解析雲端httpRequest未返回響應

我在瀏覽器中從js調用了我的Parse Cloud函數。我只是在做一個測試。我正在嘗試撥打http://api.geonames.org進行GET調用。如果我在瀏覽器中以http://api.geonames.org/citiesJSON?north=44.1&south=-9.9&east=-22.4&west=55.2&lang=de&username=demo執行它，它確實有效。它返回：解析雲端httpRequest未返回響應

而如果我在雲代碼執行它：我在本地的機器

Parse.Cloud.define("testRequest", function(request , response){ 
    Parse.Cloud.httpRequest({ 
     url: 'http://api.geonames.org/citiesJSON', 
     params: { 
      'north' : '44.1', 
      'south' : '-9.9', 
      'east' : '-22.4', 
      'west' : '55.2', 
      'lang' : 'de', 
      'username' : 'demo' 
     }, 
     success:function(httpResponse){ 
      console.log(httpResponse.text); 
      response.success("success from response.success>>>>"); 
      console.log('httpResponse->'+ httpResponse.response +' <<<'); 
      console.log('data>>'+httpResponse.data); 
     }, 
     error:function(httpResponse){ 
      console.error('Request failed with response code ' + httpResponse.status); 
      response.error(httpResponse.status); 
     }, 
    }); 
});

隨着腳本：

<script type="text/javascript"> 
    Parse.initialize("KEY", "KEY"); 



     Parse.Cloud.run('testRequest', {}, { 
      success: function(result) { 
      alert(result.httpRequest+"<----RESULT!") 
      // result is 'Hello world!' 
      }, 
      error: function(error) { 
      alert("Something went wrong"+error.message); 
      } 
     }); 
    </script>

它返回200個狀態，但沒有數據。我確信我部署了我的代碼，並且我在Parse.com的Cloud Code選項卡中看到了最新的代碼，因此我確實不會在雲上運行舊代碼。

您是否知道如何從Cloud Code中正確進行GET調用？關於這個主題的任何幫助或幫助我糾正我的代碼中的任何錯誤，非常感謝！

如果它正是你正在運行的代碼，CloudCode函數返回一個字符串'response.success >>>>'成功，對不對？但是你的JavaScript代碼試圖從字符串中獲得'httpRequest'。 – iForests

你是什麼意思？對不起，我聽不懂......你是說我不應該從response.success返回'成功>>>>'？ – idelara

是的。我認爲你應該'response.success（httpResponse.text）;'和'alert（result）;'。瀏覽器會通知Json'{「geonames」：[{「fcodeName」：「ca ...'now。 – iForests

您應該CloudCode通過

response.success(httpResponse.text);

返回的數據，並使用這些數據在JavaScript這樣

Parse.Cloud.run('testRequest', {}, { 
    success: function(result) { 
     alert(result); 
    } 
});

現在，您將看到結果。
