我正在与SkyScanner API合作以获取按航班详细信息显示的实时价格。如何在get方法中使用post方法中的getResponseHeader?
正如文档所述。我创建了实时定价服务会议。可以通过向api发送请求来创建,然后通过使用这个SessionKey和apiKey来提供SessionKey,我可以回顾这些数据。我可以在成功方法中看到使用getResponseHeader(“Location”)的sessionKey。我将它提交给一个全局变量urlSession,我稍后在另一个http获取请求中使用它作为url。 我可以在警报中看到SessionKey,但我尝试在get方法中使用它时出现未定义的错误。我不确定它是CORS问题,还是语法。
var hrpost = Ti.Network.createHTTPClient();
// post_params
var post_params = {
"apiKey" : {apiKey},
"Country" : "US",
"Currency" : "USD",
"Locale" : "en-GB",
"Adults" : 1,
"Children" : 0,
"Infants" : 0,
"OriginPlace" : "16216",
"DestinationPlace" : "1111",
"OutboundDate" : "2016-09-23",
"InboundDate" : "2016-09-30",
"LocationSchema" : "Default",
"CabinClass" : "Economy",
"GroupPricing" : true
};
var strMyObj = JSON.stringify(post_params);
//Here I set the webservice address and method
hrpost.open('POST', "http://partners.api.skyscanner.net/apiservices/pricing/v1.0");
//Set the headers
hrpost.setRequestHeader("Accept", "application/json");
hrpost.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
hrpost.send(post_params);
hrpost.onload = function(){
alert('Posted successfully');
urlsessionKey = hrpost.getResponseHeader('Location');
alert(urlsessionKey);
}
hrpost.onerror = function() {
alert('request didnt posted');
var rejection = {
status: hrpost.status,
statusText: hrpost.statusText,
};
alert(rejection);
};
//HTTP request get method to send the sessionKey and retrieve data
var xmlHttp = Ti.Network.createHTTPClient();
var post_params = {
"apiKey" : {apiKey},
"Country" : "US",
"Currency" : "USD",
"Locale" : "en-GB",
"Adults" : 1,
"Children" : 0,
"Infants" : 0,
"OriginPlace" : "16216",
"DestinationPlace" : "1111",
"OutboundDate" : "2016-09-23",
"InboundDate" : "2016-09-30",
"LocationSchema" : "Default",
"CabinClass" : "Economy",
"GroupPricing" : true
};
//here the error occurs when I use the sessionKey I stored in the global var urlsessionKey
xmlHttp.open('GET', urlsessionKey);
xmlHttp.setRequestHeader("Accept", "application/json");
xmlHttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
xmlHttp.send(post_params);
xmlHttp.onload = function(e){
alert('Get successfully');
}
xmlHttp.onerror = function() {
alert('request didnt posted');
var rejection = {
status: xmlHttp.status,
statusText: xmlHttp.statusText,
};
alert(rejection);
};
感谢您的回答。我能够通过hrpost.getResponseHeader('Location')获取sessionKey,而不用追加apiKey。我的代码的问题是我正在做的调用顺序,我将发布的http请求设置为false异步。我在post请求的onload方法中发出了我的get请求。我能够解决这个架构的问题。 –
