HttpURLConnection 方法总是 GET？

Question

如 Android 文档所示，我已设置 setDoOutPut(true); 以便连接发送为 POST。但是，在调试器中，当我检查 HTTPURLConnection 方法成员时，它总是 GET，即使在 setDoOutput(true) 之后甚至 setRequestMethod("POST")。我是否以某种方式将其重置回 GET？

URL url = new URL(serverAddr);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setDoOutput(true);
urlConnection.setRequestMethod(verb);
urlConnection.setFixedLengthStreamingMode(postBody.getBytes().length);
//urlConnection.setRequestProperty("Content-Length", postBody.getBytes().toString());
urlConnection.setRequestProperty("Content-Type", "application/json;charset=utf-8");

urlConnection.connect();

OutputStream out = new BufferedOutputStream(urlConnection.getOutputStream());
out.write(postBody.getBytes());
out.flush();

int responseCode = urlConnection.getResponseCode();
System.out.println("HTTPS RESPONSE CODE: " + responseCode);

out.close();

编辑：这一定是个错误...调试器清楚地显示 setDoOuput 成员变量为 false，即使我将其设置为 true。未设置！

如果您希望使用 POST 动词并随请求发送数据，则需要使用 urlConnection.setDoInput(true);。

http://developer.android.com/reference/java/net/URLConnection.html#setDoInput(boolean)

必须在建立连接前设置。

这是我的工作示例：

    url = new URL(requestURL);

    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    conn.setReadTimeout(15000);
    conn.setConnectTimeout(15000);
    conn.setRequestMethod("POST");
    conn.setDoInput(true);
    conn.setDoOutput(true);


    OutputStream os = conn.getOutputStream();
    BufferedWriter writer = new BufferedWriter(
            new OutputStreamWriter(os, "UTF-8"));
    writer.write(getPostDataString(postDataParams));

    writer.flush();
    writer.close();
    os.close();
    int responseCode=conn.getResponseCode();
    Map<String, List<String>> mp = conn.getHeaderFields();

    if (responseCode == HttpsURLConnection.HTTP_OK) {
        String line;
        BufferedReader br=new BufferedReader(new InputStreamReader(conn.getInputStream()));
        while ((line=br.readLine()) != null) {
            response+=line;
        }
    }

HttpURLConnection 方法总是 GET？

HttpURLConnection method is always GET?
