我正在尝试使用webapi
api:-

@CrossOrigin(origins="http://IP:4200")
    @RestController
    @RequestMapping("/api/v1")
    public class BasicAuthController {
            @PostMapping(path = "/authenticate")
            public ResponseEntity<?> createAuthenticationToken(@RequestBody JwtRequest authenticationRequest) {

                log.info("end createAuthenticationToken method");
                return ResponseEntity.ok(userDetailsinfo);
            }
    }

client:-

authenticationService(formData) {
      return this.http.post<any>('/api/v1/authenticate',   formData).pipe(map((res) => {
       debugger;
    }));  
  }

proxy.config.json文件

{
    "/api": {
        "target": "http://IP:8080",
        "secure": false,
        "changeOrigin": true
    }
}

我已经使用 ng-serve
