问题描述
- 列表项
我创建了一个适用于HTTP请求的Google App脚本REST-应用程序(以"script.google.com/"开头).
I have created a Google App Script REST - Application (starting with "script.google.com/"), that works with HTTP-requests.
该应用程序对所有人(甚至匿名)都可用"时工作正常，但是当我将其设置为仅对我的域可用时或从发布/部署"为WebApp [/EDIT]的仅我自己"，我只能使用浏览器和登录访问Web应用，而不能使用http请求访问.
The application works fine when it is available to 'everyone, even anonymous' but when I set it available to my domain only OR "only myself" from the publish/deploy as WebApp[/EDIT], I can only access the web app with browser and signing in but not with http request.
我尝试通过Google OAuth Playground 和基于 Xamarin认证教程.
I have tried requesting an authorization token with both Google OAuth Playground and an android application based on a Xamarin Auth Tutorial.
这两种方法都使我获得了有效的授权令牌，可以将其复制+粘贴到另一个平台，并确认它是否正在处理对 https://wwww.googlapis.com/plus/v1/people/me .
Both methods have resulted me a working authorization token that I can copy+paste to an other platform an confirm it is working with a request to https://wwww.googlapis.com/plus/v1/people/me.
我可以使用浏览器访问Web应用程序并登录.现在，当我使用http请求调用脚本时，将得到以下结果:
I can access the Web app with browser and signing in. Now when I call my script with http request I get the following result:
"<HTML> <HEAD> <TITLE>Unauthorized</TITLE> </HEAD> <BODY BGCOLOR="#FFFFFF" TEXT="#000000"> <H1>Unauthorized</H1> <H2>Error 401</H2> </BODY> </HTML>"
我尝试使用另一个应用程序脚本来调用Web应用程序:
I have tried to call the Web App with another App Script:
var headers = {
"authorization": "Bearer [access_token]",
};
var params = {
method:"GET",
contentType:"application/json",
muteHttpExceptions:true,
headers:headers,
};
var url = "https://script.google.com/[rest_of_the_script_url]";
var response = UrlFetchApp.fetch(url, params);
我还尝试使用C#OAuth2Request调用Web应用程序(来自Xamarin教程):
Also I have tried calling the Web App with C# OAuth2Request (Taken from the Xamarin tutorial):
var url = "https://script.google.com/[rest_of_the_script_url]";
var request = new OAuth2Request("GET", new Uri(url), null, account );
我也尝试过C#HttpWebRequest:
Also I have tried C# HttpWebRequest:
string accessToken = "Bearer [access_token]";
string url = "[https://script.google.com/[rest_of_the_script_url]";
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.create(url);
request.Method = "GET";
request.ContentType = "application/json";
request.Headers.Add("Authorization", accessToken);
var response = request.getResponse();
所有以前的方法都具有相同的结果:(401)未经授权".
All previous methods have the same result: "(401) Unauthorized".
对于我设置的范围:
https://www.googleapis.com/auth/plus.me
https://www.googleapis.com/auth/userinfo.email
我的WebApp根据其属性不需要任何范围.还要确保没有，我没有设置一个尽可能简单的doGet()方法:
My WebApp does not require any scopes according to it's properties. Also to make sure it does not I did set a doGet() method as simple as possible:
function doGet(e)
{
return ContentService.CreateTextOutput("success");
}
此问题曾被问过，但有些人找到了解决方法，而有些则没有.同样，我也没有成功的答案.
This question has been asked before, but some have found the solution and some have not. Also I did not success with the answers either.
- I think my first attempt covers this one.
- I tried to translate the Java answer to C#
好的，感谢您在这里阅读，希望当我用尽所有想法(最终是时间)时，有人可以帮助我解决这个问题.
Ok, thanks for reading down here, wish some one can help me out with this as I'm running out of ideas (and time, eventually).
尽管该问题已解决并证明是范围问题，但我还是在下面的评论中回答这些问题，以防万一该问题将来对任何人都有帮助.
Though the issue has resolved and turned out to be a scope-issue I am answering the questions in the comments below, in case this question might be of any help to anyone in the future.
推荐答案
我能够将其与Google OAuth Playground中https://www.googleapis.com/auth/drive.file范围授权的访问令牌一起使用.
I was able to get this to work with an access token authorized with the https://www.googleapis.com/auth/drive.file scope in the Google OAuth Playground.
在我看来，这似乎不太对劲，但这是我必须从事的最宽松的范围.
That doesn't seem quite right in my opinion, but it's the least permissive scope I got to work.
