如何解决看跌期权的 401 未经授权错误

Question

我尝试通过

httpwebrequest

put 调用更新值，但收到 401 未经授权的错误。如果我在邮递员或招摇中测试它工作正常并且更新成功。下面是我的代码：

Dim client As HttpWebRequest = DirectCast(HttpWebRequest.Create(apiUrl), HttpWebRequest)
client.Method = "PUT"
client.Headers.Add("Authorization", "Bearer ")
client.ContentType = "application/json"
client.ContentLength = byteData.Length

Dim postreqstream As Stream = client.GetRequestStream()
postreqstream.Write(byteData,0, byteData.Length)

Dim postresponse As HttWebResponse
postresponse = DirectCast(client.GetResponse, HttpWebResponse)

Dim postreader as New StreamReader(postresponse.GetResponseStream())

Dim thePage As String = postreader.ReadToEnd

Answer 1

只需更新线路

client.Headers.Add("Authorization", "Bearer ")

到

client.Headers.Add("Authorization", "Bearer " + token)

而不是

token

，您应该添加不带“Bearer”字样的不记名令牌。
