我正在與SkyScanner API合作以獲取按航班詳細信息顯示的實時價格。如何在get方法中使用post方法中的getResponseHeader?
正如文檔所述。我創建了實時定價服務會議。可以通過向api發送請求來創建,然後通過使用這個SessionKey和apiKey來提供SessionKey,我可以回顧這些數據。我可以在成功方法中看到使用getResponseHeader(「Location」)的sessionKey。我將它提交給一個全局變量urlSession,我稍後在另一個http獲取請求中使用它作爲url。 我可以在警報中看到SessionKey,但我嘗試在get方法中使用它時出現未定義的錯誤。我不確定它是CORS問題,還是語法。
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);
};
感謝您的回答。我能夠通過hrpost.getResponseHeader('Location')獲取sessionKey,而不用追加apiKey。我的代碼的問題是我正在做的調用順序,我將發佈的http請求設置爲false異步。我在post請求的onload方法中發出了我的get請求。我能夠解決這個架構的問題。 –
