angular - ionic native http get 返回类型错误 - 无法读取未定义的属性 'match'

Question

几分钟前，我在最新的 Ionic 中创建了一个新项目。我导入了

import { HTTP } from '@ionic-native/http'

之后我尝试将 GET 请求发送到我的后端应用程序。

meetingsUrl: 'http://localhost:8080/test/all';
 this.http.useBasicAuth('login','password');
    this.http.get(this.meetingsUrl,{}, {'Content-Type':'application/json'})
      .then(data => {
        console.log(data);
      })
      .catch(error => {
        console.log(error);
      });

我正在使用“ionic cordova run browser”命令。我尝试在android上运行，但效果是一样的。

在每种情况下我都会遇到错误:

TypeError: Cannot read property 'match' of undefined

Answer 1

你做错了。您需要设置 headers 详细信息。

请参阅doc

get(url, parameters, headers)

示例 from the doc :

    this.http.get('https://google.com/', {
      id: 12,
      message: 'test'
    }, { Authorization: 'OAuth2: token' }).then(data => {
       console.log(data.status);
       console.log(data.data); // data received by server
       console.log(data.headers);
  })
  .catch(error => {
      console.log(error.status);
      console.log(error.error); // error message as string
      console.log(error.headers);
  });
