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
