Question

我有两个网站使用相同的JavaScript代码与多个网络服务进行交互。代码在一个站点中完美运行，但在另一个站点中，它以text / xml格式发送数据。我查看了两个站点中的Web配置文件，但无法发现可能导致差异的任何内容。 AjaxControlToolkit DLL文件是相同的。 AJAX调用因错误500而失败，因为数据格式不正确。

进行AJAX调用的代码：

function displaySessionNotifications() {
$.ajax({
type: "POST",
async: false,
url: "NotificationService.asmx/ListSessionNotifications",
contentType: "application/json; charset=utf-8",
dataType: "json",
data: JSON.stringify({}),
success: function (data) {
$list = JSON.parse(data.d);
if (window.console.log) { window.console.log('Notification Service Msg Cnt: ' + $list.length) };
for (var i = 0; i < $list.length; i++) {
displayMessage($list[i].MessageText, $list[i].MessageType, $list[i].IsSticky, $list[i].jGrowlClass, $list[i].ContainerId);
};
if ($list.length > 0) {
clearSessionNotifications($list[0].SessionId);
}
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("NotificationService/ListSessionNotifications failed: " + XMLHttpRequest.responseText);
}
});
}

观看Firebug的数据：

此 Object {url =“NotificationService.asmx / ListSessionNotifications”，global = true，type =“POST”，more ...}

XMLHttpRequest
    Object { readyState=4, status=0, statusText="error"}

errorThrown
    [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE)" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js :: <TOP_LEVEL> :: line 16" data: no] { name="NS_ERROR_FAILURE", message="Component returned fail...4005 (NS_ERROR_FAILURE)", result=2147500037, more...}

textStatus
    "error"
