Question

我正在寻找教程或快速示例，我如何发送POST数据抛出openStream。

我的代码是：

URL url = new URL("http://localhost:8080/test");
            InputStream response = url.openStream();
            BufferedReader reader = new BufferedReader(new InputStreamReader(response, "UTF-8"));

你能帮帮我吗？

Answer 1

    URL url = new URL(urlSpec);
    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    connection.setRequestMethod(method);
    connection.setDoOutput(true);
    connection.setDoInput(true);

    // important: get output stream before input stream
    OutputStream out = connection.getOutputStream();
    out.write(content);
    out.close();        

            // now you can get input stream and read.
    BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
    String line = null;

    while ((line = reader.readLine()) != null) {
        writer.println(line);
    }
