Ionic 2 http.get android 500

Question

我嘗試在離子2中創建一個http.get。它在ios上工作正常，但不能在android中工作。

checkHTTP() { 
    console.log('checkHTTP'); 
    return this.http.get('http://apiv3.iucnredlist.org/api/v3/version', {}, {}) 
    .then((data) => { 
     console.log(data); 
    }) 
    .catch((error) => { 
     console.log(error); 
    }) 
} 

這是導致安卓

Object {status: 500, error: "There was an error with the request"} error : "There was an error with the request" status : 500

下面是離子

Answer 1

一些相關信息，答案很簡單。我的測試設備失去了互聯網連接。但WLAN狀態看起來很正常:-( 但是有點奇怪，我認爲500意味着服務器錯誤
