Python和Spring Boot项目如何配置ajax跨域

 Python项目配置ajax跨域：

class BaseHandler(tornado.web.RequestHandler):
    # 解决跨域问题
    def set_default_headers(self):
        self.set_header('Access-Control-Allow-Origin', '*')
        self.set_header('Access-Control-Allow-Headers', '*')
        self.set_header('Access-Control-Max-Age', 1000)
        # self.set_header('Content-type', 'application/json')
        self.set_header('Access-Control-Allow-Methods', 'POST, GET, OPTIONS')
        self.set_header('Access-Control-Allow-Headers', #'*')
                        'authorization, Authorization, Content-Type, Access-Control-Allow-Origin, '
                        'Access-Control-Allow-Headers, X-Requested-By, Access-Control-Allow-Methods')
        

# 正常的Python后台请求代码
# class TestHandler(tornado.web.RequestHandler):
# 配置跨域的后台请求代码
class TestHandler(BaseHandler):
    def get(self):
        self.write("测试跨域")

Spring Boot项目配置ajax跨域：

package com.test.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;


/**

 * @description 解决前后台对接跨域问题
 * 在springboot项目的config目录下添加该类，即可实现ajax跨域
 */
@Configuration
public class CorssConfig {
    // 设置允许跨域的源
    private static String[] originsVal = new String[]{
            "127.0.0.1:8085",
            "localhost:8080",
//            "google.com"
    };

    /**
     * 跨域过滤器
     *
     * @return
     */
    @Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        this.addAllowedOrigins(corsConfiguration);
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedMethod("*");
        corsConfiguration.addAllowedOrigin("*");
        source.registerCorsConfiguration("/**", corsConfiguration);
        return new CorsFilter(source);
    }

    private void addAllowedOrigins(CorsConfiguration corsConfiguration) {
        for (String origin : originsVal) {
            corsConfiguration.addAllowedOrigin("http://" + origin);
            corsConfiguration.addAllowedOrigin("https://" + origin);
        }
    }
}
