如何使用jQuery将windows身份验证传递给webservice?
我使用jQuery调用.Net web服务,如下所示:如何使用jQuery将windows身份验证传递给webservice?,jquery,web-services,windows-authentication,Jquery,Web Services,Windows Authentication,我使用jQuery调用.Net web服务,如下所示: var service_url = "https://example.com/myservice.asmx" $.ajax({ type: "GET", url: service_url, dataType: "xml", data: "ParamId=" + FormId.value, processData: false, error: function(XMLHttpRequest, t

processData: false,
error: function(XMLHttpRequest, textStatus, errorThrown) { ajaxError(XMLHttpRequest, textStatus, errorThrown); },
success: function(xml) { DoSomething(xml); }
});
现在我想在Windows身份验证中包装“”。如何使用jQuery/javascript向服务传递凭据
理想情况下,我希望使用当前用户的凭据,但如果需要,我可以为所有服务调用使用1个主凭据 似乎需要手动使用base64身份验证数据设置请求头 说明如下: 首先需要从这里获取以下代码:执行base64编码
/**
*
* Base64 encode / decode
* http://www.webtoolkit.info/
*
**/
var Base64 = {
// private property
_keyStr : "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=",
// public method for encoding
encode : function (input) {
var output = "";
var chr1, chr2, chr3, enc1, enc2, enc3, enc4;
var i = 0;
input = Base64._utf8_encode(input);
while (i < input.length) {
chr1 = input.charCodeAt(i++);
chr2 = input.charCodeAt(i++);
chr3 = input.charCodeAt(i++);
enc1 = chr1 >> 2;
enc2 = ((chr1 & 3) << 4) | (chr2 >> 4);
enc3 = ((chr2 & 15) << 2) | (chr3 >> 6);
enc4 = chr3 & 63;
if (isNaN(chr2)) {
enc3 = enc4 = 64;
} else if (isNaN(chr3)) {
enc4 = 64;
}
output = output +
this._keyStr.charAt(enc1) + this._keyStr.charAt(enc2) +
this._keyStr.charAt(enc3) + this._keyStr.charAt(enc4);
}
return output;
},
// public method for decoding
decode : function (input) {
var output = "";
var chr1, chr2, chr3;
var enc1, enc2, enc3, enc4;
var i = 0;
input = input.replace(/[^A-Za-z0-9\+\/\=]/g, "");
while (i < input.length) {
enc1 = this._keyStr.indexOf(input.charAt(i++));
enc2 = this._keyStr.indexOf(input.charAt(i++));
enc3 = this._keyStr.indexOf(input.charAt(i++));
enc4 = this._keyStr.indexOf(input.charAt(i++));
chr1 = (enc1 << 2) | (enc2 >> 4);
chr2 = ((enc2 & 15) << 4) | (enc3 >> 2);
chr3 = ((enc3 & 3) << 6) | enc4;
output = output + String.fromCharCode(chr1);
if (enc3 != 64) {
output = output + String.fromCharCode(chr2);
}
if (enc4 != 64) {
output = output + String.fromCharCode(chr3);
}
}
output = Base64._utf8_decode(output);
return output;
},
// private method for UTF-8 encoding
_utf8_encode : function (string) {
string = string.replace(/\r\n/g,"\n");
var utftext = "";
for (var n = 0; n < string.length; n++) {
var c = string.charCodeAt(n);
if (c < 128) {
utftext += String.fromCharCode(c);
}
else if((c > 127) && (c < 2048)) {
utftext += String.fromCharCode((c >> 6) | 192);
utftext += String.fromCharCode((c & 63) | 128);
}
else {
utftext += String.fromCharCode((c >> 12) | 224);
utftext += String.fromCharCode(((c >> 6) & 63) | 128);
utftext += String.fromCharCode((c & 63) | 128);
}
}
return utftext;
},
// private method for UTF-8 decoding
_utf8_decode : function (utftext) {
var string = "";
var i = 0;
var c = c1 = c2 = 0;
while ( i < utftext.length ) {
c = utftext.charCodeAt(i);
if (c < 128) {
string += String.fromCharCode(c);
i++;
}
else if((c > 191) && (c < 224)) {
c2 = utftext.charCodeAt(i+1);
string += String.fromCharCode(((c & 31) << 6) | (c2 & 63));
i += 2;
}
else {
c2 = utftext.charCodeAt(i+1);
c3 = utftext.charCodeAt(i+2);
string += String.fromCharCode(((c & 15) << 12) | ((c2 & 63) << 6) | (c3 & 63));
i += 3;
}
}
return string;
}
}
然后,在发出请求之前,只需使用jQuery添加标题:
var service_url = "https://example.com/myservice.asmx"
$.ajax({
type: "GET",
url: service_url,
dataType: "xml",
data: "ParamId=" + FormId.value,
processData: false,
beforeSend : function(req) {
req.setRequestHeader('Authorization',
make_base_auth ('USERNAME', 'PASSWORD'));
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
ajaxError(XMLHttpRequest, textStatus, errorThrown);
},
success: function(xml) { DoSomething(xml); }
});
我认为现在您可以将请求对象的
withCredentials
属性设置为true
,例如:
$.ajax({
type: "GET",
url: service_url,
dataType: "xml",
data: "ParamId=" + FormId.value,
processData: false,
xhrFields: {
withCredentials: true
},
error: function(XMLHttpRequest, textStatus, errorThrown) { ajaxError(XMLHttpRequest, textStatus, errorThrown); },
success: function(xml) { DoSomething(xml); }
});
这会导致在AJAX请求中传递现有的身份验证头/cookie,这对我很有用。不需要自己进行基本编码等。这是基本身份验证。这对我不起作用,要使用windows Authentication进行身份验证,如果我使用base64 encrypt加密userid&pwd,那么我想我需要在服务端编写extrac代码来解密数据?“我说得对吗?”托马斯:这对我也不管用。你找到解决方案了吗?你没有说IE的版本是什么,但这只是使用jquery API,所以理论上它应该适用于jquery支持的每一个IE版本。试试看!我如何发送json?你在哪里传递用户名和密码?如果有人需要显式地传递userid和password,那么withCredentials如何提供帮助?@Thomas这个问题询问Windows身份验证,这是隐式传递的调用方的凭据。不明确。所以问题是如何不显式地传递凭据。@ADyson,我已经在Chrome、Firefox和IE上试过了。它们都不能在跨域请求中发送凭据。
$.ajax({
type: "GET",
url: service_url,
dataType: "xml",
data: "ParamId=" + FormId.value,
processData: false,
xhrFields: {
withCredentials: true
},
error: function(XMLHttpRequest, textStatus, errorThrown) { ajaxError(XMLHttpRequest, textStatus, errorThrown); },
success: function(xml) { DoSomething(xml); }
});
