Shopify访问令牌返回null

Question

在旅程即将结束时，我意识到我的访问令牌将为空。我在带有C#的visual studio中使用RectSharp来启动并运行shopify应用程序，一切都正常，直到按下安装键，然后我被带回visual studio，并被告知accessToken为空D:

这是一些错误和我调试的图片点击此处查看图像

这是我注意到的r附近弹出的错误，它是用rectSharp写的，在我看来是正确的。

{{
"error": "822: unexpected token at 'client_id=6e83a9e8b79dccbad77530c7273e3e00&client_secret=03cfa0ef9b451868bb0160e4ad75e0ec&code=3a941fe03d9fc0ea0d4226f9f4af316f'"
}}

这是我的身份验证码：

public ActionResult install(string shop, string signature, string timestamp)
{
string r = string.Format("https://{0}/admin/oauth/authorize?client_id={1}&scope=read_fulfillments,write_fulfillments,read_orders,write_products&redirect_uri=https://{2}/fulfillment/auth", shop, apiKey, appUrl);
return Redirect(r);
}
public ActionResult auth(string shop, string code)
{
string u = string.Format("https://{0}/admin/oauth/access_token", shop);
var client = new RestClient(u);
var request = new RestRequest(Method.POST);
request.RequestFormat = DataFormat.Json;
request.AddHeader("Content-Type", "application/json");
request.AddParameter("application/x-www-form-urlencoded", "client_id=" + apiKey + "&client_secret=" + secretKey + "&code=" + code, ParameterType.RequestBody);
var response = client.Execute(request);
var r = JsonConvert.DeserializeObject<dynamic>(response.Content);
var accessToken = r.access_token;
accesstokenmain = r.access_token;
//save shop token and information to database
SaveShopToken(shop, (string)accessToken);
//Part 5
//create a un-install web hook
//you want to know when customers delete your app from their shop
string unInstallUrlCallback = "https://8a047f39.ngrok.io/fulfillment/uninstall";
string shopAdmin = string.Format("https://{0}/admin/", shop);
var webHook = new WebHookBucket();
webHook.Whook = new WebHook { Format = "json", Topic = "app/uninstalled", Address = unInstallUrlCallback };
CreateUninstallHook(shopAdmin, "webhooks.json", Method.POST, (string)accessToken, webHook);
return Redirect(AskCustomerCharge(shop, (string)accessToken));

// return View();
}
public void SaveShopToken(string shop, string token)
{
using (var con = new fulfillmentdbEntities())
{
if (con.ShopTokens.Any(c=>c.Shop == shop))
{
} else
{
con.ShopTokens.Add(new ShopToken { Shop = shop, Token = token, InstallDate = DateTime.Now });
}
con.SaveChanges();
}
}

请按以下更改request.AddHeader和request.AddParameter

request.AddHeader("content-type", "application/x-www-form-urlencoded");
request.AddParameter("application/x-www-form-urlencoded", $"client_id={apiKey}&client_secret={secretKey}&code={code}, ParameterType.RequestBody);
