Question

我做了一个本机应用程序，使用nodejs和express为后端，启用了cors并在android上运行但是当我开始为ios移植应用程序并在模拟器iphone 6中运行它时运行正常，但是当它运行时我用过superagent给我这个错误。

Error: Request has been terminated
Possible causes: the network is offline, Origin is not allowed by Access-Control-Allow-Origin, the page is being unloaded, etc.

这就是我如何使用superagent

const request = require('superagent');

const req = request[options.method.toLowerCase()](options.uri)
        .set(merge({}, options.headers, options.json ? {'Content-Type': 'application/json'} : {}))
        .query(options.qs ? options.qs : {})
        .send(options.json || options.form || options.formData)
      ;
      const requestId = {};

      api.activeRequests.add(requestId);
      return new Promise((resolve, reject) => {
        req.end((err, res) => {
          console.log({err, res});
          api.activeRequests.delete(requestId);
          if (err || !res.ok) {
            console.log(res);
            const error = res ? (res.body ? res.body : res) : err;
            reject(error);
          } else {
            resolve(res.body);
          }
        });
      });

需要帮助！

这是由于https请求被发布而不是http。因此，截至目前，因为我处于开发者模式，所以允许http到我的特定域。
