Question

尝试使用HTTPURLCOnnection进行发布操作，但无法获得正确的响应。邮递员也一样。下面的代码：

        URL url = new URL("<url>");
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setRequestProperty("Cookie", "value");

        connection.setDoOutput(true);
        connection.setDoInput(true);
        connection.setRequestMethod("POST");

        // send JSON Message to dataiku server
        String body = "{ 'login':'" + "<id>" + "','password':'" + "<pswd>"
                + "'" + "}";
        log.info("Payload: " + body);
        OutputStreamWriter outputStreamWriter = new OutputStreamWriter(connection.getOutputStream());
        outputStreamWriter.write(body);
        outputStreamWriter.flush();

        BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));

错误：

java.io.IOException：服务器为URL返回HTTP响应代码：400 在sun.net.www.protocol.http.HttpURLConnection.getInputStream0（HttpURLConnection.java:1894）在sun.net.www.protocol.http.HttpURLConnection.getInputStream（HttpURLConnection.java:1492）在sun.reflect.NativeMethodAccessorImpl.invoke0（本机方法）处在sun.reflect.NativeMethodAccessorImpl.invoke（NativeMethodAccessorImpl.java:62）在sun.reflect.DelegatingMethodAccessorImpl.invoke（DelegatingMethodAccessorImpl.java:43）在java.lang.reflect.Method.invoke（Method.java:498）在com.intellij.rt.execution.CommandLineWrapper.main（CommandLineWrapper.java:65）

任何人都可以帮助解决上面的代码出什么问题吗？

使用POST时HTTPUrlConnection给出400错误
