我在浏览器中从js调用了我的Parse Cloud函数。我只是在做一个测试。我正在尝试拨打http://api.geonames.org
进行GET调用。如果我在浏览器中以http://api.geonames.org/citiesJSON?north=44.1&south=-9.9&east=-22.4&west=55.2&lang=de&username=demo
执行它,它确实有效。它返回:解析云端httpRequest未返回响应

而如果我在云代码执行它:我在本地的机器
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);
},
});
});
随着脚本:
<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个状态,但没有数据。我确信我部署了我的代码,并且我在Parse.com的Cloud Code选项卡中看到了最新的代码,因此我确实不会在云上运行旧代码。
您是否知道如何从Cloud Code中正确进行GET调用? 关于这个主题的任何帮助或帮助我纠正我的代码中的任何错误,非常感谢!
如果它正是你正在运行的代码,CloudCode函数返回一个字符串'response.success >>>>'成功,对不对?但是你的JavaScript代码试图从字符串中获得'httpRequest'。 – iForests
你是什么意思?对不起,我听不懂......你是说我不应该从response.success返回'成功>>>>'? – idelara
是的。我认为你应该'response.success(httpResponse.text);'和'alert(result);'。浏览器会通知Json'{“geonames”:[{“fcodeName”:“ca ...'now。 – iForests
