After some research briefly I understand: when you visit a website, whether you are willing or unwilling, nsurlrequest will help you take the initiative to record the site you visit the cookie set, and very responsible, when you visit this site next time, Nsurlrequest will take the last saved cookie and continue to request it. The same rule applies to Asihttprequest. So when you do some authentication-based network requests, cookies are a perfect solution.</p></p><p><p>So how do you look at cookies? Very simple:</p></p> <table cellspacing="0" cellpadding="0"> <tbody> <tr> <td class="line-numbers">1<br>2<br>3<br>4</td> <td>Nshttpcookiestorage *cookiejar = [nshttpcookiestorage sharedhttpcookiestorage];<br>For (nshttpcookie *cookie in [cookiejar cookies]) {<br>NSLog (@ "%@", cookie);<br>}</td> </tr> </tbody> </table><p><p>This lists all the saved cookies and what if they are currently empty? Ask for a URL at random.</p></p> <table cellspacing="0" cellpadding="0"> <tbody> <tr> <td class="line-numbers">1<br>2<br>3<br>4<br>5<br>6<br>7<br>8<br>9<br>10<br>11<br>12</td> <td>Nsurlrequest *request = [nsurlrequest requestwithurl:[nsurl urlwithstring:@ "http://blog.cnrainbird.com"]<br>Cachepolicy:nsurlrequestreloadignoringlocalandremotecachedata<br>timeoutinterval:3];<br><br>[nsurlconnection Sendsynchronousrequest:request<br>Returningresponse:nil<br>error:nil];<br><br>Nshttpcookiestorage *cookiejar = [nshttpcookiestorage sharedhttpcookiestorage];<br>For (nshttpcookie *cookie in [cookiejar cookies]) {<br>NSLog (@ "%@", cookie);<br>}</td> </tr> </tbody> </table><p><p>is not getting a similar:</p></p> <table cellspacing="0" cellpadding="0"> <tbody> <tr> <td class="line-numbers">1</td> <td><nshttpcookie version:0 name: "phpsessid" value: "evf5rcboo8th1dnl53fs4ukmt2" expiresdate: (null) created : 2012-03-13 14:28:13 +0000 (3.53342e+08) sessiononly:true domain: "blog.cnrainbird.com" path: "/" issecure:false></td> </tr> </tbody> </table><p><p>The stuff?
