[BUG] 获取微信OpenId异常

[ljc1160]

近期调用微信登录异常如下： Call failed. Resource temporarily unavailable (api.weixin.qq.com:443): GET https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=aaa&secret=bbb

百度后说微信 http keep-alive 时长为 20s，若20s后使用原始连接会报以上错误，对应帖子连接：https://juejin.cn/post/6865277186438496269

但实际代码中不存在超过20s的连接，且之前请求一直正常，对应代码如下，请协助解决，谢谢

// 获取连接 var client = CreateWeChatOpenClient();

var request = new CgibinTokenRequest(); var response = await client.ExecuteCgibinTokenAsync(request);

if (!response.IsSuccessful()) { throw new ApiResultException(ApiResultCodes.ServerInnerException, $"获取微信Token失败"); }

var openRequest = new SnsJsCode2SessionRequest { JsCode = code, AccessToken = response.AccessToken };

await client.ExecuteSnsJsCode2SessionAsync(openRequest, contextAccessor.HttpContext.RequestAborted);

偶发性的还是稳定复现？
