这一部分挺简单的，其实就是在页面上放一个链接，引导用户跳转即可
链接的格式如下：
这里对参数做一下说明
component_appid即第三方平台的APPID（如下图）
pre_auth_code为预授权码，用获得的第三方平台AccessToken作为参数进行获取，具体看下面的代码
redirect_uri为用户同意授权之后跳转的链接，同时会向该页面发送用户的授权码auth_code，通过这个授权码即可请求到公众号的授权信息
获取预授权码的函数
/// <summary> /// 用于获取预授权码。预授权码用于公众号授权时的第三方平台方安全验证 /// </summary> /// <param name="component_verify_ticket"></param> /// <returns></returns> public static ResponseCreatePreauthCode Create_preauthcode(string component_access_token) { var urlFormat = "https://api.weixin.qq.com/cgi-bin/component/api_create_preauthcode?component_access_token={0}"; object data = null; data = new { component_appid = Config.ServerAppID, }; return CommonJsonSend.Send<ResponseCreatePreauthCode>(component_access_token, urlFormat, data, timeOut: Config.TIME_OUT); }
返回结果示例
{
"pre_auth_code":"Cx_Dk6qiBE0Dmx4EmlT3oRfArPvwSQ-oa3NL_fwHM7VI08r52wazoZX2Rhpz1dEw",
"expires_in":600
}
获得用户授权码之后，用auth_Code作为参数请求公众号信息。
component_access_token为第三方平台accessToken
/// <summary> /// 使用授权码换取公众号的授权信息 /// </summary> /// <param name="component_access_token"></param> /// <returns></returns> public static PublicWechatAuthorizerInfo Query_auth(string component_access_token, string auth_code_value) { var urlFormat = "https://api.weixin.qq.com/cgi-bin/component/api_query_auth?component_access_token={0}"; object data = null; data = new { component_appid = Config.ServerAppID, authorization_code = auth_code_value }; return CommonJsonSend.Send<PublicWechatAuthorizerInfo>(component_access_token, urlFormat, data, timeOut: Config.TIME_OUT); }
返回结果示例
