ruby-on-rails – 使用Swagger和Foreman Rails服务器获取“Acces

XMLHttpRequest cannot load http://0.0.0.0/api/v1/types.json. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://0.0.0.0:5100' is therefore not allowed access.

我想知道为什么会这样.这是我在index.html中的Swagger配置：

$(function () {
      window.swaggerUi = new SwaggerUi({
      url: "/api-docs.json",dom_id: "swagger-ui-container",supportedSubmitMethods: ['get','post','put','delete'],onComplete: function(swaggerApi,swaggerUi){
        log("Loaded SwaggerUI");

        if(typeof initOAuth == "function") {
          /*
          initOAuth({
            clientId: "your-client-id",realm: "your-realms",appName: "your-app-name"
          });
          */
        }
        $('pre code').each(function(i,e) {
          hljs.highlightBlock(e)
        });
      },onFailure: function(data) {
        log("Unable to Load SwaggerUI");
      },docExpansion: "none"
    });
