前后端请求路径如何理解的问题
1 个答案
liangTD 跳转到问题位置 答案时间:2024-06-13 大佬和站长们都不屑回答,那么就自己回答吧!
ajax请求url写法:
开头不写"/“是相对路径,ajax会补全ip+port和项目路径+url,效果: url——>http//:localhost:8080/项目名/url
开头一个"/"相当于是绝对路径,ajax会自动补全为ip+port+请求的url; 效果: /url——>http//:localhost:8080/url
两个"/",ajax只关心协议了;效果: //url——>http://url
至于@GetMapping 写不写"/"其实都是可以的,之前测试应该是前后端都改了,所以不用"/"会报错
如果这理解 有问题,请大家指出!
