我有一个简单的Angular应用,该应用通过以下方式向端点执行发布请求:
login(username:string, password:string){
return this.http.post<String>('localhost:9090/helios-admin/api/auth/login',{
"username": username,
"password":password
});
}
但是抛出CORS策略错误。在我的Spring应用程序中,这是暴露端点的一种,我以这种方式设置了cors映射:
@Configuration
@EnableWebMvc
public class MyWebMvcConfig implements WebMvcConfigurer{
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/api/**")
.allowedOrigins("*")
.allowedMethods("GET","POST", "OPTIONS");
}
}
我遇到了相同的问题,但是在另一个应用程序asked a question中,得到了响应并正确使用了它。现在,此角度项目无法正常工作。我需要更改一些东西吗?
编辑 这是我在Spring Boot中的控制器
@CrossOrigin
@PostMapping(PathConstants.LOGIN_ACTION)
@ApiOperation("Login into Helios administrational console.")
@Override
public ResponseEntity<?> autenticate(@Valid @RequestBody LoginRequest request) {
Authentication auth = authManager
.authenticate(new UsernamePasswordAuthenticationToken(request.getUsername(), request.getPassword()));
SecurityContextHolder.getContext().setAuthentication(auth);
String token = jwtProvider.generateToken(auth);
return ResponseEntity.ok(new JwtAuthResponse(token));
}
更新
问题出在网址中:它需要一个'http://localhost:9090/helios-admin/api/auth/login'
,因此使用http。愚蠢的错误。
现在我有一个新的。
它说:
Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
所以我添加了:
.allowedHeaders("Content-Type", "X-Requested-With", "accept", "Origin", "Access-Control-Request-Method",
"Access-Control-Request-Headers")
.exposedHeaders("Access-Control-Allow-Origin", "Access-Control-Allow-Credentials")
和成角度
this.httpOptions = {
headers: new HttpHeaders({ 'Content-Type': 'application/json',
'Access-Control-Allow-Origin':'*'})
};
return this.http.post<String>('http://localhost:9090/helios-admin/api/auth/login',{
"username": username,
"password":password
}, this.httpOptions).pipe(catchError(this.errorHandler));
但不起作用。

您可以尝试这样
public httpOptions;
login(username:string, password:string){
this.httpOptions = {
headers: new HttpHeaders({ 'Content-Type': 'application/json', 'Authorization': <some data> })
};
return this.http.post<String>(
'localhost:9090/helios-admin/api/auth/login',
{ "username": username, "password":password },
this.httpOptions
);
}

在其余api控制器类方法之前添加 @CrossOrigin 注释。
示例
@CrossOrigin
@RequestMapping(value = "/login", method = {RequestMethod.POST}, consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<ResponseBean> postUserLogin(@RequestBody LoginDTO loginDTO) {
//TODO
}
答案 2 :(得分:0)
您应该向 Spring 添加配置以允许 CORS
我是这样制作的:
java
@Configuration
@EnableWebMvc
public class WebConfig implements WebMvcConfigurer {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**");
}
}
科特林
@EnableWebMvc
class WebConfig : WebMvcConfigurer {
override fun addCorsMappings(registry: CorsRegistry) {
registry.addMapping("/**")
}
}
春天的另一种方式你可以在这里看到。祝你好运
