解决Axios发送POST传参后台接收为null问题

1.前端请求格式                                                            

//用这种传参
var params = new URLSearchParams()
params.append('name', '123')//发送post请求
axios.post("api接口",params,{
    //必须加请求头
    headers: {
        'Content-Type': 'application/json'
    }
}).then(function(res){ //请求回调函数
    console.log(res)
})    

 

 

2.后端接收格式                                                           

 

@PostMapping("/test") 
//这里要加RequestBody注解来接收参数
public ResponseResult faceRecognzeLogin(@RequestBody String name) {
    //...
}
