以下示例使用自定义结构

type StructA struct { FieldA string `form:"field_a"`} type StructB struct { NestedStruct StructA FieldB string `form:"field_b"`} type StructC struct { NestedStructPointer *StructA FieldC string `form:"field_c"`} type StructD struct { NestedAnonyStruct struct { FieldX string `form:"field_x"` } FieldD string `form:"field_d"`} func GetDataB(c *gin.Context) { var b StructB c.Bind(&b) c.JSON(200, gin.H{ "a": b.NestedStruct, "b": b.FieldB, })} func GetDataC(c *gin.Context) { var b StructC c.Bind(&b) c.JSON(200, gin.H{ "a": b.NestedStructPointer, "c": b.FieldC, })} func GetDataD(c *gin.Context) { var b StructD c.Bind(&b) c.JSON(200, gin.H{ "x": b.NestedAnonyStruct, "d": b.FieldD, })} func main() { 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

type StructX struct { X struct {} `form:"name_x"` // HERE have form} type StructY struct { Y StructX `form:"name_y"` // HERE have form} type StructZ struct { Z *StructZ `form:"name_z"` // HERE have form}

总之，现在只支持现在没有form标签的自定义结构
