HttpClient返回带有正确授权标头的401

Question

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预期响应

VB.Net

Dim objClient As New HttpClient()

objClient.BaseAddress = New Uri("https://www.eventbriteapi.com/v3/")
objClient.DefaultRequestHeaders.Authorization = New AuthenticationHeaderValue("Bearer", "IODVRTRFJ5FVEXZXXXXX")

Dim objResponse As HttpResponseMessage = Await objClient.GetAsync("events/search?organizer.id=77181XXXXX")

If objResponse.IsSuccessStatusCode Then

    Dim strJSON As String = Await objResponse.Content.ReadAsStringAsync
    txtOutput.Text = strJSON

Else

    txtOutput.AppendText(objResponse.ToString + vbCrLf)
    txtOutput.AppendText(objResponse.RequestMessage.ToString + vbCrLf)

End If

objClient.Dispose()

请求

Method: GET, RequestUri: 'https://www.eventbriteapi.com/events/search?organizer.id=77181XXXXX', Version: 1.1, Content: <null>, Headers:
{
  Authorization: Bearer IODVRTRFJ5FVEXZXXXXX
}

响应

Answer 1

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 。

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。

正常的VB.Net代码：

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

我有一个类似的问题。 构建.net应用程序，我正在使用HttpClient类。 我呼叫的网址是“ http”，服务器将其重定向到https。 显然，这会删除标题。 通过邮递员没有发生！

解决方案：使用http S
