使用骆驼流从POST输出到URL [英] Using Camel to stream output from a POST to a URL

问题描述

是否有可能使用骆驼流组件读取POST的输出到一个URL？喜欢的东西：＆LT;到URI =流：URL URL = HTTP：//本地主机：8080 / mycontext / myservlet/＆GT;
我试过，但没有奏效。我需要张贴JSON对象到一个URL和处理返回一个巨大的有效载荷，所以我需要它被传输到一个文件，而无需首先加载它全部在内存中。是否有骆驼DSL的替代品或者我应该以某种方式使用一个bean，例如使用HttpURLConnection类，做流？

Is it possible to use the Camel Stream Component to read output of a POST to a URL? Something like: <to uri="stream:url?url=http://localhost:8080/mycontext/myservlet"/> I tried this but it did not work. I need to post a JSON object to a URL and process a huge payload being returned, so I need it to be streamed to a file without loading it all in memory first. Are there alternatives in the CAMEL DSLs or should I be using a bean somehow, e.g. using a HttpUrlConnection, to do the streaming?

推荐答案

只需使用 HTTP模块 - 它支持POST请求，进而会给你一个的InputStream 的回报

Simply use the http module - it does support POST requests and furthermore will give you an InputStream in return.

只要你的路线并不强制骆驼自动将邮件转换为有效载荷字符串，你可以自由地实现你的处理器的任何专有流逻辑。换句话说，请确保您的处理器，例如bean方法，使用的InputStream ，而不是字符串在其方法签名。

As long as your route does not force Camel to auto-convert the message payload to String, you are free to implement any proprietary streaming logic in your handler. In other words, make sure your handler, e.g. a bean method, uses InputStream rather than String in its method signature.
