如何在Netty中发送带有POST参数的请求? [英] How to send a request with POST parameters in Netty?

问题描述

我正在尝试在Netty中发送带有POST参数的请求.

I'm trying to send a request with POST parameters in Netty.

我搜索了Netty API，Google和此处(堆栈溢出)

I searched Netty API, Google, and here (Stack Overflow)

但是没有找到任何好的方法. (这可能是我搜索技巧糟糕的错误:'(如果是，我表示歉意)

but didn't find any good way to do it. (It could be my fault of terrible searching skill :'( If so, I apologize)

有没有可以轻松实现的API?

Is there any API to do it easily?

还是我必须对所有参数进行编码并由我自己在内容中进行设置?

Or do I have to do it by encoding all parameters and setting it in the content by myself?

请让我知道执行此操作的任何好方法.

Please let me know any good way to do it.

推荐答案

下面是一个如何上传文件的示例:

Here's an example of how you would do a file upload:

https ://github.com/netty/netty/tree/master/example/src/main/java/io/netty/example/http/upload

如果您不想上传文件，只需忽略MIME multipart位.

If you don't want to upload a file, just ignore the MIME multipart bit.

尝试类似的东西:

HttpRequest httpReq=new DefaultHttpRequest(HttpVersion.HTTP_1_1,HttpMethod.POST,uri);
httpReq.setHeader(HttpHeaders.Names.HOST,host);
httpReq.setHeader(HttpHeaders.Names.CONNECTION,HttpHeaders.Values.KEEP_ALIVE);
httpReq.setHeader(HttpHeaders.Names.ACCEPT_ENCODING,HttpHeaders.Values.GZIP);
httpReq.setHeader(HttpHeaders.Names.CONTENT_TYPE,"application/x-www-form-urlencoded");     
String params="a=b&c=d";
ChannelBuffer cb=ChannelBuffers.copiedBuffer(params,Charset.defaultCharset());
httpReq.setHeader(HttpHeaders.Names.CONTENT_LENGTH,cb.readableBytes());
httpReq.setContent(cb);

请参见发送POST Netty的参数，为什么发行版中不没有DefaultHttpDataFactory?
