如何在ShopifySharp .Net库中正确获取访问令牌？

Question

我使用https://github.com/nozzlegear/ShopifySharp .Net库来使用Shopify Api。我刚刚创建了dev webshop，我想测试一些GET方法。在文档中我看到了下面的代码：

string code = Request.QueryString["code"];
string myShopifyUrl = Request.QueryString["shop"];

string accessToken = await AuthorizationService.Authorize(code, myShopifyUrl, shopifyApiKey, shopifySecretKey); 

我理解的所有参数，除了第一，这是什么代码，我应该从哪里获得它？？谢谢

Answer 1

这基本上是授权代码

它是关于"OAuth"的概念的

参考：https://help.shopify.com/api/getting-started/authentication/oauth

Answer 2

您应该在您的控制器中创建一个方法，它将接收来自Shopify的回调：

public ActionResult Callback(string code, string shop) {
    string accessToken = await AuthorizationService.Authorize(code, myShopifyUrl, shopifyApiKey, shopifySecretKey); 
}

然后在构建授权URL时，您应该将变量redirectUrl设置为上面的方法：

//This is the user's store URL.
string usersMyShopifyUrl = "https://example.myshopify.com";

// A URL to redirect the user to after they've confirmed app installation.
// This URL is required, and must be listed in your app's settings in your Shopify app dashboard.
// It's case-sensitive too!
string redirectUrl = "https://example.com/my/redirect/url";

//An array of the Shopify access scopes your application needs to run.
var scopes = new List<AuthorizationScope>()
{
    AuthorizationScope.ReadCustomers,
    AuthorizationScope.WriteCustomers
};

//Or, use an array of string permissions
var scopes = new List<string>()
{
    "read_customers",
    "write_customers"
}

//All AuthorizationService methods are static.
string authUrl = AuthorizationService.BuildAuthorizationUrl(scopes, usersMyShopifyUrl, shopifyApiKey, redirectUrl);

一旦用户将被重定向到授权URL，它将打开购物页面，用户将能够安装应用程序。然后，Shopify会使用code和shop参数将他重定向到您的回调方法
