http delete 方法传参数遇到java.net.ProtocolException: DELETE does not support writing的问题

最近在测试通过http delete method传参数调用服务端方法，遇到了java.net.ProtocolException: DELETE does not support writing

			try {
				url = new URL(path);
				HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
				httpCon.setDoOutput(true);
				httpCon.setRequestMethod(method);
				OutputStreamWriter out = new OutputStreamWriter(
						httpCon.getOutputStream());
				out.write(new Gson().toJson(params));
				out.close();
				String urlStringsss = convertStreamToString(httpCon.getInputStream());
				InfoPrinter.printLog(convertStreamToString(httpCon.getInputStream()));
			} catch (MalformedURLException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}

　　执行时捕捉到

java.net.ProtocolException: DELETE does not support writing

后来在万能的google帮助下，最终在stackoverflow上找到了答案，先来看国外的一位Coder怎么说

I do not believe that HTTP DELETE takes input - I believe it acts like a GET variant.

The implementation provided by HTTP Client seems to support this conjecture as well.

If you are looking to provide a delete with a body, you /might/ want to consider using a POST to a location that accepts a body.

But in answer to your question, no, delete does not accept a body. You can add query parameters but not a body.

HTTP DELETE 不支持通过output来write参数，只能像GET方法一样通过url paramter来传递参数，否则会报标题上遇到的错误。
