解析雲httpRequest不返回響應

Question

我正在從瀏覽器中的js調用我的Parse Cloud函數。 我只是在做測試。 我正在嘗試對http://api.geonames.org進行GET調用。 如果我以http://api.geonames.org/citiesJSON?north=44.1&south=-9.9&east=-22.4&west=55.2&lang=de&username=demo在瀏覽器中執行它，則它確實可以正常工作。 它返回：

{"geonames":[{"fcodeName":"capital of a political entity","toponymName":"Mexico City","countrycode":"MX","fcl":"P","fclName":"city, village,...","name":"Mexiko-Stadt","wikipedia":"en.wikipedia.org/wiki/Mexico_City","lng":-99.12766456604,"fcode":"PPLC","geonameId":3530597,"lat":19.428472427036,"population":12294193},{"fcodeName":"capital of a political entity","toponymName":"Beijing","countrycode":"CN","fcl":"P","fclName":"city, village,...","name":"Peking","wikipedia":"en.wikipedia.org/wiki/Beijing","lng":116.397228240967,"fcode":"PPLC","geonameId":1816670,"lat":39.9074977414405,"population":11716620},{"fcodeName":"capital of a political entity","toponymName":"Manila","countrycode":"PH","fcl":"P","fclName":"city, village,...","name":"Manila","wikipedia":"en.wikipedia.org/wiki/Manila","lng":120.9822,"fcode":"PPLC","geonameId":1701668,"lat":14.6042,"population":10444527},{"fcodeName":"capital of a political entity","toponymName":"Dhaka","countrycode":"BD","fcl":"P","fclName":"city, village,...","name":"Dhaka","wikipedia":"en.wikipedia.org/wiki/Dhaka","lng":90.40743827819824,"fcode":"PPLC","geonameId":1185241,"lat":23.710395616597037,"population":10356500},{"fcodeName":"capital of a political entity","toponymName":"Seoul","countrycode":"KR","fcl":"P","fclName":"city, village,...","name":"Seoul","wikipedia":"en.wikipedia.org/wiki/Seoul","lng":126.9784,"fcode":"PPLC","geonameId":1835848,"lat":37.566,"population":10349312},{"fcodeName":"capital of a political entity","toponymName":"Jakarta","countrycode":"ID","fcl":"P","fclName":"city, village,...","name":"Jakarta","wikipedia":"en.wikipedia.org/wiki/Jakarta","lng":106.84513092041016,"fcode":"PPLC","geonameId":1642911,"lat":-6.214623197035775,"population":8540121},{"fcodeName":"capital of a political entity","toponymName":"Tokyo","countrycode":"JP","fcl":"P","fclName":"city, village,...","name":"Tokio","wikipedia":"de.wikipedia.org/wiki/Tokyo","lng":139.69171,"fcode":"PPLC","geonameId":1850147,"lat":35.6895,"population":8336599},{"fcodeName":"capital of a political entity","toponymName":"Taipei","countrycode":"TW","fcl":"P","fclName":"city, village,...","name":"Taipeh","wikipedia":"de.wikipedia.org/wiki/Taipei","lng":121.531846,"fcode":"PPLC","geonameId":1668341,"lat":25.047763,"population":7871900},{"fcodeName":"capital of a political entity","toponymName":"Bogotá","countrycode":"CO","fcl":"P","fclName":"city, village,...","name":"Bogotá","wikipedia":"en.wikipedia.org/wiki/Bogot%C3%A1","lng":-74.08175468444824,"fcode":"PPLC","geonameId":3688689,"lat":4.609705849789108,"population":7674366},{"fcodeName":"capital of a political entity","toponymName":"Hong Kong","countrycode":"HK","fcl":"P","fclName":"city, village,...","name":"Hong Kong","wikipedia":"en.wikipedia.org/wiki/Hong_Kong","lng":114.157691001892,"fcode":"PPLC","geonameId":1819729,"lat":22.2855225817732,"population":7012738}]}

而如果我在雲代碼中將其執行為：

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);
        }, 
    });
});

在我的本地計算機上使用以下腳本：

<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狀態，但沒有數據。 我確保已部署代碼，並且在Parse.com的“雲代碼”選項卡中看到了最新的代碼，因此絕對不能在雲上運行舊代碼。

您知道如何正確地從Cloud Code進行成功的GET調用嗎？ 非常感謝您提供有關此主題的任何幫助或幫助我糾正代碼中的任何錯誤！

Answer 1

您應該通過以下方式從CloudCode返回數據：

response.success(httpResponse.text);

並像這樣在JavaScript中使用數據

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

您現在將看到結果。
