Question

我有一个应用程序，我在其中制作了大约500个同步HTTP请求，我保存了网站的描述和图像。代码片段如下所示，在客户端（使用underscore.js）：

_.each(websiteArray, function (website) {
  // websiteArray has about 500 urls
  Meteor.call("httpRequest", website);
});

在服务器上，使用http-more软件包和CFS-store for images：

Meteor.methods({
  httpRequest: function (website) {
    this.unblock();
    var result = HTTP.get(website.url, {timeout: 30000});
    //save the largest image into CFS-store, description into another collection
  }
});

我遇到了异步调用httpRequest方法的这些错误，并且在同步运行它时仍然可以获取它们，但不太常见：

这些警告仅仅是警告吗？我没有找到适当的程序来发送许多HTTP请求，而不是完全占用服务器。任何帮助将不胜感激。
