在使用以react native编写的Weather应用程序上工作时,在iOS上运行正常时,我在Android上收到``网络请求失败''错误。

javascript - 网络请求失败,Android-LMLPHP

这是提取功能-

componentDidMount: function() {
    navigator.geolocation.getCurrentPosition(
    location => {
      // this variable will contain the full url with the new lat and lon
      var formattedURL = REQUEST_URL + "lat=" + location.coords.latitude + "&lon=" + location.coords.longitude+"&APPID=e5335c30e733fc682907a126dab045fa";

      // this will output the final URL to the Xcode output window
      console.log(location.coords.latitude);
      console.log(location.coords.longitude);
      console.log(formattedURL);

      // get the data from the API
      this.fetchData(formattedURL);

      },
    error => {
      console.log(error);
    });
  },

  // fetchdata takes the formattedURL, gets the json data and
  // sets the apps backgroundColor based on the temperature of
  // the location
  fetchData: function(url) {
    fetch(url)
      .then((response) => response.json())
      .then((responseData) => {

        // set the background colour of the app based on temperature
        var bg;
        var temp = parseInt(responseData.main.temp);
        if(temp < 14) {
          bg = BG_COLD;
        } else if(temp >= 14 && temp < 25) {
          bg = BG_WARM;
        } else if(temp >= 25) {
          bg = BG_HOT;
        }

        // update the state with weatherData and a set backgroundColor
        this.setState({
          weatherData: responseData,
          backgroundColor: bg
        });
      })
      .done();
  },


我在这里也提到了关于stackoverflow的其他问题,但是它们都围绕着将localhost更改为您的本地IP地址(如127.0.0.1)。就我而言,我没有在哪里使用本地主机。

最佳答案

检查模拟器旁边的Android模拟器选项面板,您将有更多选项,然后转到蜂窝网络并检查数据状态和网络类型。尝试将网络类型更改为“完整”,将数据状态更改为“家庭”。尝试使用各种选项来选择网络类型和数据状态,然后检查其是否正常工作...
