XMLHttpRequest 被 CORS 策略注释 @CrossOrigin 阻止

Question

从源“https://mysuite.ru”访问“http://localhost:8080/api/auth/signup”的 XMLHttpRequest 已被 CORS 策略阻止：对预检请求的响应未通过访问控制检查：预检请求不允许重定向。

http.cors().and()
            .exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
            .authorizeRequests()
            .antMatchers("/admin").hasRole("ADMIN")
            .antMatchers("/").permitAll()
            .antMatchers("/favicon.ico").permitAll()
            .antMatchers("/static/**").permitAll()
            .antMatchers("/manifest.json").permitAll()
            .antMatchers("/logo192.png").permitAll()
            .antMatchers("/api/auth/**").permitAll()
            .antMatchers("/api/test/**").permitAll()
            .anyRequest().authenticated();

    http.addFilterBefore(authenticationJwtTokenFilter(), UsernamePasswordAuthenticationFilter.class);




@RestController
@RequestMapping("/api/auth")
@CrossOrigin(origins = "*", maxAge = 3600)
public class AuthController {

通过 nginx 重定向

server {
    listen       443 ssl;
    server_name   is my address.ru;

    ssl_certificate      C:/ssl/ip.crt;
    ssl_certificate_key  C:/ssl/ip.key;

    ssl_session_cache    shared:SSL:1m;
    ssl_session_timeout  5m;

    ssl_ciphers  HIGH:!aNULL:!MD5;
    ssl_prefer_server_ciphers  on;

    location / {
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header X-NginX-Proxy true;
      proxy_pass        http://localhost:8080;
      proxy_set_header  Host $http_host;
      proxy_redirect off;
    }
}

更新

请求标头：

Accept: application/json, text/plain, */*

Modified-Since,Cache-Control,Content-Type,Range
Access-Control-Allow-Methods: GET, POST, OPTIONS

Access-Control-Expose-Headers: Content-Length,Content-Range
Content-Type: application/json;charset=UTF-8

在 nginx 中添加：

location / {
    
    if ($request_method = 'OPTIONS') {
    add_header 'Access-Control-Allow-Origin' '*';
    add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
     #
     # Custom headers and headers various browsers *should* be OK with but aren't
     #
     add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';
     #
     # Tell client that this pre-flight info is valid for 20 days
     #
     add_header 'Access-Control-Max-Age' 1728000;
     add_header 'Content-Type' 'text/plain; charset=utf-8';
     add_header 'Content-Length' 0;
     return 204;
     }
     if ($request_method = 'POST') {
     add_header 'Access-Control-Allow-Origin' '*' always;
     add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS' always;
     add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range' always;
     add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range' always;
     }
     if ($request_method = 'GET') {
     add_header 'Access-Control-Allow-Origin' '*' always;
     add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS' always;
     add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range' always;
     add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range' always;
    }
    
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $http_host;
      proxy_pass http://localhost:8080;
    }

还没有结果

Answer 1

尝试将methods 属性添加到@CrossOrigin。用于注释方法时，支持的方法与方法映射到的方法相同，但由于您在类级别使用它，因此可能需要按如下方式指定它们：

@CrossOrigin(origins = "*", maxAge = 3600, methods = {RequestMethod.GET, RequestMethod.POST} ) // Just an example

Answer 2

尝试将 @CrossOrigin 注释替换为

 @CrossOrigin(value = "https://mysuite.ru", allowCredentials = "true")

不要使用“*”作为来源，而是使用“https://mysuite.ru”。
