前言：
刚开始请求的时候报 CORS 错误，通过前端项目配置后算是解决了，然后，又开始了新的报错 403 ERR_BAD_REQUEST。但是 GET 请求是正常的。
后端的 Controller 接口代码如下：
@PostMapping(value = "/login2")
@ResponseBody
public LoginReq login2(@RequestBody LoginReq req, HttpServletRequest servletRequest, HttpServletResponse response) {
System.out.println("---- login2 ----- userName = " + req.getUserName());
// // 设置js请求跨域解决
response.addHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
response.setHeader("Access-Control-Allow-Methods", "GET, PUT, OPTIONS, POST");
String userCode = servletRequest.getHeader("userCode");
String accessToken = servletRequest.getParameter("accessToken");
System.out.println("---- login2 --------------- accessToken = " + accessToken+" , userCode = " + userCode);
String user = JSONObject.toJSONString(req);
System.out.println("---- login2 ----- user = " + user);
System.out.println("---- login2 ----- birthday = " + req.getBirthday());
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm");
Date date = null;
try {
date = simpleDateFormat.parse(simpleDateFormat.format(req.getBirthday()));
} catch (ParseException e) {
e.printStackTrace();
}
System.out.println("date = " + simpleDateFormat.format(date));
req.setBirthday(new Date());
// 获取 cookie
Cookie[] cookies = servletRequest.getCookies();
if (cookies != null && cookies.length > 0) {
for (Cookie cookie : cookies) {
String name = cookie.getName();
String value = cookie.getValue();
System.out.println("cookie >> name = " + name + " , value = " + value);
}
}
if (req.getUserName().isEmpty() || req.getPwd().isEmpty()) {
throw new RuntimeException("userName or pwd is empty");
}
return req;
}
前端的调用代码如下：
axios({
method: 'POST',
url: 'login/demo_war_exploded/login2',
data: JSON.stringify(
{
'userName':"朱",
'pwd':"pass1234!",
'birthday':"2022-12-06"
}),
headers: {
'Content-Type' : 'application/json'
}
}).then(response => {
console.log(response)
}).catch(function (error) {
console.log(error)
})
解决跨域问题的前端配置：
proxy: {
"/login" :{
target: "http://localhost:8180/",
changeOrigin: true,
//ws: true,//websocket支持
secure: false,
pathRewrite: {
"^/login": ""
},
}
}
403 报错如下图：
网上搜索了一堆都不行，各种五花八门的答案，对我来说都是无效的。
直到后面问了一个前端的同事，他让我在配置跨域的地方加一行配置，结果就 OK 啦，
proxy: {
//配置多个跨域
"/login" :{
target: "http://localhost:8180/",
changeOrigin: true,
//ws: true,//websocket支持
secure: false,
pathRewrite: {
"^/login": ""
},
// 后面新增的配置
onProxyReq(proxyReq) {
proxyReq.removeHeader('origin')
}
}
},
最后，成功的截图如下：
