【问题标题】:Get Http Response headers and Request headers in Android在 Android 中获取 Http 响应标头和请求标头

【问题描述】:

我将查询字符串发布到 url,现在我想获取请求标头并使用其中一个键。我编写了一个可以获取响应标头但不能获取请求标头的代码。到目前为止,这是我的代码:

URL url = null;
        try {
            url = new URL(getString(R.string.auth_url));
            HttpURLConnection con = (HttpURLConnection) url.openConnection();
            con.setReadTimeout(10000);
            con.setConnectTimeout(15000);
            con.setRequestMethod("POST");
            con.setDoOutput(true);
            con.setDoInput(true);
            String urlParameters  = "username="+ URLEncoder.encode(params[0], "UTF-8")+"&password="+URLEncoder.encode(params[1], "UTF-8")+"&captcha=1234";
            con.setRequestProperty( "charset", "utf-8");
            OutputStream os = con.getOutputStream();
            BufferedWriter writer = new BufferedWriter(
                    new OutputStreamWriter(os, "UTF-8"));
            writer.write(urlParameters);
            writer.flush();
            writer.close();
            os.close();

            BufferedReader reader = new BufferedReader(new InputStreamReader(con.getInputStream()));

            StringBuilder stringBuilder = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                stringBuilder.append(line);
            }

            Log.i("body", "input = " + stringBuilder.toString());
            reader.close();

            return con.getHeaderFields().toString();

            } catch (MalformedURLException e) {
            e.printStackTrace();
            return null;
        } catch (IOException e) {
            e.printStackTrace();
            return null;

return con.getHeaderFields().toString() 行给了我整个响应头。现在我应该如何更改此代码以获取 请求标头?!

提示:我使用了 AsyncTask,以上几行在我的 doInBackground 方法中。

    【解决方案1】:

    尝试使用:

    1)getRequestProperties()API 接收所有请求头列表

    2)getRequestProperty(String field)API 接收字段名对应的header。
