一、获取参数【浏览器地址获取参数】…golanggin框架的请求参数一

gin框架的重要性不过多的强调重点就gin使用中的参数传递获取进行梳理文件满足使用需求。

一、获取参数【浏览器地址获取参数】

例如/user/search?usernamezhangsanaddress北京。

URL

】的区别就是DefaultQuery()可以放个默认参数如果没有存参数那么就是使用默认参数

1.1后端代码

(github.com/gin-gonic/ginnet/http

)//

/user/search?usernamezhangsanaddress北京

urlQuery

}1.2浏览器访问从中可以看到我们没有给任何参数后端Query查询的都是为“”

http://127.0.0.1:9000/user/search?usernametomaddressxianusernamejerry

?usernametomaddressxianusernamejerry

1.3.1postman获取参数

请求的参数通过URL路径传递例如/user/search/lisi/北京。

package

(github.com/gin-gonic/ginnet/http

)//

/user/search?usernamezhangsanaddress北京

urlQuery

gin.Default()//两种浏览器地址获取参数的办法//

绑定路由规则

/user/search?usernamezhangsanaddress北京r.GET(/user/search,

urlQueryHandle)//

获取请求URL路径中的参数的方式如下r.GET(/user/search/:username/:address,

paramsPathHandle)//

表单提交POST请求时http常见的传输格式有四种application/json

(json格式)

(text格式)application/x-www-form-urlencode表单默认提交格式application./xml

文件上传)

2.1.1application/x-www-form-urlencode表单默认提交格式

返回结果

2.2.1请求数据application./json(json格式)

2.2.2

(encoding/jsonfmtgithub.com/gin-gonic/ginnet/http

)//

/user/search?usernamezhangsanaddress北京

urlQuery

字符串的形式返回ctx.JSON(http.StatusOK,

gin.H{message:

*multipart.FileHeaderfileHeader,

err

{ctx.JSON(http.StatusInternalServerError,

gin.H{message:

fmt.Sprintf(C:/Users/黑熊精/Pictures/%s,

fileHeader.Filename)//targetFileName

fmt.Sprintf(%s,

ctx.SaveUploadedFile(fileHeader,

targetFileName)if

{ctx.JSON(http.StatusInternalServerError,

gin.H{message:

map[string][]*FileHeader*/form,

err

{ctx.JSON(http.StatusInternalServerError,

gin.H{message:

fmt.Sprintf(C:/Users/黑熊精/Pictures/%d_%s,

file.Filename)err

{ctx.JSON(http.StatusInternalServerError,

gin.H{message:

err.Error(),})return}}ctx.JSON(http.StatusOK,

gin.H{message:

gin.Default()//两种浏览器地址获取参数的办法//

绑定路由规则

/user/search?usernamezhangsanaddress北京r.GET(/user/search,

urlQueryHandle)//

获取请求URL路径中的参数的方式如下r.GET(/user/search/:username/:address,

绑定路由规则--文件上传r.POST(/upload/single,

singleFileUploadHandle)绑定路由规则--多文件上传r.POST(/upload/multi,

监听端口r.Run(:9000)
