C#：如何在 header 中使用不记名令牌获取请求

Question

Hello everyone my name is Taniguchi.

I've tried retrieving an entity from Dynamics 365 Finance and Operations and i did it on postman but now i having difficulties in asp.net core I was able to get the token but when i try to retrieve the entity the response gives me a html and this html leads me to the Dynamics 365 Finance and Operations Page. My code: `

        var httpClient = new HttpClient();

        httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);

        const string environmentsUri = "https://trial-0z4qfj.sandbox.operations.dynamics.com/data/PartyContacts";

        var response = httpClient.GetAsync(environmentsUri).Result;

        var content = response.Content.ReadAsStringAsync().Result;

what am i doing wrong? do i need to authenticate again?

Answer 1

I suspect the Token you receive is not correct/complete. I remember I faced the similar issue, I would request you to follow this blog post and try to receive Token as shown This shall help you solve your issue.

In addition I would recommend you use Organizaiton service with Webapi/Access Token. It will give you native library usage and you could query crm easily.

Try this blog for Orgservice

Seems like you are only using the parameter accessToken instead of the variable value. Depends on how you declared accessToken ofc. The rest seems fine.

Try:

httpClient.DefaultRequestHeaders.Authorization =
    new AuthenticationHeaderValue("Bearer", token.accessToken);
