微信的jssdk授权，php版本，和一些坑

首先我下面的代码即将过期，授权方法不知道怎样会不会改，我不知道你是什么时候看到我这篇文章，所以要注意

他把微信qq的朋友圈和空间接口放到一起了，所以注意，而且这个接口需要导入的js起码要1.4版本这个是坑

 

首先公众号检查，给服务器ip地址白名单，（内网和外网都要），然后添加域名回调名单。有三个名额。这个都有了后，然后去复制openid和密匙，到下面的授权代码

getSignPackage();
echo json_encode($signPackage);
}

jssdk_wx.php

appId = func_get_arg(0);
		$this->appSecret = func_get_arg(1);
		$this->posturl = func_get_arg(2);
	}else if($postnums==2){

		$this->appSecret = func_get_arg(1);
		$this->posturl = '';
