後端獲取前臺參數的幾種方法

1.前臺通過URL傳遞，後端利用@RequestParam來接收

serverUrl + '/items/refresh?itemSpecIds=' + itemSpecIds

@GetMapping("/refresh")
public void refresh(
        @RequestParam String itemSpecIds) {}

 

2.前臺通過url\傳遞，後臺通過@PathVariable來接收

serverUrl + '/index/sixNewItems/' + rootCatId, {}

@GetMapping("/sixNewItems/{rootCatId}")
public void sixNewItems(
        @PathVariable Integer rootCatId) {}

 

3.前臺通過body中json傳遞，後臺通過@RequestBody來接收

axios.post(serverUrl + '/passport/regist', userBO)

public void PostMapping(@RequestBody UserBO userBO){}
