Question

我需要使用参数创建HTTP POST请求。我知道有很多例子，我尝试过使用HTTPparams，NameValuePair等，但似乎无法获得服务器的正确格式。

Server Type: REST based API utilizing JSON for data transfer Content-type: application/json Accept: application/json Content-length: 47 {"username":"abcd","password":"1234"}

我可以传递这些标题，但我似乎无法通过这些参数“用户名”，“密码”。这是我的代码：

    HttpClient client = new DefaultHttpClient();  
    HttpPost post = new HttpPost("http://www.mymi5.net/API/auth/login");   
    List<NameValuePair> pairs = new ArrayList<NameValuePair>();  
    pairs.add(new BasicNameValuePair("username","abcd"));  
    pairs.add(new BasicNameValuePair("password","1234"));  
    post.setHeader("Content-type", "application/json");
    post.setHeader("Accept", "application/json");
    UrlEncodedFormEntity entity = new UrlEncodedFormEntity(pairs,"UTF-8");  
    post.setEntity(entity);  
    HttpResponse response = client.execute(post);

我试图调试，但无法确定实体是否正确连接......我做错了什么？

先谢谢。玛斯

试试这个：

HttpClient client = new DefaultHttpClient();  
    HttpPost post = new HttpPost("http://www.mymi5.net/API/auth/login");   
    post.setHeader("Content-type", "application/json");
    post.setHeader("Accept", "application/json");
JSONObject obj = new JSONObject();
obj.put("username", "abcd");
obj.put("password", "1234");
    post.setEntity(new StringEntity(obj.toString(), "UTF-8"));
    HttpResponse response = client.execute(post);

我不太确定，根据您的描述，但似乎您的服务器需要一个JSON内容对象而不是URL中编码的数据。发送这样的内容作为帖子的正文：

{"username":"abcd","password":"1234"}

Answer 3

HttpClient client = new DefaultHttpClient();  
HttpPost post = new HttpPost("http://www.mymi5.net/API/auth/login");   
List<NameValuePair> pairs = new ArrayList<NameValuePair>();  

pairs.add(new BasicNameValuePair("username","abcd"));  
pairs.add(new BasicNameValuePair("password","1234"));  

UrlEncodedFormEntity entity = new UrlEncodedFormEntity(pairs,HTTP.UTF_8);  
post.setEntity(entity);  
HttpResponse response = client.execute(post);

试试这个因为当我尝试HTTP发布时，它对我来说非常适合。

这可能适合你。

假设您已经拥有了json对象。

注意：（1）在服务器中，您需要以utf-8（也在数据库中）处理请求。

    @SuppressWarnings("unchecked")
private static HttpResponse executePostRequest(JSONObject jsonData, String url) {
    DefaultHttpClient httpclient = new DefaultHttpClient();
    HttpPost httpost = new HttpPost(url);

    try {
        httpost.setEntity(new ByteArrayEntity(jsonData.toString().getBytes("UTF8")));
        httpost.setHeader("Accept", "application/json");
        httpost.setHeader("Content-type", "application/json;charset=UTF-8");
        httpost.setHeader("Accept-Charset", "utf-8");
        HttpResponse httpResponse = httpclient.execute(httpost);
        return httpResponse;

    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return null;
}

然后在客户端处理服务器响应，如下所示：

String responseBody = EntityUtils
                    .toString(response.getEntity(), "UTF-8");

Android：Http帖子，参数不起作用
