我需要通过发布请求来验证用户。我正在使用 REST 协议发布我的 xml 数据，但出现 403 错误。请帮助我找出我做错了什么，下面是我要发布的代码。

public void makePostConnection(String fileUrl,
            HashMap<String, String> requestData) {
        URL url;
        HttpURLConnection urlConnection;
        try {
            url = new URL(fileUrl);
            urlConnection = (HttpURLConnection) url.openConnection();
            urlConnection.setRequestMethod("POST");
            urlConnection.setRequestProperty("Content-Type",
                    "application/x-www-form-urlencoded");
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost(fileUrl);
            httppost.addHeader("accept", "text/xml");
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(
                    requestData.size());
            System.out.println("Size= " + requestData.size());

            for (Entry<String, String> entry : requestData.entrySet()) {
                nameValuePairs.add(new BasicNameValuePair(entry.getKey(), entry
                        .getValue()));
                System.out.println("Key= " + entry.getKey() + " Value= "
                        + entry.getValue());
            }
            System.out.println("Request ba= " + nameValuePairs.toString());
            StringEntity requestBody = new StringEntity(
                    nameValuePairs.toString());
            // requestBody.setContentType("text/xml");
            // httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            httppost.setEntity(requestBody);
            // httppost.set
            // Execute HTTP Post Request
            HttpResponse response = httpclient.execute(httppost);
            int code = response.getStatusLine().getStatusCode();

            System.out.println("Code= " + code);

        } catch (MalformedURLException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
    }

嗨，我通过更改我设置的某些行来解决我的问题 httppost.addHeader("Content-Type","application/x-www-form-urlencoded"); 并通过执行此 UrlEncodedFormEntity ent = new UrlEncodedFormEntity(nameValuePairs,HTTP.UTF_8); 来发出 urlencoded 请求 以下是我提出成功请求的所有代码。

try {
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost(fileUrl);
            httppost.addHeader("Content-Type",
                    "application/x-www-form-urlencoded");
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(
                    requestData.size());
            System.out.println("Size= " + requestData.size());

            for (Entry<String, String> entry : requestData.entrySet()) {
                nameValuePairs.add(new BasicNameValuePair(entry.getKey(), entry
                        .getValue()));
                System.out.println("Key= " + entry.getKey() + " Value= "
                        + entry.getValue());
            }

            UrlEncodedFormEntity ent = new UrlEncodedFormEntity(nameValuePairs,
                    HTTP.UTF_8);
            httppost.setEntity(ent);
            HttpResponse response = httpclient.execute(httppost);
            int code = response.getStatusLine().getStatusCode();

            System.out.println("Code= " + code);

        } catch (MalformedURLException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
    }
