備忘：gin.Context與axios傳遞JSON數(shù)據(jù)的綁定

gin的控制器：
type ExampleService struct { UserName String Password String } func (example
*ExampleService) LoginCheck(c *gin.Context) bool { c.Bind(&example)
............ }前端應(yīng)該寫：this.axios.post("login.html", { UserName: this.username,
//這里對應(yīng)struct的成員名 Password: this.password })
還有一種更輕量靈活的寫法:

func LoginCheck(c *gin.Context) bool { var param struct { Username string
`json:"username" binding:"required"` Password string `json:"password"
binding:"required"` } c.Bind(¶m) ............................
前端照舊




劃重點(diǎn): 結(jié)構(gòu)體成員變量名首字母必須大寫!!!




補(bǔ)充:

當(dāng)綁定的成員為int或者int32,int64類型時,前端如果傳入的值為0,會報如下錯誤:

[GIN-debug] [WARNING] Headers were already written. Wanted to override status
code 400 with 200


且前端會報錯誤:Failed to load resource: the server responded with a status of 400
(Bad Request)

導(dǎo)致不正常.

解決辦法1: 避免設(shè)計(jì)0值;

解決辦法2: 去掉以下結(jié)構(gòu)體的 binding:"required"



var json struct { ????????Status int64 `json:"status" binding:"required"`
????} ????c.Bind(&json)
