访问Google API for Shopping时凭据无效

Question

我正在尝试使用google-api-client gem来访问Google Search API for Shopping。不幸的是，尽管我通过Google APIs Console创建了一个access_token，但我似乎无法进行身份验证。

下面是我的代码：

client = Google::APIClient.new
client.authorization.access_token = "<MY_CONSOLE_ACCESS_TOKEN>"
client.authorization.scope = "https://www.googleapis.com/auth/shoppingapi"

shopping = client.discovered_api("shopping", "v1")
response = client.execute(api_method: shopping.products.list,
                          parameters: { source: "public" })

当我查看response.data时，我看到一条错误消息：

#<Google::APIClient::Schema::Shopping::V1::Products:0x809d6e14 DATA:{"error"=>{"errors"=>[{"domain"=>"global", "reason"=>"authError", "message"=>"Invalid Credentials", "locationType"=>"header", "location"=>"Authorization"}], "code"=>401, "message"=>"Invalid Credentials"}}>

我做错了什么？

当然，我在发帖几分钟后就明白了。我将分享对任何其他有同样问题的人有效的方法。

client = Google::APIClient.new(authorization: nil)
shopping = client.discovered_api("shopping", "v1")
response = client.execute(key: "<MY_ACCESS_TOKEN>",
                          api_method: shopping.products.list,
                          parameters: { source: "public", country: "US" })
