使用Google应用程序脚本OAuthConfig类进行Shopify身份验证

我正在尝试通过google javascrip与我的shopify商店建立联系.身份验证的架构应类似于您可以在twitter的google文档中找到的架构.我正在尝试以下代码，但始终会收到错误:{"errors":"[API]无效的API密钥或访问令牌(无法识别的登录名或错误的密码)"}

I am trying to connect with my shopify shop through the google javascrip. The schema for authentication should be something similar to the one you can find on google documentation for twitter. I'am trying the following code, but I always get the error:{"errors":"[API] Invalid API key or access token (unrecognized login or wrong password)"}

function getInfofromshopify() {
var handle = "01-02-0316_cmt_utensili"
var urljson ="https://mysitename.myshopify.com/admin/products.json?handle="+handle;
var oAuthConfig = UrlFetchApp.addOAuthService("shopify");
oAuthConfig.setAccessTokenUrl("https://mysitename.myshopify.com/admin/oauth/access_token");
oAuthConfig.setRequestTokenUrl("https://mysitename.myshopify.com/admin/oauth/access_token");
oAuthConfig.setAuthorizationUrl("https://mysitename.myshopify.com/admin/oauth/authorize");
oAuthConfig.setConsumerKey(API_KEY);
oAuthConfig.setConsumerSecret(Shared_secret);
var options =
{
"oAuthServiceName" : "shopify",
"oAuthUseToken" : "always"
};
var response = UrlFetchApp.fetch(urljson,options);
var responsestr = response.getContentText();
var result = Utilities.jsonParse(responsestr)
}
