Question

我正在尝试使用以下json和c＃代码更新shopify中现有变体的库存：

    var p = new
    {
            id = "220994352",
            inventory_quantity = "0"
    };

    string url = "https://somestore.myshopify.com/admin/variants/220994352.json";

    ShopifyAuthorizationState authState = (ShopifyAuthorizationState)HttpContext.Current.Session["shopify_auth_state"];
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    request.Method = "PUT";
    request.ContentType = "application/json";
    request.Headers.Add("X-Shopify-Access-Token", authState.AccessToken);

    var serializer = new JavaScriptSerializer();
    var json = serializer.Serialize(p);
    json = "{ variant: " + json + "}";

    if (!String.IsNullOrEmpty(json))
    {
        using (var ms = new MemoryStream())
        {
            using (var writer = new StreamWriter(request.GetRequestStream()))
            {
                writer.Write(json);
                writer.Close();
            }
        }
    }


    string result = "";
    try
    {
        var response = (HttpWebResponse)request.GetResponse();
        using (Stream stream = response.GetResponseStream())
        {
            StreamReader sr = new StreamReader(stream);
            result = sr.ReadToEnd();
            sr.Close();
        }
    }
    catch (WebException ex)
    {
        WebHeaderCollection webHeaderCollection = ex.Response.Headers;
        foreach (var header in ex.Response.Headers.AllKeys)
        {
            Console.WriteLine(webHeaderCollection[header]);
        }
    }

然而，每次我运行这个时，我都会收到400 Bad请求，但没有关于错误的详细信息。我没有任何问题就阅读了库存。

Answer 1

您是否确定在授权应用程序时设置了作用域权限，以便对产品具有写入权限？

您是否可以发布原始http响应的链接，以显示确切返回的内容，包括标题以查看是否还有其他详细信息？

Answer 2

400错误请求通常意味着发送的数据无效。看着你的json可能对你有所帮助。尝试在json字符串中将变量放在变量周围。

更新Shopify Variant将返回400 Bad Request
