我使用jQuery来调用.Net web服务，像这样：
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,textStatus,errorThrown) { ajaxError(XMLHttpRequest,errorThrown); },success: function(xml) { DoSomething(xml); }
});
现在我想在Windows身份验证中包装“https://example.com/myservice.asmx”。如何使用jQuery / javascript将凭据传递到服务？
解决方法
看来您需要手动设置base64授权数据的请求头。
说明在这里：http://coderseye.com/2007/how-to-do-http-basic-auth-in-ajax.html
你首先需要从这里取下面的代码：http://www.webtoolkit.info/javascript-base64.html做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,chr3;
var enc1,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;
}
}
然后你需要的代码来构造auth数据，它只是一个base64的用户和密码：
function make_base_auth(user,password) {
var tok = user + ':' + password;
var hash = Base64.encode(tok);
return "Basic " + hash;
}
var service_url = "https://example.com/myservice.asmx"
$.ajax({
type: "GET",beforeSend : function(req) {
req.setRequestHeader('Authorization',make_base_auth ('USERNAME','PASSWORD'));
},errorThrown) {
ajaxError(XMLHttpRequest,errorThrown);
},success: function(xml) { DoSomething(xml); }
});
