交易谷歌的oauth2代碼的OAuth2令牌中的ASP.NET

我已經檢查計算器和嘗試了幾種解決方案，但我仍然得到400試圖使一個POST請求谷歌令牌服務器，交易代碼爲的oauth2令牌時。該代碼正在從查詢字符串中正確檢索。我已嘗試使用URL編碼祕密，重定向URL並將請求上的編碼更改爲ASCII。我知道，谷歌是用挑剔的頭，但JSON響應是故意含糊不清，僅返回「錯誤：錯誤的請求」我不能調試什麼是錯的請求。我也嘗試在Chrome REST客戶端中測試發佈請求並收到相同的錯誤。我認爲在頭文件中有一個錯誤或者其他一些格式問題，但是Google沒有返回有用的錯誤代碼。交易谷歌的oauth2代碼的OAuth2令牌中的ASP.NET
