尽管已颁发有效令牌，但仍从 Dynamics 365 取回 401 [英] Getting back 401 from Dynamics 365 despite being issued valid token

问题描述

我正在尝试使用 JavaScript 重写当前连接到 Dynamics 365 的客户端应用

let URL = "https://.operations.dynamics.com/data/FinancialDimensionValues?cross-company=true";让身体 = '';var headers = {'Content-Type':'application/json'};让响应 = ai.https.authorizedRequest(URL, 'GET', body, headers);

目前这个 JavaScript 应用程序可以工作并取回 JSON 数据.我正在尝试使用 C# 重写此应用程序.我首先从 Postman 开始，以确保在继续编写 C# 代码之前我已完成所有身份验证步骤.

使用 Postman，我能够使用客户端凭据"流成功获取 JWT 令牌，在该流中我将客户端 ID 和客户端密钥传递到访问令牌请求 URL.但是，当尝试访问 Dynamics 365 中的 API 端点时，即使我正确传递了 JWT 访问令牌，我也会收到 HTTP 401.

这是访问令牌请求 URL:

https://login.microsoftonline.com/722b0db7-9629-4304-92a0-dfb4a1debe62/oauth2/token?resource=https://<company-domain-here>.dynamics.com

我想我必须正确进行身份验证，否则我将无法取回有效的访问令牌.此外，由于 JavaScript 应用程序已经就位，可以正常工作，我假设 Dynamics 365 已正确配置以允许 API 访问.

我想弄清楚的是我在 Postman 中可能做错了什么导致我收到 401?有效的 JavaScript 请求与我通过 Postman 发送的请求有何不同?

解决方案

问题终于解决了.如前所述，请遵循

I am attempting to rewrite a client app that currently connects to Dynamics 365 using JavaScript

let URL = "https://<company-name>.operations.dynamics.com/data/FinancialDimensionValues?cross-company=true";
let  body = '';
var headers = {'Content-Type':'application/json'};
let response = ai.https.authorizedRequest(URL, 'GET', body, headers);

Currently this JavaScript application works and gets back JSON data. I am attempting to rewrite this application using C#. I am first starting with Postman to make sure I have all the authentication steps in place before moving on the writing the C# code.

Using Postman I am able to successfully obtain a JWT token using the "Client Credentials" flow where I pass the Client ID and the Client Secret to the Access Token Request URL. However, when trying to access an API endpoint within Dynamics 365 I receive back an HTTP 401 even though I am passing the JWT access token properly.

Here is the Access Token Request URL:

https://login.microsoftonline.com/722b0db7-9629-4304-92a0-dfb4a1debe62/oauth2/token?resource=https://<company-domain-here>.dynamics.com

I am thinking that I must be authenticating properly or I would not get back a valid access token. Also since the JavaScript application already in place works without issue I am assuming that Dynamics 365 is provisioned properly to allow API access.

What I am trying to figure out is what I might be doing wrong within Postman that results in my receiving a 401? What could be different between the working JavaScript request and what I am sending via Postman?

解决方案

Issue is finally solved. As mentioned follow the documentation mentioned.

If you face 401 Error, here is the last trick.

In postman Under Authorization--> Add authorization data to--> select Request Headers.

Now fire the query you shall have the 200 ok.
