我有一个服务器接收POST请求并使用数据流回答。我在 URL 上看到过，我可以打开连接或流。但是，流没有写出数据的方法：

I have a server that takes a POST request and answers with a data stream. I have seen that on URL I can open a connection or a stream. A stream, however, has no method for writing out data:

URL url = new URL("..."); url.openConnection(); //either I open a connection which has a output stream, but no input url.openStream(); //or I open a stream, but I cannot write anything out

如何优雅地解决这个问题？

How can I solve this problem elegantly?

推荐答案

使用OutputStream的示例代码段。

Sample code snippet to use OutputStream.

注意：您可以设置内容类型&仅将URL参数发送到URL。

Note: You can set content types & send some URL parameters to the URL only.

URL obj = new URL(url);//some url HttpURLConnection con = (HttpURLConnection) obj.openConnection(); con.setDoOutput(true); DataOutputStream wr = new DataOutputStream(con.getOutputStream()); String urlParams = "fName=xyz&lname=ABC&pin=12345"; // some parameters wr.writeBytes(urlParams); wr.flush(); wr.close();
