go参数获取

go 参数获取方法：

1. a. body form-data b. (post form params)

examNum      := cont.PostForm("examNum")
realName     := cont.PostForm("realName")
identityCard := cont.PostForm("identityCard")
fmt.Printf("1. body form-data cont.PostForm %v @ %v @ %v \n", examNum, realName, identityCard)

2. a. (body form-data) b. (post form params) c. get form params

examNum  = cont.Request.FormValue("examNum")
realName = cont.Request.FormValue("realName")
identityCard = cont.Request.FormValue("identityCard")
fmt.Printf("1. (body form-data) 2. (post params) cont.Request.FormValue %v @ %v @ %v \n", examNum, realName, identityCard)

3. a. (post form params)

examNum  = cont.Request.PostFormValue("examNum")
realName = cont.Request.PostFormValue("realName")
identityCard = cont.Request.PostFormValue("identityCard")
fmt.Printf("cont.Request.PostFormValue %v @ %v @ %v \n", examNum, realName, identityCard)

4. FORM GET请求

examNum  = cont.Query("examNum")
realName = cont.Query("realName")
identityCard = cont.Query("identityCard")
fmt.Printf("2. (post params) cont.Query %v @ %v @ %v \n", examNum, realName, identityCard)

5. 测试 form get/post 参数都获取不到

examNum  = cont.Param("examNum")
realName = cont.Param("realName")
identityCard = cont.Param("identityCard")
fmt.Printf("cont.Param %v @ %v @%v \n", examNum, realName, identityCard)
