解決Axios發送POST傳參后台接收為null問題

1.前端請求格式                                                            

//用這種傳參
var params = new URLSearchParams()
params.append('name', '123')//發送post請求
axios.post("api接口",params,{
    //必須加請求頭
    headers: {
        'Content-Type': 'application/json'
    }
}).then(function(res){ //請求回調函數
    console.log(res)
})    

 

 

2.后端接收格式                                                           

 

@PostMapping("/test") 
//這里要加RequestBody注解來接收參數
public ResponseResult faceRecognzeLogin(@RequestBody String name) {
    //...
}
