vue + axios发送post请求,403错误的解决

前端是vue2.0,网络请求用的是axios,后端是springboot2.0
用axios向后端发送post请求,结果得到一个403无权限的错误,莫名其妙啊,我明明发送的是post请,但在chrome的调试里看到的却是options。

意思就是跨域请求无权限了。
在segmentfault网站上,这位仁兄的解释非常正确

到这里,只要在后端设置options响应支持即可!
后端代码如下

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;


@SpringBootApplication
public class Starter {

    public static void main(String[] args) {
        SpringApplication.run(Starter.class, args);
    }

    private CorsConfiguration buildConfig() {
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedOrigin("*");
        corsConfiguration.addAllowedMethod("*");
        corsConfiguration.setAllowCredentials(true);
        return corsConfiguration;
    }

    @Bean
    public CorsFilter corsFilter() {
        System.out.println("=============== 设置跨域过滤器 ================");
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", buildConfig());
        return new CorsFilter(source);
    }

}
