gin使用自定义结构绑定表单数据的示例代码
以下示例使用自定义结构
typeStructAstruct{
FieldAstring`form:"field_a"`
}
typeStructBstruct{
NestedStructStructA
FieldBstring`form:"field_b"`
}
typeStructCstruct{
NestedStructPointer*StructA
FieldCstring`form:"field_c"`
}
typeStructDstruct{
NestedAnonyStructstruct{
FieldXstring`form:"field_x"`
}
FieldDstring`form:"field_d"`
}
funcGetDataB(c*gin.Context){
varbStructB
c.Bind(&b)
c.JSON(200,gin.H{
"a":b.NestedStruct,
"b":b.FieldB,
})
}
funcGetDataC(c*gin.Context){
varbStructC
c.Bind(&b)
c.JSON(200,gin.H{
"a":b.NestedStructPointer,
"c":b.FieldC,
})
}
funcGetDataD(c*gin.Context){
varbStructD
c.Bind(&b)
c.JSON(200,gin.H{
"x":b.NestedAnonyStruct,
"d":b.FieldD,
})
}
funcmain(){
r:=gin.Default()
r.GET("/getb",GetDataB)
r.GET("/getc",GetDataC)
r.GET("/getd",GetDataD)
r.Run()
}
运行示例：
$curl"http://localhost:8080/getb?field_a=hello&field_b=world"
{"a":{"FieldA":"hello"},"b":"world"}
$curl"http://localhost:8080/getc?field_a=hello&field_c=world"
{"a":{"FieldA":"hello"},"c":"world"}
$curl"http://localhost:8080/getd?field_x=hello&field_d=world"
{"d":"world","x":{"FieldX":"hello"}}
注意：不支持以下样式结构
typeStructXstruct{
Xstruct{}`form:"name_x"`//HEREhaveform
}
typeStructYstruct{
YStructX`form:"name_y"`//HEREhaveform
}
typeStructZstruct{
Z*StructZ`form:"name_z"`//HEREhaveform
}
总之，现在只支持现在没有form标签的自定义结构
