Content-Type: application/x-www-form-urlencoded;charset=utf-8 

這應該是最常見的 POST 提交資料的方式了。瀏覽器的原生 form 表單，如果不設定 enctype 屬性，那麼最終就會以 application/x-www-form-urlencoded 方式提交資料。 

curl 測試介面地址是否通不通，這個命令和postman差不多，比輕量，也會返回請求的結果

curl https://地址  -X POST -d "引數名=引數值&引數名=引數值&引數名=引數值"

加請求格式  application/x-www-form-urlencoded

curl  地址  -X  POST  -H "Content-Type:application/x-www-form-urlencoded" -d "引數名=引數值&引數名=引數值&引數名=引數值"
