will look for the following System Properties and it will use it:

ssl.TrustManagerFactory.algorithm
javax.net.ssl.trustStoreType
javax.net.ssl.trustStore
javax.net.ssl.trustStoreProvider
javax.net.ssl.trustStorePassword
java.home
ssl.KeyManagerFactory.algorithm
javax.net.ssl.keyStoreType
javax.net.ssl.keyStore
javax.net.ssl.keyStoreProvider
javax.net.ssl.keyStorePassword
http.proxyHost
http.proxyPort
http.nonProxyHosts
http.keepAlive
http.maxConnections

Response code

Camel will handle according to the HTTP response code:

Response code is in the range 100..299, Camel regards it as a success response.
Response code is in the range 300..399, Camel regards it as a redirection response and will throw a HttpOperationFailedException with the information.
Response code is 400+, Camel regards it as an external server failure and will throw a HttpOperationFailedException with the information.

throwExceptionOnFailure The option, throwExceptionOnFailure, can be set to false to prevent the HttpOperationFailedException from being thrown for failed response codes. This allows you to get any response from the remote server.
There is a sample below demonstrating this.

Exceptions

HttpOperationFailedException exception contains the following information:

The HTTP status code
The HTTP status line (text of the status code)
Redirect location, if server returned a redirect
Response body as a java.lang.String, if server provided a body as response

Which HTTP method will be used

The following algorithm is used to determine what HTTP method should be used:
1. Use method provided as endpoint configuration (httpMethod).
2. Use method provided in header (Exchange.HTTP_METHOD).
3. GET if query string is provided in header.
4. GET if endpoint is configured with a query string.
5. POST if there is data to send (body is not null).
6. GET otherwise.

How to get access to HttpServletRequest and HttpServletResponse

You can get access to these two using the Camel type converter system using

You can get the request and response not just from the processor after the camel-jetty or camel-cxf endpoint.

HttpServletRequest request = exchange.getIn().getBody(HttpServletRequest.class);
HttpServletRequest response = exchange.getIn().getBody(HttpServletResponse.class);

Configuring URI to call

You can set the HTTP producer’s URI directly form the endpoint URI. In the route below, Camel will call out to the external server, oldhost, using HTTP.

from("direct:start")
        .to("http://oldhost");

And the equivalent Spring sample:

<camelContext xmlns="http://activemq.apache.org/camel/schema/spring">
  <route>
    <from uri="direct:start"/>
    <to uri="http://oldhost"/>
  </route>
</camelContext>

You can override the HTTP endpoint URI by adding a header with the key, Exchange.HTTP_URI, on the message.

from("direct:start")
  .setHeader(Exchange.HTTP_URI, constant("http://newhost"))
  .to("http://oldhost");

In the sample above Camel will call the http://newhost despite the endpoint is configured with http://oldhost.
If the http endpoint is working in bridge mode, it will ignore the message header of Exchange.HTTP_URI.

Configuring URI Parameters

The http producer supports URI parameters to be sent to the HTTP server. The URI parameters can either be set directly on the endpoint URI or as a header with the key Exchange.HTTP_QUERY on the message.

from("direct:start")
  .to("http://oldhost?order=123&detail=short");

Or options provided in a header:

from("direct:start")
  .setHeader(Exchange.HTTP_QUERY, constant("order=123&detail=short"))
  .to("http://oldhost");

How to set the http method (GET/PATCH/POST/PUT/DELETE/HEAD/OPTIONS/TRACE) to the HTTP producer

The HTTP component provides a way to set the HTTP request method by setting the message header. Here is an example:

from("direct:start")
  .setHeader(Exchange.HTTP_METHOD, constant(org.apache.camel.component.http.HttpMethods.POST))
  .to("http://www.google.com")
  .to("mock:results");

The method can be written a bit shorter using the string constants:

.setHeader("CamelHttpMethod", constant("POST"))

And the equivalent Spring sample:

<camelContext xmlns="http://activemq.apache.org/camel/schema/spring">
  <route>
    <from uri="direct:start"/>
    <setHeader name="CamelHttpMethod">
        <constant>POST</constant>
    </setHeader>
    <to uri="http://www.google.com"/>
    <to uri="mock:results"/>
  </route>
</camelContext>

Using client timeout - SO_TIMEOUT

See the HttpSOTimeoutTest unit test.

Configuring a Proxy

The HTTP component provides a way to configure a proxy.

from("direct:start")
  .to("http://oldhost?proxyAuthHost=www.myproxy.com&proxyAuthPort=80");

There is also support for proxy authentication via the proxyAuthUsername and proxyAuthPassword options.

Using proxy settings outside of URI

To avoid System properties conflicts, you can set proxy configuration only from the CamelContext or URI.
Java DSL :

 context.getGlobalOptions().put("http.proxyHost", "172.168.18.9");
 context.getGlobalOptions().put("http.proxyPort", "8080");

Spring XML

   <camelContext>
       <properties>
           <property key="http.proxyHost" value="172.168.18.9"/>
           <property key="http.proxyPort" value="8080"/>
      </properties>
   </camelContext>

Camel will first set the settings from Java System or CamelContext Properties and then the endpoint proxy options if provided.
So you can override the system properties with the endpoint options.

There is also a http.proxyScheme property you can set to explicit configure the scheme to use.

Configuring charset

If you are using POST to send data you can configure the charset using the Exchange property:

exchange.setProperty(Exchange.CHARSET_NAME, "ISO-8859-1");

Sample with scheduled poll

This sample polls the Google homepage every 10 seconds and write the page to the file message.html:

from("timer://foo?fixedRate=true&delay=0&period=10000")
  .to("http://www.google.com")
  .setHeader(FileComponent.HEADER_FILE_NAME, "message.html")
  .to("file:target/google");

URI Parameters from the endpoint URI

In this sample we have the complete URI endpoint that is just what you would have typed in a web browser. Multiple URI parameters can of course be set using the & character as separator, just as you would in the web browser. Camel does no tricks here.

// we query for Camel at the Google page
template.sendBody("http://www.google.com/search?q=Camel", null);

URI Parameters from the Message

Map headers = new HashMap();
headers.put(Exchange.HTTP_QUERY, "q=Camel&lr=lang_en");
// we query for Camel and English language at Google
template.sendBody("http://www.google.com/search", null, headers);

In the header value above notice that it should not be prefixed with ? and you can separate parameters as usual with the & char.

Getting the Response Code

You can get the HTTP response code from the HTTP component by getting the value from the Out message header with Exchange.HTTP_RESPONSE_CODE.

Exchange exchange = template.send("http://www.google.com/search", new Processor() {
  public void process(Exchange exchange) throws Exception {
    exchange.getIn().setHeader(Exchange.HTTP_QUERY, constant("hl=en&q=activemq"));
  }
});
Message out = exchange.getOut();
int responseCode = out.getHeader(Exchange.HTTP_RESPONSE_CODE, Integer.class);

Disabling Cookies

To disable cookies you can set the HTTP Client to ignore cookies by adding this URI option:
httpClient.cookieSpec=ignoreCookies

Basic auth with the streaming message body

In order to avoid the NonRepeatableRequestException, you need to do the Preemptive Basic Authentication by adding the option:
authenticationPreemptive=true

Advanced Usage

If you need more control over the HTTP producer you should use the HttpComponent where you can set various classes to give you custom behavior.

Setting up SSL for HTTP Client

Using the JSSE Configuration Utility

The HTTP component supports SSL/TLS configuration through the Camel JSSE Configuration Utility. This utility greatly decreases the amount of component specific code you need to write and is configurable at the endpoint and component levels. The following examples demonstrate how to use the utility with the HTTP component.

Programmatic configuration of the component

KeyStoreParameters ksp = new KeyStoreParameters();
ksp.setResource("/users/home/server/keystore.jks");
ksp.setPassword("keystorePassword");

KeyManagersParameters kmp = new KeyManagersParameters();
kmp.setKeyStore(ksp);
kmp.setKeyPassword("keyPassword");

SSLContextParameters scp = new SSLContextParameters();
scp.setKeyManagers(kmp);

HttpComponent httpComponent = getContext().getComponent("https", HttpComponent.class);
httpComponent.setSslContextParameters(scp);

Spring DSL based configuration of endpoint

  <camel:sslContextParameters
      id="sslContextParameters">
    <camel:keyManagers
        keyPassword="keyPassword">
      <camel:keyStore
          resource="/users/home/server/keystore.jks"
          password="keystorePassword"/>
    </camel:keyManagers>
  </camel:sslContextParameters>

  <to uri="https://127.0.0.1/mail/?sslContextParameters=#sslContextParameters"/>

Configuring Apache HTTP Client Directly

Basically camel-http component is built on the top of Apache HttpClient. Please refer to SSL/TLS customization for details or have a look into the org.apache.camel.component.http.HttpsServerTestSupport unit test base class.
You can also implement a custom org.apache.camel.component.http.HttpClientConfigurer to do some configuration on the http client if you need full control of it.

However if you just want to specify the keystore and truststore you can do this with Apache HTTP HttpClientConfigurer, for example:

KeyStore keystore = ...;
KeyStore truststore = ...;

SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("https", 443, new SSLSocketFactory(keystore, "mypassword", truststore)));

And then you need to create a class that implements HttpClientConfigurer, and registers https protocol providing a keystore or truststore per example above. Then, from your camel route builder class you can hook it up like so:

HttpComponent httpComponent = getContext().getComponent("http", HttpComponent.class);
httpComponent.setHttpClientConfigurer(new MyHttpClientConfigurer());

If you are doing this using the Spring DSL, you can specify your HttpClientConfigurer using the URI. For example:

<bean id="myHttpClientConfigurer"
 class="my.https.HttpClientConfigurer">
</bean>

<to uri="https://myhostname.com:443/myURL?httpClientConfigurer=myHttpClientConfigurer"/>

As long as you implement the HttpClientConfigurer and configure your keystore and truststore as described above, it will work fine.

Using HTTPS to authenticate gotchas

An end user reported that he had problem with authenticating with HTTPS. The problem was eventually resolved by providing a custom configured org.apache.http.protocol.HttpContext:

1. Create a (Spring) factory for HttpContexts:

public class HttpContextFactory {

  private String httpHost = "localhost";
  private String httpPort = 9001;

  private BasicHttpContext httpContext = new BasicHttpContext();
  private BasicAuthCache authCache = new BasicAuthCache();
  private BasicScheme basicAuth = new BasicScheme();

  public HttpContext getObject() {
    authCache.put(new HttpHost(httpHost, httpPort), basicAuth);

    httpContext.setAttribute(ClientContext.AUTH_CACHE, authCache);

    return httpContext;
  }

  // getter and setter
}

2. Declare an HttpContext in the Spring application context file:

<bean id="myHttpContext" factory-bean="httpContextFactory" factory-method="getObject"/>

3. Reference the context in the http URL:

<to uri="https://myhostname.com:443/myURL?httpContext=myHttpContext"/>

Using different SSLContextParameters

The HTTP component only support one instance of org.apache.camel.support.jsse.SSLContextParameters per component. If you need to use 2 or more different instances, then you need to setup multiple HTTP components as shown below. Where we have 2 components, each using their own instance of sslContextParameters property.

<bean id="http-foo" class="org.apache.camel.component.http.HttpComponent">
   <property name="sslContextParameters" ref="sslContextParams1"/>
   <property name="x509HostnameVerifier" ref="hostnameVerifier"/>
</bean>

<bean id="http-bar" class="org.apache.camel.component.http.HttpComponent">
   <property name="sslContextParameters" ref="sslContextParams2"/>
   <property name="x509HostnameVerifier" ref="hostnameVerifier"/>
</bean>

Spring Boot Auto-Configuration

When using http with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-http-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 38 options, which are listed below.
