我正在尝试使用 OAuth2 和“已安装的应用程序”流程(获取身份验证代码,然后请求 token )对我的应用程序进行身份验证。我收到了 400 bad request error
在 GetResponse() 行上请求 token 时。我的代码如下:
Public Sub New()
Dim tokenRequest As WebRequest =
WebRequest.Create("https://accounts.google.com/o/oauth2/token")
Dim requestString As String = "code=<auth-code>" _
& "&client_id=<client_id>" _
& "&client_secret=<client_secret>" _
& "&redirect_uri=http://localhost" _
& "&grant_type=authorization_code"
byteArray = StrToByteArray(System.Web.HttpUtility.UrlEncode(requestString))
tokenRequest.Credentials = CredentialCache.DefaultCredentials
tokenRequest.Method = "POST"
tokenRequest.ContentLength = byteArray.Length
tokenRequest.ContentType = "application/x-www-form-urlencoded"
Dim dataStream As Stream = tokenRequest.GetRequestStream()
dataStream.Write(byteArray, 0, byteArray.Length)
dataStream.Close()
Console.WriteLine("Getting response...")
'Get response
Try
Dim response As WebResponse = tokenRequest.GetResponse()
Console.WriteLine(CType(response, HttpWebResponse).StatusDescription)
Dim data As Stream = response.GetResponseStream
Array.Resize(byteArray, 4096)
Array.Clear(byteArray, 0, byteArray.Length)
data.Read(byteArray, 0, byteArray.Length)
response.Close()
Catch wex As WebException
Console.WriteLine("ERROR! : ")
Console.WriteLine(wex.Message)
Console.WriteLine(wex.Status)
Console.WriteLine(wex.Data)
Console.WriteLine(wex.InnerException.Message)
Console.WriteLine(wex.HelpLink)
End Try
End Sub
错误的具体情况如下:
The remote server returned an error: (400) Bad Request.

System.Collections.ListDictionaryInternal
System.NullReferenceException: Object reference not set to an instance of an obj

我看过 Google GetAccessToken : Bad Request 400和 Google GData .Net OAuthUtil.GetAccessToken 400 Bad Request但还没有找到适合此代码的解决方案。我已经检查了所有建议的解决方案并实现了它们,但到目前为止还没有运气。
最佳答案
看起来您没有为参数设置值 授权码 , client_id 或 client_secret .
您可以使用 curl 命令调试这些参数,看看这是否是问题的根源。例如
curl -X POST -d "code=<auth-code>&client_id=<client_id>&client_secret=<client_secret>"&grant_type=authorization_code" http://localhost:8000/auth/token
