最近使用http请求测试接口,传参数格式给了自己狠狠大的困惑今天花时间总结下。

当你的controller使用post接收请求的时候 传参一般是 封装类 和封装的对象 需要注解@RequestBody @RequestParam 才能接收到json的参数 不然是接收不到的比如

两个接口

@ApiOperation(value = "登录")
@RequestMapping(value = "/login",method = RequestMethod.POST)
@ResponseBody
public ViewResult login(@RequestBody UserRequest userRequest) {
    return userService.login(userRequest);
}
    

@ApiOperation(value = "登录")
@RequestMapping(value = "/login",method = RequestMethod.POST)
@ResponseBody
public ViewResult login(UserRequest userRequest) {
    return userService.login(userRequest);
}

http请求 当你的idea使用http cliect发请求时

第一个接口接收到参数 第二个可以接收不到参数

###
POST http://localhost:6688/gzl-oauth/oauth/login
Content-Type: application/json
Authorization:

{
  "account": "gzlwork",
  "password": "gzlwork"

}

第一个接口接收不到参数 第二个可以接收到参数

###
POST http://localhost:6688/gzl-oauth/oauth/login
Content-Type: application/x-www-form-urlencoded

account=gzlwork&password=gzlwork


###
POST http://localhost:6688/gzl-oauth/oauth/login?account=gzlwork&password=gzlwork
Content-Type: application/x-www-form-urlencoded


这两种发送参数的方式没有区别


当你传参数时 封装类单个参数的时候

@ApiOperation(value = "登录")
@RequestMapping(value = "/login",method = RequestMethod.POST)
@ResponseBody
public ViewResult login(@RequestParam(name) String name) {
    return userService.login(name);
}
    

@ApiOperation(value = "登录")
@RequestMapping(value = "/login",method = RequestMethod.POST)
@ResponseBody
public ViewResult login(String name) {
    return userService.login(name);
}

接口都可以接收到参数的,

###
POST http://localhost:6688/gzl-oauth/oauth/loginForm
Content-Type: application/x-www-form-urlencoded

{

}

Content-Type: application/json 模式接口实现时需要添加@RequestBody @RequestParam 注解 接口才能接收到http传的json数据

如果没有添加注解 默认的是Content-Type: application/x-www-form-urlencoded 表单提交 我们也能注意到 当使用@RequestParam注解的时候,使用表单提交参数也是能接收到参数的
