在 Postman 中運行對 Design Automation API 的調用工作得很好，但是當我嘗試使用 HttpClient 在 C# 中進行相同的調用時，它們失敗并顯示 404，這似乎實際上隱藏了身份驗證錯誤：{ "developerMessage":"The requested resource does not exist.", "userMessage":"", "errorCode":"ERR-002", "more info":"http://developer.api.autodesk.com/documentation/v1/errors/err-002"}該鏈接導致身份驗證錯誤：<Error> <Code>AccessDenied</Code> <Message>Access Denied</Message> <RequestId>1F52E60A45AEF429</RequestId> <HostId> [ Some base64 ] </HostId></Error>我正在關注如何使用 HttpClient 的示例，但我可能遺漏了一些東西。我成功獲取了訪問令牌，運行var client = new HttpClient{ BaseAddress = new Uri("https://developer.api.autodesk.com/da/us-east")};client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue(TokenType, AccessToken);然后var result = await client.GetAsync("/v3/forgeapps/me");而上面的json就是結果的內容。我在 Postman 中使用相同的訪問令牌并且它有效。

我會在 HttpRequestMessage 中包含端點、標頭和 httpmethod。然后發送并賦值給HttpResponseMessage。
var client = new HttpClient
{
BaseAddress = new Uri("https://developer.api.autodesk.com/da/us-east/")
};
//throw the endpoint and HttpMethod here. Could also be HttpMethod.Post/Put/Delete (for your future reference)
var request = new HttpRequestMessage(HttpMethod.Get, "v3/forgeapps/me");
//also maybe try throwing the headers in with the request instead of the client
request.Headers.Add(TokenType, AccessToken);
// send the request, assign to response
HttpResponseMessage response = await client.SendAsync(request);
//then, we can grab the data through the Content
string result = await response.Content.ReadAsStringAsync();
