我主要在javascript中使用ajax命令，并希望在android java中创建这些命令。（API 22+）

Ajax代码：

 $.ajax({
     url: 'http://myurl/app_login.php',
     dataType: 'jsonp',
     data: {email:myEmail, password:myPassword}, 
     success: function(data)    {
         callback(data);
     },
     error: function(data)  {
         callback(data);
     }    
 })

我过去常做的事：

final boolean myfunction(String user){
    HttpClient client = new DefaultHttpClient();
    HttpPost post = new HttpPost(getString(R.string.authorization_url));
    String body;
    body = "email=" + user;

    post.setHeader("Content-type","application/x-www-form-urlencoded");

    try {
        post.setEntity(new StringEntity(body,"UTF-8"));
        try {
            HttpResponse response = client.execute(post);
            BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
            String json = reader.readLine();
            try {
                JSONObject finalResult = new JSONObject(json);

                //do stuff with final result

                return finalResult.getBoolean("success");
            } catch (JSONException e1) {
                e1.printStackTrace();
            }
        } catch (ClientProtocolException e) {
            e.printStackTrace();
            return false;
        } catch (IOException e) {
            e.printStackTrace();
            return false;
        }
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }
    return false;
}

上述代码的相关进口：

import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.io.UnsupportedEncodingException;
    import org.apache.http.HttpResponse;
    import org.apache.http.client.ClientProtocolException;
    import org.apache.http.client.HttpClient;
    import org.apache.http.client.methods.HttpPost;
    import org.apache.http.entity.StringEntity;
    import org.apache.http.impl.client.DefaultHttpClient;
    import org.json.JSONException;
    import org.json.JSONObject;

奖金问题寻求答案：如果有人能告诉我，既然我上传了一个文件，我会非常感激，就像我在下面做的那样。遗憾的是，这些方法/函数中有很多现在已经被弃用了。这与上面的问题类似，但我会上传一个文件，然后等待

try{}

的

finally（）
