java - 在camel路由中发送POST请求

Question

我正在使用 Apache Camel 来实现 SOA 集成层。

但是当我尝试向外部 Web 服务发送 POST 请求时遇到一些问题。

这是我的 Camel 路线:

from("jetty:http://localhost:5000/plus_grand")
    .setHeader(Exchange.HTTP_METHOD , constant("POST"))
    .to("http://localhost/sub?bridgeEndpoint=false&throwExceptionOnFailure=false")

http://localhost/sub 是一个简单的 php 页面。本页打印请求信息。

代码是:

echo "<pre>";
    print_r($_SERVER);
echo "</pre>";

当我尝试运行它时，我得到以下结果:

Array
(
    [HTTP_HOST] => localhost
    [HTTP_USER_AGENT] => Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:47.0) Gecko/20100101 Firefox/47.0
    [HTTP_ACCEPT] => text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
    [HTTP_ACCEPT_LANGUAGE] => en-US,en;q=0.5
    [HTTP_ACCEPT_ENCODING] => gzip, deflate
    [HTTP_COOKIE] => csrftoken=rqcFAHftMkWsDEoLudTWIjPseAU7sJ40; oauth_consumer_key=136a3fd63028e1d157c6b939bcbe771c2dfe5710
    [HTTP_CONNECTION] => keep-alive
    [PATH] => /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
    [SERVER_SIGNATURE] =>

    [SERVER_SOFTWARE] => Apache/2.4.7 (Ubuntu)
    [SERVER_NAME] => localhost
    [SERVER_ADDR] => 127.0.0.1
    [SERVER_PORT] => 80
    [REMOTE_ADDR] => 127.0.0.1
    [DOCUMENT_ROOT] => /var/www/html
    [REQUEST_SCHEME] => http
    [CONTEXT_PREFIX] => 
    [CONTEXT_DOCUMENT_ROOT] => /var/www/html
    [SERVER_ADMIN] => webmaster@localhost
    [SCRIPT_FILENAME] => /var/www/html/sub/index.php
    [REMOTE_PORT] => 38604
    [GATEWAY_INTERFACE] => CGI/1.1
    [SERVER_PROTOCOL] => HTTP/1.1
    [REQUEST_METHOD] => GET
    [QUERY_STRING] => 
    [REQUEST_URI] => /sub/
    [SCRIPT_NAME] => /sub/index.php
    [PHP_SELF] => /sub/index.php
    [REQUEST_TIME_FLOAT] => 1480887502.957
    [REQUEST_TIME] => 1480887502
)

可以看到，请求方法是GET。

请问这是什么问题。

您的路由正在连接到基于 http v3.x 客户端库的旧版 http 组件。建议使用 http4://.. 作为端点。

然后使用每个示例的预定义常量:

from("direct:start")
.setHeader(Exchange.HTTP_METHOD,constant(org.apache.camel.component.http4.HttpMethods.POST))
  .to("http4://www.google.com")
