[英]HttpClient returns 401 with correct authorisation header
I have been trying for a while now to consume the eventbrite api with vb.net, I am using the HttpClient
to consume the api however it only returns a HTTP 401 Unathorised
when I call the same method with the same headers using postman it returns the expected response with a HTTP 200 OK
我一直在尝试使用vb.net来使用eventbrite api,我正在使用HttpClient
来使用api,但是当我使用HTTP 401 Unathorised
调用具有相同标头的相同方法时,它仅返回HTTP 401 Unathorised
。 HTTP 200 OK

The reason I was getting the 401 Unauthorized
was because when i was calling the api originally I was querying https://www.eventbriteapi.com/v3/events/search?organizer.id=77181XXXXX
. 我获得401 Unauthorized
的原因是,当我最初调用api时,我正在查询https://www.eventbriteapi.com/v3/events/search?organizer.id=77181XXXXX
。
This URL is not valid and should be https://www.eventbriteapi.com/v3/events/search/?organizer.id=77181XXXXX
(note the extra / after search) 该URL无效,应为https://www.eventbriteapi.com/v3/events/search/?organizer.id=77181XXXXX
(请注意多余的/搜索后)
Eventbrite automatically redirected me to the correct URL however it lost the authentication header and thus was unauthorized. Eventbrite自动将我重定向到正确的URL,但是它丢失了身份验证标头,因此未经授权。
Dim objClient As New HttpClient()
Try
objClient.BaseAddress = New Uri("https://www.eventbriteapi.com/v3/")
objClient.DefaultRequestHeaders.Authorization = New AuthenticationHeaderValue("Bearer", Context.EventBriteApiToken)
Dim objResponse As HttpResponseMessage = Await objClient.GetAsync("users/" + Context.EventBriteUserId + "/owned_events/?page=" + intPage.ToString)
objResponse.EnsureSuccessStatusCode() '** Throws exception
Dim strJSON As String = Await objResponse.Content.ReadAsStringAsync
Return JsonConvert.DeserializeObject(Of EventBrite.EventSearchResponse)(strJSON)
Catch ex As Exception
Throw ex
Finally
objClient.Dispose()
End Try
I had a similar issue. 我有一个类似的问题。 Building .net application and I was using the HttpClient class. 构建.net应用程序,我正在使用HttpClient类。 The url I was calling was "http" and the server redirects it to https. 我呼叫的网址是“ http”,服务器将其重定向到https。 Apparently this drops the headers. 显然,这会删除标题。 Didnt happen through postman !! 通过邮递员没有发生!
