Question

这里我使用httpclient从webservice获取响应，使用httppost我发送请求，服务器数据内容类型是application / x-www-form-urlencoded。

如何添加，这是我的代码，意味着我只需要“application / x-www-form-urlencoded”来自服务的此类数据

String postUrl = url;
        HttpClient client = new DefaultHttpClient(); 

        HttpPost request = new HttpPost(postUrl);


    request.setHeader("Content-type", "application/x-www-form-urlencoded");
    request.setHeader("Expect", "100-continue");

        HttpResponse response = client.execute(request);
        System.out.println("ddddddddddddddddddddddd  "+response);
        BufferedReader reader = new BufferedReader(
                new InputStreamReader(
                        response.getEntity().getContent(), "UTF-8"));
        String line;
        builder = new StringBuilder();
        while ((line = reader.readLine()) != null) {
            builder.append(line);
        }
        Log.d("Response", builder.toString());
        resObj = builder.toString();
        System.out.println("ddddddddddddddddddddddd  "+resObj);
    } catch (Exception e) {
        // TODO: handle exception
        Log.d("ERROR", e.toString());
    }

我尝试使用带有namepair值的httpost，它不起作用，所以使用其他方式得出结论

它的工作正常， 注意：我们需要java 1.7 jre

    String param1 = "9880938687";
    String param2 = "value2";
    // ... 
    List<NameValuePair> params = new ArrayList<NameValuePair>();
    params.add(new BasicNameValuePair("mobile", param1));
    String query = null;
    try {
        query = String.format("mobile=%s&param2=%s", 
             URLEncoder.encode(param1, charset), 
             URLEncoder.encode(param2, charset));
    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    URLConnection connection = new URL(targetURL).openConnection();
    connection.setDoOutput(true); // Triggers POST.
    connection.setRequestProperty("Accept-Charset", charset);
    connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded;charset=" + charset);

    try (OutputStream output = connection.getOutputStream()) {
        output.write(query.getBytes(charset));
    } 

    //InputStream response = connection.getInputStream();
    // ..
    //Get Response  
    InputStream is = connection.getInputStream();
    BufferedReader rd = new BufferedReader(new InputStreamReader(is));
    String line;
    StringBuffer response = new StringBuffer(); 
    while((line = rd.readLine()) != null) {
      response.append(line);
      response.append('\r');
    }
    rd.close();
    System.out.println("***"+response.toString());
    return response.toString();

如何使用httpclient为httppost添加内容类型？
