Android仿人人客户端（v5.7.1）——通过HTTPS协议的POST方式获取用户的基本信息

一、扩展之前的网络模块

基于Android仿人人客户端（v5.7.1）——网络模块处理的架构这篇进行扩展，添加通过HTTPS协议的POST方式访问网络的处理。自定义类（AsyncHttpsPost）让其继承AsyncBaseRequest类，代码如下：

[java]
package com.everyone.android.net;

import java.io.IOException;
import java.io.InputStream;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;

import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.protocol.HTTP;

import com.everyone.android.callback.ParseCallback;
import com.everyone.android.callback.ResultCallback;

/**
* 功能描述：通过HTTPS协议发送POST网络请求
* @author android_ls
*
*/
public class AsyncHttpsPost extends AsyncBaseRequest {

    /**
     *
     */
    private static final long serialVersionUID = 4L;

    public AsyncHttpsPost(String url, Map<String, String> parameter,
            ParseCallback handler, ResultCallback requestCallback) {
        super(url, parameter, handler, requestCallback);
    }

    @Override
    protected InputStream getRequestResult() throws IOException {
        List<NameValuePair> paramPairs = new ArrayList<NameValuePair>();
        if(parameter != null && !parameter.isEmpty()){
            for(Map.Entry<String, String> entry : parameter.entrySet()){
                paramPairs.add(new BasicNameValuePair(entry.getKey(), entry.getValue()));
            }
        }

        UrlEncodedFormEntity entitydata = new UrlEncodedFormEntity(paramPairs, HTTP.UTF_8);
        HttpPost post = new HttpPost(requestUrl);
        post.setEntity(entitydata);
        DefaultHttpClient client = new DefaultHttpClient();
        // 执行POST方式请求
        HttpResponse response = client.execute(post);
        if(response.getStatusLine().getStatusCode()==200){
            return response.getEntity().getContent();
        }

        return null;
    }

}

package com.everyone.android.net;

import java.io.IOException;
import java.io.InputStream;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;

import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.protocol.HTTP;

import com.everyone.android.callback.ParseCallback;
import com.everyone.android.callback.ResultCallback;

/**
* 功能描述：通过HTTPS协议发送POST网络请求
* @author android_ls
*
*/
public class AsyncHttpsPost extends AsyncBaseRequest {

/**
*
*/
private static final long serialVersionUID = 4L;

public AsyncHttpsPost(String url, Map<String, String> parameter,
ParseCallback handler, ResultCallback requestCallback) {
super(url, parameter, handler, requestCallback);
}

@Override
protected InputStream getRequestResult() throws IOException {
     List<NameValuePair> paramPairs = new ArrayList<NameValuePair>();
        if(parameter != null && !parameter.isEmpty()){
            for(Map.Entry<String, String> entry : parameter.entrySet()){
                paramPairs.add(new BasicNameValuePair(entry.getKey(), entry.getValue()));
            }
        }

        UrlEncodedFormEntity entitydata = new UrlEncodedFormEntity(paramPairs, HTTP.UTF_8);
        HttpPost post = new HttpPost(requestUrl);
        post.setEntity(entitydata);
        DefaultHttpClient client = new DefaultHttpClient();
        // 执行POST方式请求
        HttpResponse response = client.execute(post);
        if(response.getStatusLine().getStatusCode()==200){
            return response.getEntity().getContent();
        }

  return null;
}

}
二、获取用户的基本信息

向服务器端发送请求，获取用户的基本信息。注：为什么要使用HTTPS协议发送请求？官方给出的理由，使用HTTPS协议调用API接口可以免去SIG认证。

1、获取用户信息所需的参数

[java]
String url = "https://api.renren.com/restserver.do";
Map<String, String> parameter = new HashMap<String, String>();
parameter.put("v", "1.0"); // API的版本号，固定值为1.0
parameter.put("access_token", accessToken); // OAuth2.0验证授权后获得的token。
parameter.put("format", "JSON"); // 返回值的格式。请指定为JSON或者XML，推荐使用JSON，缺省值为XML
parameter.put("call_id", "1.0"); // 请求队列号
parameter.put("method", "users.getInfo"); // 你要访问那个接口，我们肯定调用获取用户的信息的接口咯，该接口支持批量获取。

String url = "https://api.renren.com/re
