测试回调模式地址https://open.work.weixin.qq.com/wwopen/devtool/interface/combine，建立连接 => 测试回调模式
测试回调成功，但是发现返回结果带了引号，可能是导致回调不成功原因。下面代码为错误示范。
[HttpGet, Route("callback/interAspect")]
public IActionResult ReveiceMsg(string msg_signature,string timestamp,string nonce,string echostr)
{
//验证
WXBizMsgCrypt wxcpt = new WXBizMsgCrypt(AppSetting.Configuration["Wx:CallBackToken"]
, AppSetting.Configuration["Wx:EncodingAESKey"]
, AppSetting.Configuration["Wx:corpid"]);
int ret = 0;
string sEchoStr = "";
ret = wxcpt.VerifyURL(msg_signature, timestamp, nonce, echostr, ref sEchoStr);
if (ret != 0)
{
return Json(null);
}
return Json(sEchoStr);
}返回值调整为ContentResult 或者string 后测试成功。
[HttpGet, Route("callback/interAspect")]
public ContentResult ReveiceMsg(string msg_signature,string timestamp,string nonce,string echostr)
{
//验证
WXBizMsgCrypt wxcpt = new WXBizMsgCrypt(AppSetting.Configuration["Wx:CallBackToken"]
, AppSetting.Configuration["Wx:EncodingAESKey"]
, AppSetting.Configuration["Wx:corpid"]);
int ret = 0;
string sEchoStr = "";
ret = wxcpt.VerifyURL(msg_signature, timestamp, nonce, echostr, ref sEchoStr);
if (ret != 0)
{
return Content(null);
}
return Content(sEchoStr);
}最后成功保存
