网络模块的处理，基本上已讲解完，后面若遇到其他的网络处理需求再调整。这篇接着仿人人客户端（v5.7.1）——人人授权访问界面 继续，前面聊到打开人人授权界面，当用户输入访问人人的账号和密码，点击“登录”按钮后，若成功服务器端会返回accessToken。之后怎么处理，下面开始这篇的讲述：

一、对服务器端返回的accessToken进行处理

服务器端会返回accessToken

195789%7C6.7faefec2274182195287028d00323781.2592000.1367118000-461345584

通过运行人人官方提供的Demo，打印LOG如下：

195789|6.7faefec2274182195287028d00323781.2592000.1367118000-461345584

需要做的处理：

accessToken = accessToken.replace("%7C", "|");

二、用accessToken通过HTTP协议POST方式交换session_key、session_secret和userId。

1、发起网络请求

Map<String, String> parameter = new HashMap<String, String>();
parameter.put("oauth_token", accessToken);
AsyncBaseRequest asyncRequest = new AsyncHttpPost(Constant.SESSION_KEY_URL, parameter,
new ParseCallback (){

@Override
public Boolean parse(String json) throws JSONException {
Log.e(TAG, "result = " + json);

return false;
}

},
new  ResultCallback(){

@Override
public void onSuccess(final Object result) {
mHandler.post(new Runnable() {

@Override
public void run() {

}
});
}

@Override
public void onFail(int errorCode) {
Log.e(TAG, "网络请求返回的errorCode = " + errorCode);
}

});

mDefaultThreadPool.execute(asyncRequest);
mAsyncRequests.add(asyncRequest);

2、解析网络返回的JSON字符串：

服务器端返回的JSON字符串：

{
"renren_token":
{
"session_secret":"52e95c7b02abb0a80a4a80116438063a",
"expires_in":2595334,
"session_key":"6.8fed55fdfd5c027c2ecb0ac50859f97c.2592000.1367121600-461345584"
},
"oauth_token":"195789|6.8fed55fdfd5c027c2ecb0ac50859f97c.2592000.1367121600-461345584",
"user":
{
"id":461345584
}
}

对JSON字符串进行解析：

JSONObject jsonObject = new JSONObject(json);

JSONObject jsonRenrenToken = jsonObject.getJSONObject("renren_token");
String session_key = jsonRenrenToken.getString("session_key");
String session_secret = jsonRenrenToken.getString("session_secret");
long expires_in = jsonRenrenToken.getLong("expires_in");

String oauth_token = jsonObject.getString("oauth_token");
long userId = jsonObject.getJSONObject("user").getLong("id");

// 对Session过期时间进行处理，  Session过期时间 = 系统当前的时间 + 服务器端返回的Session过期时间。
long create_session_time = System.currentTimeMillis();
expires_in = create_session_time + expires_in*1000; // 服务器端返回的Session过期时间单位为秒，因此需要乘以1000

StringBuilder authResult = new StringBuilder();
authResult.append(" oauth_token = ").append(oauth_token);
authResult.append("\n session_key = ").append(session_key);
authResult.append("\n session_secret = ").append(session_secret);
authResult.append("\n expires_in = ").append(expires_in);
authResult.append("\n userId = ").append(userId);

Log.i(TAG, "解析后的值：\n" + authResult.toString());

三、采用SharedPreferences在本地保存Auth授权的信息，以便以后使用。

// 本地存储Authorization授权认证数据
Editor editor = mContext.getSharedPreferences("auth_config", Context.MODE_PRIVATE).edit();
editor.putString("session_key", session_key);
editor.putString("session_secret", session_secret);
editor.putLong("expires_in", expires_in);
editor.putLong("create_session_time", create_session_time);
editor.putString("oauth_token", oauth_token);
editor.putLong("userId", userId);
editor.commit();

四、切换界面到应用主界面

new  ResultCallback(){

@Override
public void onSuccess(final Object result) {
mHandler.post(new Runnable() {

@Override
public void run() {
if((Boolean)result)
{
Intent intent = new Intent(AuthActivity.this, EveryoneActivity.class);
AuthActivity.this.startActivity(intent);
} else {
Log.e(TAG, "网络请求返回的JSON值为NULL");
}
}
});
}

@Override
public void onFail(int errorCode) {
Log.e(TAG, "网络请求返回的errorCode = " + errorCode);
}

}

使用accessToken交换session等完整的代码如下：

/**
* 通过accessToken换取session_key、session_secret和userId
* @param accessToken
*/
private void exchangeSessionKey(String accessToken) {
if (accessToken == null || accessToken.length() < 1) {
return;
}

Map<String, String> parameter = new HashMap<String, String>();
parameter.put("oauth_token", accessToken);
AsyncBaseRequest asyncRequest = new AsyncHttpPost(Constant.SESSION_KEY_URL, parameter,
new ParseCallback (){

@Override
public Boolean parse(String json) throws JSONException {
Log.e(TAG, "result = " + json);
if(!TextUtils.isEmpty(json)){

// 服务器端返回的JSON字符串：
/*{
"renren_token":
{
"session_secret":"52e95c7b02abb0a80a4a80116438063a",
"expires_in":2595334,
"session_key":"6.8fed55fdfd5c027c2ecb0ac50859f97c.2592000.1367121600-461345584"
},
"oauth_token":"195789|6.8fed55fdfd5c027c2ecb0ac50859f97c.2592000.1367121600-461345584",
"user":
{
"id":461345584
}
}*/

// 解析JSON
JSONObject jsonObject = new JSONObject(json);

JSONObject jsonRenrenToken = jsonObject.getJSONObject("renren_token");
String session_key = jsonRenrenToken.getString("session_key");
String session_secret = jsonRenrenToken.getString("session_secret");
long expires_in = jsonRenrenToken.getLong("expires_in");

String oauth_token = jsonObject.getString("oauth_token");
long userId = jsonObject.getJSONObject("user").getLong("id");

// 对Session过期时间进行处理，  Session过期时间 = 系统当前的时间 + 服务器端返回的Session过期时间。
long create_session_time = System.currentTimeMillis();
expires_in = create_session_time + expires_in*1000; // 服务器端返回的Session过期时间单位为秒，因此需要乘以1000

StringBuilder authResult = new StringBuilder();
authResult.append(" oauth_token = ").append(oauth_token);
authResult.append("\n session_key = ").append(session_key);
authResult.append("\n session_secret = ").append(session_secret);
authResult.append("\n expires_in = ").append(expires_in);
authResult.append("\n userId = ").append(userId);

Log.i(TAG, "解析后的值：\n" + authResult.toString());

// 本地存储Authorization授权认证数据
Editor editor = mContext.getSharedPreferences("auth_config", Context.MODE_PRIVATE).edit();
editor.putString("session_key", session_key);
editor.putString("session_secret", session_secret);
editor.putLong("expires_in", expires_in);
editor.putLong("create_session_time", create_session_time);
editor.putString("oauth_token", oauth_token);
editor.putLong("userId", userId);
editor.commit();

return true;

}
return false;
}

},
new  ResultCallback(){

@Override
public void onSuccess(final Object result) {
mHandler.post(new Runnable() {

@Override
public void run() {
if((Boolean)result)
{
Intent intent = new Intent(AuthActivity.this, EveryoneActivity.class);
AuthActivity.this.startActivity(intent);
} else {
Log.e(TAG, "网络请求返回的JSON值为NULL");
}
}
});
}

@Override
public void onFail(int errorCode) {
Log.e(TAG, "网络请求返回的errorCode = " + errorCode);
}

});

mDefaultThreadPool.execute(asyncRequest);
mAsyncRequests.add(asyncRequest);
}

好了就先到这里吧，不早了，晚安！
