如何从jQuery Get获取响应头位置？
如何从jQuery Get获取响应头位置？
提问于 2012-06-27 18:17:31
因此，我尝试通过jQuery get从头响应中获取位置。我尝试使用getResponseHeader('Location')和getAllResponseHeaders()，但它们似乎都返回null。
这是我当前的代码
$(document).ready(function(){
var geturl;
geturl = $.ajax({
type: "GET",
url: 'http://searchlight.cluen.com/E5/Login.aspx?URLKey=uzr7ncj8)',
});
var locationResponse = geturl.getResponseHeader('Location');
console.log(locationResponse);
});回答 2

对于jQuery Ajax中的一些标头，您需要访问XMLHttpRequest对象
var xhr;
var _orgAjax = jQuery.ajaxSettings.xhr;
jQuery.ajaxSettings.xhr = function () {
xhr = _orgAjax();
return xhr;
};
$.ajax({
type: "GET",
url: 'http://example.com/redirect',
success: function(data) {
console.log(xhr.responseURL);
}
});或使用普通的javascript
var xhr = new XMLHttpRequest();
xhr.open('GET', "http://example.com/redirect", true);
xhr.onreadystatechange = function () {
if (this.readyState == 4 && this.status == 200) {
console.log(xhr.responseURL);
}
};
xhr.send();Stack Overflow用户

jQuery将XMLHttpRequest对象抽象为一个所谓的“超集”，它不会公开responseURL字段。他们在文档中谈到了"jQuery XMLHttpRequest (jqXHR)对象“。
For backward compatibility with XMLHttpRequest, a jqXHR object will expose the following properties and methods:
readyState
responseXML and/or responseText when the underlying request responded with xml and/or text, respectively
status
statusText
abort( [ statusText ] )
getAllResponseHeaders() as a string
getResponseHeader( name )
overrideMimeType( mimeType )
setRequestHeader( name, value ) which departs from the standard by replacing the old value with the new one rather than concatenating the new value to the old one
statusCode( callbacksByStatusCode )
No onreadystatechange mechanism is provided, however, since done, fail, always, and statusCode cover all conceivable requirements.正如您所看到的，没有办法获得响应URL，因为jqXHR应用编程接口不公开它
