frp使用過程中會出現各種錯誤信息，有些朋友不太清楚，打算記錄一些常見的錯誤返回代碼，這里介紹一下frpc客戶端[W] [control.go:111] login to server failed: authorization failed的錯誤處理方法：
frpc登錄成功正確的返回信息應該是：
C:\Users\Administrator>C:\Windows\ad\frpc.exe -c C:\Windows\ad\frpc.ini 2018/04/28 15:32:36 [I] [proxy_manager.go:299] proxy removed: [] 2018/04/28 15:32:36 [I] [proxy_manager.go:309] proxy added: myname.chuantou] 2018/04/28 15:32:36 [I] [proxy_manager.go:332] visitor removed: [] 2018/04/28 15:32:36 [I] [proxy_manager.go:341] visitor added: [] 2018/04/28 15:32:36 [I] [control.go:242] [1f64bfaeccf6cb39] login to erver success, get run id [1f64bfaeccf6cb39], server udp port [7001] 2018/04/28 15:32:37 [I] [control.go:167] [1f64bfaeccf6cb39] [myname.xxorg] start proxy success
frpc登錄失敗時返回login to server failed: authorization failed
C:\Users\Administrator>C:\Windows\ad\frpc.exe -c C:\Windows\ad\frpc.ini 2018/04/28 15:31:31 [I] [proxy_manager.go:299] proxy removed: [] 2018/04/28 15:31:31 [I] [proxy_manager.go:309] proxy added: [myname.chuantou] 2018/04/28 15:31:31 [I] [proxy_manager.go:332] visitor removed: [] 2018/04/28 15:31:31 [I] [proxy_manager.go:341] visitor added: [] 2018/04/28 15:31:31 [E] [control.go:232] authorization failed 2018/04/28 15:31:31 [W] [control.go:111] login to server failed: authorization failed authorization failed
login to server failed: authorization failed錯誤的原因及處理辦法
login to server failed: authorization failed是因為token錯誤導致的，可以檢查token的值是不是正確，比如本站提供的免費frp內網穿透服務器的token值是 www.chuantou.org ,另外一種錯誤的原因是0.17.0以前的版本沿用了特權模式時候的寫法privilege_token = www.chuantou.org ，從0.17.0開始使用token = www.chuantou.org ，所以檢查是不是token的配置項名稱錯誤了。
