如何使用google-api-javascript-client和Javascript访问Google Photos API并读取JSON数据?

问题描述

我对使用API​​和使用OAuth获取JSON数据非常陌生.有人可以帮我吗?我正在尝试访问客户端google照片并阅读它们.这些代码段来自google photos文档.我对其进行了修改，但仍然出现错误:无法加载资源:服务器响应状态为401()"和未捕获{错误:"idpiframe_initialization_failed"，详细信息:客户端的无效来源: http://127.0.0 .…将此来源列出为项目的客户ID.}"谢谢！！！

I am very new to using API and getting JSON data using OAuth. Could anybody help me? I am trying to access clients google photos and read them. These code snippets are from google photos documentation. I modified it but still having error: "Failed to load resource: the server responded with a status of 401 ()" and "Uncaught {error: "idpiframe_initialization_failed", details: "Not a valid origin for the client: http://127.0.0.…itelist this origin for your project's client ID."}"Thank you!!!
