AngularJS跨域问题

在springboot的拦截器中添加respone的头信息即可

@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
throws Exception {

//String origin = (String) request.getRemoteHost()+":"+request.getRemotePort();
response.addHeader("Access-Control-Allow-Origin", "*");
//System.out.println("Access-Control-Allow-Origin");
response.addHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
//System.out.println("Access-Control-Allow-Methods");
response.addHeader("Access-Control-Max-Age", "3600");
//System.out.println("Access-Control-Max-Age");
response.addHeader("Access-Control-Allow-Headers", "x-requested-with,Authorization");
//System.out.println("Access-Control-Allow-Headers");
response.addHeader("Access-Control-Allow-Credentials","true");
//System.out.println("Access-Control-Allow-Credentials");
String api_key = request.getParameter("api_key");
String api_secret = request.getParameter("api_secret");
;
if (check(api_key,api_secret)){
return true;
}
response.sendError(400,"api_key or api_secret are error");
return false;
}
 

@Configuration
public class MyWebMvcConfigurer implements WebMvcConfigurer {

@Bean
APIIntercepter apiIntercepter() {
return new APIIntercepter();
}

@Override
public void addInterceptors(InterceptorRegistry registry) {
// 添加一个拦截器，连接以/v1为前缀的 url路径
registry.addInterceptor(loginIntercepter()).addPathPatterns("/admin/**");
registry.addInterceptor(apiIntercepter()).addPathPatterns("/v1/**");

}
}
