我有SWF對象的實現來修改IE的跨域請求的XHR對象。基於SWF的xhr和amplifyJS - 狀態200但錯誤函數得到執行
一旦對象可我修改療法XHR這樣的：
if ($.browser.msie) {
amplify.subscribe("request.before.ajax", function (resource, settings, ajaxSettings, xhr) {
if (resource.url.indexOf(requestConfig.apiUrl) != -1) {
xhr.setRequestHeader("Accept", "application/xml, text/xml");
var shr = new SWFHttpRequest();
ajaxSettings.xhr = function() {
return shr;
};
ajaxSettings.crossDomain = false;
ajaxSettings.error = function (e) {
// Returns the data object I expect:
alert(e.responseText);
}
}
});
};
我的jQuery ajaxError拋出的錯誤是：語法錯誤：無效字符
- 錯誤是由一個反斜槓引起的：
當我在我的JSON中，例如："Username" : "DOM\\PRO4"它以某種方式變成"DOM\PRO4"給瀏覽器，並給予Syn稅收錯誤。但服務器正在逃跑，因爲我可以看到從服務器發送的原始數據具有\但由於某種原因，我可以理解Flash可能會破壞這一點。
響應從IE身體是：
{
"ResponseCode": 200,
"ResponseDescription": "OK",
"ResponseEntity": [
{
"Id": "6d0d9471-f118-4984-9182-a20300a037b6",
"Name": "DYN",
"ConnectionTypeId": "20000000-0000-0000-0003-000000000003",
"ConnectionTypeName": null,
"Address": "http://54.229.51.444:7777/CRMServer",
"UserName": "DOM\\PRO4",
"Password": "",
"AddedById": "20000000-0000-0000-0004-000000000001",
"DateAdded": "07/22/2013 09:43:20",
"DateModified": "22/07/2013 15:00:01",
"ModifiedById": "",
"TypeName": "Dynamics"
}
]
}
，你可以看到用戶名是正確轉義，但THR AJAX設置錯誤警報顯示了responseText的用戶名只有1反斜槓。
，如果你還需要看看SWF對象，其改進的一個開源模塊的版本使用haXe的開發：
