标题：如何使用ShareSDK实现Cocos2d-x的Android/iOS分享与授权

Posted 2021-12-02 mobjun

Cocos2DX 简介

Cocos2d-x是一套成熟的开源跨平台游戏开发框架。其引擎提供了图形渲染、GUI、音频、网络、物理、用户输入等丰富的功能，被广泛应用于游戏开发及交互式应用的构建。引擎的核心采用C++ 编写，支持使用C++、Lua或者javascript进行开发。同时Cocos2d-x可以适配ios、android、html5、Windows和Mac系统。

Cocos2d-x在中国及全球都有一定的市场份额，为了给开发出来的游戏增加知名度，更好的进行营销，社交分享功能是必不可少的。但是所要分享的平台针对全球不同的区域有不同的侧重点，这就需要短时间内接入多个社交平台，但是每个平台的接入时间成本按天计算，多个平台叠加在一起的时间就很不乐观。所以使用Cocos2d-x引擎的开发人员急需一种能够让开发者快速接入授权、分享功能的SDK。

Cocos2d-x集成ShareSDK过程如下：

• 产品主页网址：http://www.mob.com/product/sharesdk
• 官方插件地址：https://github.com/MobClub/New-C2DX-For-ShareSDK

Android 集成

首先下载官方插件，下载完毕之后需要做如下几步工作

1. 把ShareSDK的cocos2dx的proj.android-studio项目里的libs包复制到你的项目里，除了armeabi目录不用复制其他都要。

2. 把ShareSDK的cocos2dx的New-C2DX-For-ShareSDK项目里的Classes目录下的文件都复制到你的项目里的Classes目录下。

3. 在jni/Android.mk添加下面代码来引入相关文件，如：

   ../../Classes/AppDelegate.cpp    ../../Classes/HelloWorldScene.cpp    ../../Classes/C2DXShareSDK/Android/ShareSDKUtils.cpp    ../../Classes/C2DXShareSDK/C2DXShareSDK.cpp    ../../Classes/C2DXShareSDK/Android/JSON/CCJSONConverter.cpp    ../../Classes/C2DXShareSDK/Android/JSON/cJSON/cJSON.c
   
   
   LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes 
      $(LOCAL_PATH)/../../Classes/C2DXShareSDK    $(LOCAL_PATH)/../../Classes/C2DXShareSDK/Android    $(LOCAL_PATH)/../../Classes/C2DXShareSDK/Android/JSON    $(LOCAL_PATH)/../../Classes/C2DXShareSDK/Android/JSON/cJSON
   

4. 在proj.android-studio工程下，app目录下，build.gradle文件内，寻找到dependencies标签，配置如下的代码

   compile project(‘:libcocos2dx‘)
   

5. 在主activity里(一般在cocos项目的此目录下面：\proj.android-studio\src\org\cocos2dx\cpp\AppActivity.java)的onCreate方法里添加ShareSDKUtils.prepare()方法。

   protected void onCreate(Bundle savedInstanceState){
           super.onCreate(savedInstanceState);
           ShareSDKUtils.prepare();
   }
   

6. 各个平台的配置方式：平台的配置在libcocos2dx这个依赖工程内，工程根目录下边有一个MobSDK.gradle文件，写法示例如下边的代码所示，用户需要用自己申请到的Key来替换下文中的key。平台的选择也根据自己的需要来进行增加删除。

   apply plugin: ‘com.mob.sdk‘
   MobSDK {
       appKey "moba6b6c6d6"
       appSecret "b89d2427a3bc7ad1aea1e1e8c1d36bf3"
   
       ShareSDK {
           //平台配置信息
           devInfo {
               SinaWeibo {
                   id 1
                   sortId 1
                   appKey "568898243"
                   appSecret "38a4f8204cc784f81f9f0daaf31e02e3"
                   callbackUri "http://www.sharesdk.cn"
                   shareByAppClient true
                   enable true
               }
   
               QZone {
                   id 3
                   sortId 3
                   appId "100371282"
                   appKey "aed9b0303e3ed1e27bae87c33761161d"
                   shareByAppClient true
                   bypassApproval false
                   enable true
               }
   
               QQ {
                   id 7
                   sortId 7
                   appId "100371282"
                   appKey "aed9b0303e3ed1e27bae87c33761161d"
                   shareByAppClient true
                   bypassApproval false
                   enable true
               }
   
    			Wechat {
                   id 4
                   sortId 4
                   appId "wx4868b35061f87885"
                   appSecret "64020361b8ec4c99936c0e3999a9f249"
                   userName "gh_b0c6a9ca668a"
                   path "pages/index/index?id=mob"
                   withShareTicket true
                   miniprogramType 2
                   bypassApproval false
                   enable true
               }
   
               WechatMoments {
                   id 5

                   bypassApproval false
                   enable true
               }
   
               WechatFavorite {
                   id 6
                   sortId 6
                   appId "wx4868b35061f87885"
                   appSecret "64020361b8ec4c99936c0e3999a9f249"
                   bypassApproval false
                   enable true
               }
               
               Facebook {
                   id 8
                   sortId 8
                   appKey "1412473428822331"
                   appSecret "a42f4f3f867dc947b9ed6020c2e93558"
                   callbackUri "https://mob.com"
                   shareByAppClient true
                   enable true
               }
   
               Twitter {
                   id 9
                   sortId 9
                   appKey "viOnkeLpHBKs6KXV7MPpeGyzE"
                   appSecret "NJEglQUy2rqZ9Io9FcAU9p17omFqbORknUpRrCDOK46aAbIiey"
                   callbackUri "http://mob.com"
                   shareByAppClient true
                   enable true
               }
               
           }
       }
   }
   
   

iOS 集成

1. 将下面红色方框的资源文件拖到Cocos2d-x项目中

   

2. 将SDK文件夹拖进项目（下载地址） 注意：请务必在上述步骤中选择“Create groups for any added folders”单选按钮组。如果你选择“Create folder references for any added folders”，一个蓝色的文件夹引用将被添加到项目并且将无法找到它的资源。

3. 添加必须的依赖库

   • libc++.tbd
   • libz.tbd
   • libsqlite3.tbd

各社交平台所需依赖库：

新浪微博：

• ImageIO.framework
• Photos.framework

Instagram：

• AssetsLibrary.framework
• Photos.framework

美拍：

• AssetsLibrary.framework

添加依赖库的方法如下

3. 配置UrlScheme和白名单等，各个社交平台需要的配置可以参考快速集成文档中的URL Scheme和白名单配置项。

4. 在项目工程的Info.plist 中如图增加 MOBAppKey 和 MOBAppSecret 两个字段

   在 MOBAppKey中 设置ShareSDK的appKey，如果尚未在ShareSDK官网注册过App，请移步到 登录后台 进行应用注册也可以点击 链接 看里面的操作步骤。

   

代码实现

• 初始化： 打开Classes目录下边的AppDelegate.cpp文件，直接拷贝粘贴代码进行初始化工作。

  导入头文件

  # include "C2DXShareSDK.h"
  

  初始化

  
      bool AppDelegate::applicationDidFinishLaunching()
      {
          //初始化ShareSDK
          this->initShareSDKConfig();
      }
      
      void AppDelegate::initShareSDKConfig()
      {
          //设置平台配置
           //Platforms
           __Dictionary *totalDict = __Dictionary::create();
           
           //新浪微博
           __Dictionary *sinaWeiboConf= __Dictionary::create();
           sinaWeiboConf->setObject(__String::create("568898243"), "app_key");
           sinaWeiboConf->setObject(__String::create("38a4f8204cc784f81f9f0daaf31e0 2e3"), "app_secret");
           sinaWeiboConf->setObject(__String::create("http://www.sharesdk.cn"), "re direct_uri");
           stringstream sina;
           sina << cn::sharesdk::C2DXPlatTypeSinaWeibo;
           totalDict->setObject(sinaWeiboConf, sina.str());
           
           //微信
           __Dictionary *wechatConf = __Dictionary::create();
           wechatConf->setObject(__String::create("wx4868b35061f87885"), "app_id");
           wechatConf->setObject(__String::create("64020361b8ec4c99936c0e3999a9f249 "), "app_secret");
           stringstream wechat;
           wechat << cn::sharesdk::C2DXPlatTypeWechatPlatform;
           totalDict->setObject(wechatConf, wechat.str());
           
           //QQ
           __Dictionary *qqConf = __Dictionary::create();
           qqConf->setObject(__String::create("100371282"), "app_id");
           qqConf->setObject(__String::create("aed9b0303e3ed1e27bae87c33761161d"),  "app_key");
           stringstream qq;
           qq << cn::sharesdk::C2DXPlatTypeQQPlatform;
           totalDict->setObject(qqConf, qq.str());
           
           //Facebook
           __Dictionary *fbConf = __Dictionary::create();
           fbConf->setObject(__String::create("107704292745179"), "api_key");
           fbConf->setObject(__String::create("38053202e1a5fe26c80c753071f0b573"),  "app_secret");
           stringstream facebook;
           facebook << cn::sharesdk::C2DXPlatTypeFacebook;
           totalDict->setObject(fbConf, facebook.str());
           
           //Twitter 
           __Dictionary *twConf = __Dictionary::create();
           twConf->setObject(__String::create("LRBM0H75rWrU9gNHvlEAA2aOy"), "consumer_key");
           twConf->setObject(__String::create("gbeWsZvA9ELJSdoBzJ5oLKX0TU09UOwrzdGfo9Tg7DjyGuMe8G"), "consumer_secret");
           twConf->setObject(__String::create("http://www.mob.com"), "redirect_uri" ) ;
           stringstream twitter;
           twitter << cn::sharesdk::C2DXPlatTypeTwitter;
           totalDict->setObject(twConf, twitter.str());
           
           cn::sharesdk::C2DXShareSDK::registerAppAndSetPlatformConfig("moba6b6c6d6","b89d2427a3bc7ad1aea1e1e8c1d36bf3",totalDict);
      }
  

  以上平台的app_key、app_secret等字段不同分享平台可能不同，详情可参考：《统一表》。

• 授权功能：

  C2DXShareSDK::authorize(C2DXPlatTypeSinaWeibo, authResultHandler);
  

  authResultHandler是默认定制的一个回调类，也可以自己写一个新的回调类来替代此类

  //授权回调
  void authResultHandler(int seqId, cn::sharesdk::C2DXResponseState state, cn::sharesdk::C2DXPlatType platType, __Dictionary *result)
  {
      switch (state)
      {
          case cn::sharesdk::C2DXResponseStateSuccess:
          {
              log("Success");
              
              //输出信息
              try
              {
                  __Array *allKeys = result -> allKeys();
                  allKeys->retain();
                  for (int i = 0; i < allKeys -> count(); i++)
                  {
                      __String *key = (__String *)allKeys -> getObjectAtIndex(i);
                      Ref *obj = result -> objectForKey(key -> getCString());
                      
                      log("key = %s", key -> getCString());
                      if (dynamic_cast<__String *>(obj))
                      {
                          log("value = %s", dynamic_cast<__String *>(obj) -> getCString());
                      }
                      else if (dynamic_cast<__Integer *>(obj))
                      {
                          log("value = %d", dynamic_cast<__Integer *>(obj) -> getValue());
                      }
                      else if (dynamic_cast<__Double *>(obj))
                      {
                          log("value = %f", dynamic_cast<__Double *>(obj) -> getValue());
                      }
                  }
                  allKeys->release();
              }
              catch(...)
              {
                  log("==============error");
              }
          }
              break;
          case cn::sharesdk::C2DXResponseStateFail:
          {
              log("Fail");
              //回调错误信息
              __Array *allKeys = result->allKeys();
              allKeys->retain();
              for (int i = 0; i < allKeys-> count(); i++)
              {
                  __String *key = (__String*)allKeys->getObjectAtIndex(i);
                  Ref *obj = result->objectForKey(key->getCString());
                  
                  log("key = %s", key -> getCString());
                  if (dynamic_cast<__String *>(obj))
                  {
                      log("value = %s", dynamic_cast<__String *>(obj) -> getCString());
                  }
                  else if (dynamic_cast<__Integer *>(obj))
                  {
                      log("value = %d", dynamic_cast<__Integer *>(obj) -> getValue());
                  }
                  else if (dynamic_cast<__Double *>(obj))
                  {
                      log("value = %f", dynamic_cast<__Double *>(obj) -> getValue());
                  }
              }
          }
              break;
          case cn::sharesdk::C2DXResponseStateCancel:
          {
              log("Cancel");
          }
              break;
          default:
              break;
      }
  }
  

• 获取用户的信息

  授权之后，可以通过如下的方法来获取用户信息。

  C2DXShareSDKC ::getUserInfo(C2DXPlatTypeSinaWeibo, getUserResultHandler);
  

• 分享

1. 在需要分享操作的代码块中进行构造分享参数，示例如下：

   __Dictionary *content = __Dictionary::create();
    content -> setObject(__String::create("分享文本"), "text");  // 分享文本
    content -> setObject(__String::create("HelloWorld.png"), "image");// 分享图片
    content -> setObject(__String::create("测试标题"), "title"); // 分享标题
    content -> setObject(__String::create("http://www.mob.com"), "url"); // 分享url
    content -> setObject(__String::createWithFormat("%d", cn::sharesdk::C2DXContentTypeWebPage), "type"); /
    
   

   构造分享内容字段参数值请参考：《分享内容字段值表》

2. 调用分享方法：

   //弹出菜单
   C2DXShareSDK::showShareMenu(NULL,content,100,100, shareContentResultHandler);// 第3，4个参数传入 iPad 视图要显示的坐标点，详见API说明
   
   //无UI，直接分享
   C2DXShareSDK::shareContent(cn::sharesdk::C2DXPlatTypeSinaWeibo, content, shareContentResultHandler);
    
   //弹出编辑界面分享
   C2DXShareSDK::showShareView(cn::sharesdk::C2DXPlatTypeSinaWeibo, content, shareContentResultHandler);
   

3. 设置分享回调方法 shareContentResultHandler，示例如下：

   //分享回调
   void shareContentResultHandler(int seqId, cn::sharesdk::C2DXResponseState state, cn::sharesdk::C2DXPlatType platType, __Dictionary *result)
   {
       switch (state)
       {
           case cn::sharesdk::C2DXResponseStateSuccess:
           {
               log("Success");
           }
               break;
           case cn::sharesdk::C2DXResponseStateFail:
           {
               log("Fail");
               //回调错误信息
               __Array *allKeys = result->allKeys();
               allKeys->retain();
               for (int i = 0; i < allKeys-> count(); i++)
               {
                   __String *key = (__String*)allKeys->getObjectAtIndex(i);
                   Ref *obj = result->objectForKey(key->getCString());
    
                   log("key = %s", key -> getCString());
                   if (dynamic_cast<__String *>(obj))
                   {
                       log("value = %s", dynamic_cast<__String *>(obj) -> getCString());
                   }
                   else if (dynamic_cast<__Integer *>(obj))
                   {
                       log("value = %d", dynamic_cast<__Integer *>(obj) -> getValue());
                   }
                   else if (dynamic_cast<__Double *>(obj))
                   {
                       log("value = %f", dynamic_cast<__Double *>(obj) -> getValue());
                   }
               }
           }
               break;
           case cn::sharesdk::C2DXResponseStateCancel:
           {
               log("Cancel");
           }
               break;
           default:
               break;
       }
   }
