无聊想调用下嘀咕的api的时候，发现需要HTTP Basic Authentication，就看了下。
什么是HTTP Basic Authentication？直接看http://en.wikipedia.org/wiki/Basic_authentication_scheme 吧。
在你访问一个需要HTTP Basic Authentication的URL的时候，如果你没有提供用户名和密码，服务器就会返回401，如果你直接在浏览器中打开，浏览器会提示你输入用户名 和密码(google浏览器不会，bug？)。你可以尝试点击这个url看看效果：http://api.minicloud.com.cn/statuses/friends_timeline.xml
要在发送请求的时候添加HTTP Basic Authentication认证信息到请求中，有两种方法：
下面来看下对于第一种在请求中添加Authorization头部的各种语言的实现代码。
先看.NET的吧：
-
string username="username";
-
string password="password";
-
-
string usernamePassword = username + ":" + password;
-
CredentialCache mycache = new CredentialCache();
-
mycache.Add(new Uri(url), "Basic", new NetworkCredential(username, password));
-
myReq.Credentials = mycache;
-
myReq.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(new ASCIIEncoding().GetBytes(usernamePassword)));
-
-
WebResponse wr = myReq.GetResponse();
-
Stream receiveStream = wr.GetResponseStream();
-
StreamReader reader = new StreamReader(receiveStream, Encoding.UTF8);
-
string content = reader.ReadToEnd();
你当然也可以使用HttpWebRequest或者其他的类来发送请求。
然后是Python的：
-
import urllib2
-
import sys
-
import re
-
import base64
-
from urlparse import urlparse
-
-
theurl = 'http://api.minicloud.com.cn/statuses/friends_timeline.xml'
-
-
username = 'qleelulu'
-
password = 'XXXXXX' # 你信这是密码吗？
-
-
base64string = base64.encodestring(
-
'%s:%s' % (username, password))[:-1] #注意哦，这里最后会自动添加一个n
-
authheader = "Basic %s" % base64string
-
req.add_header("Authorization", authheader)
-
try:
-
handle = urllib2.urlopen(req)
-
except IOError, e:
-
# here we shouldn't fail if the username/password is right
-
print "It looks like the username or password is wrong."
-
sys.exit(1)
-
thepage = handle.read()
再来是PHP的：
-
<?php
-
$fp = fsockopen("www.mydomain.com",80);
-
fputs($fp,"GET /downloads HTTP/1.0");
-
fputs($fp,"Host: www.mydomain.com");
-
fputs($fp,"Authorization: Basic " . base64_encode("user:pass") . "");
-
fpassthru($fp);
-
?>
还有flash的AS3的：
-
import mx.rpc.events.FaultEvent;
-
import mx.rpc.events.ResultEvent;
-
import mx.utils.Base64Encoder;
-
import mx.rpc.http.HTTPService;
-
URLRequestDefaults.authenticate = false;
-
-
private var result:XML;
-
private function initApp():void
-
{
-
var base64enc:Base64Encoder = new Base64Encoder;
-
base64enc.encode("user:password");
-
var user:String = base64enc.toString();
-
-
var http:HTTPService = new HTTPService;
-
http.addEventListener(ResultEvent.RESULT,resultHandler);
-
http.addEventListener(FaultEvent.FAULT,faultHandler);
-
http.resultFormat = "e4x";
-
http.url = "http://api.digu.com/statuses/friends_timeline.xml"; 以嘀咕网的API为列
-
http.headers = {"Authorization":"Basic " + user};
-
http.send();
-
}
-
private function resultHandler(e:ResultEvent):void
-
{
-
result = XML(e.result);
-
test.dataProvider = result.status;
-
}
-
private function faultHandler(e:ResultEvent):void
-
{
-
-
}
还有Ruby On Rails的：
-
class DocumentsController < ActionController
-
before_filter :verify_access
-
-
def show
-
@document = @user.documents.find(params[:id])
-
end
-
-
# Use basic authentication in my realm to get a user object.
-
# Since this is a security filter - return false if the user is not
-
# authenticated.
-
def verify_access
-
authenticate_or_request_with_http_basic("Documents Realm") do |username, password|
-
@user = User.authenticate(username, password)
-
end
-
end
-
end
JavaScript的：
-
-
function make_base_auth(user, password) {
-
var tok = user + ':' + pass;
-
var hash = Base64.encode(tok);
-
return "Basic " + hash;
-
}
-
-
var auth = make_basic_auth('QLeelulu','mypassword');
-
var url = 'http://example.com';
-
-
-
xml = new XMLHttpRequest();
-
xml.setRequestHeader('Authorization', auth);
-
xml.open('GET',url)
-
-
-
Ext.Ajax.request({
-
url : url,
-
method : 'GET',
-
headers : { Authorization : auth }
-
});
-
-
-
$.ajax({
-
url : url,
-
method : 'GET',
-
beforeSend : function(req) {
-
req.setRequestHeader('Authorization', auth);
-
}
-
});
这里提醒下，HTTP Basic Authentication对于跨域又要发送post请求的用JavaScript是实现不了的(注：对于Chrome插件这类允许通过AJAX访问跨域资源的，是可以的)。
