我有一个使用 JSON 的 WCF REST 样式服务，它在 IE 中运行良好，但 FireFox 和 Chrome 正在发脾气；关于跨域调用的一些东西。
我在这里遵循了建议： 将 JSON 数据从 JQuery 发送到 WCF REST 方法时出现问题
但是我现在看到的是，虽然我的浏览器发送了 2 个请求（首先是 OPTIONS，然后是 POST），但 POST 请求根本没有返回任何内容。再次，IE 与此完美配合。少了什么东西？
JAVASCRIPT：
<script type="text/javascript">
function Search() {
var json = JSON.stringify($('#testForm').serializeObject());
$.ajax(
{
type: "POST",
url: "http://localhost:8000/MyService.svc/Search",
data: json,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response, status, xhr) {
GetResults(response.SearchResult.QueryId);
},
error: function (xhr, status, error) {
alert("Error\n-----\n" + xhr.status + '\n' + xhr.responseText);
},
//complete: function (jqXHR, status) { alert('Status: ' + status + '\njqXHR: ' + JSON.stringify(jqXHR)); }
});
return false;
}
function GetResults(queryId) {
debugger;
$.ajax(
{
type: "GET",
url: "http://localhost:8000/MyService.svc/GetResults?queryId=" + queryId + "&ignoreXmlFeedSourceIds=",
//data: {},
contentType: 'application/json; charset=utf-8',
dataType: "json",
success: function (response, status, xhr) {
debugger;
DoSomethingWithResults(response);
},
error: function (xhr, status, error) {
alert(error);
},
complete: function (jqXHR, status) { alert('Status: ' + status + '\njqXHR: ' + JSON.stringify(jqXHR)); }
});
}
function DoSomethingWithResults(results) {
alert("In DoSomethingWithResults()");
// process the results here to show on UI
debugger;
};
$.fn.serializeObject = function () {
var o = {};
var a = this.serializeArray();
$.each(a, function () {
if (o[this.name] !== undefined) {
if (!o[this.name].push) {
o[this.name] = [o[this.name]];
}
o[this.name].push(this.value || '');
} else {
o[this.name] = this.value || '';
}
});
return o;
};
</script>
