内容类型为Zuul的网关错误：多部分/表单数据API

Question

我们将项目移至春季启动2，并在API中收到了CORS错误，该错误发送了 Content-Type：multipart / form-data 。 在旧版本上运行正常。

对于CORS，我们将其禁用，并添加以下代码。

@Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurerAdapter() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**")
                        .allowedMethods("GET", "POST", "PUT", "DELETE", "HEAD", "OPTIONS")
                        .exposedHeaders("Content-Disposition");

            }
        };
    }

所有API在旧版本上都可以正常使用，但是现在当我们在春季启动2中移动时， Content-Type：application / json 可以正常使用的api。 但是在下面的API中抛出cors错误。

  

在以下位置访问XMLHttpRequest   来源的“ http：// {MyIP}：8080 / users / v1 / admin / uploadArticleData”   “ http：// {MyIP}：3000”已被CORS政策阻止：否   请求中存在“ Access-Control-Allow-Origin”标头   资源。

OPTION API：-

Post API：-

与我的Zuul网关有关的某些问题，在调用 Content-Type：multipart / form-data; API时，其引发以下错误。 错误：-
