[iOS]实现UIWebView的自动登陆

IOS中UIWebView不会自动存储、读取Cookie.

要实现UIWebView的自动登陆,需要手动存储、读取Cookie.

1.Appelegate.m中加入以下代码

- (void)applicationDidBecomeActive:(UIApplication *)application

{

[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways];

}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

//存储Cookie,示例加载的URL:http://119.29.69.58:81/index

NSURL * cookieHost = [NSURL URLWithString:@"http://119.29.69.58:81"];

NSHTTPCookie * cookie = [NSHTTPCookie cookieWithProperties:

[NSDictionary    dictionaryWithObjectsAndKeys:

[cookieHost host],NSHTTPCookieDomain,

[cookieHost path],NSHTTPCookiePath,

@"COOKIE_NAME",NSHTTPCookieName,

@"COOKIE_VALUE",NSHTTPCookieValue,nil]];

[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];

}

2.UIWebView加载URL时设置Header

NSURL * url = [NSURL URLWithString:@"http://119.29.69.58:81/index"];

NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:url];

NSArray * cookies = [[NSHTTPCookieStorage  sharedHTTPCookieStorage] cookies];

NSDictionary * headers = [NSHTTPCookie requestHeaderFieldsWithCookies:cookies];

[request setHTTPMethod:@"POST"];

[request setHTTPShouldHandleCookies:YES];

[request setAllHTTPHeaderFields:headers];

[self.WebView loadRequest:request];

3.退出登陆时删除Cookie

//清空Cookie

NSHTTPCookieStorage * myCookie = [NSHTTPCookieStorage sharedHTTPCookieStorage];

for (NSHTTPCookie * cookie in [myCookie cookies])

{

[[NSHTTPCookieStorage sharedHTTPCookieStorage] deleteCookie:cookie];

}

//删除沙盒自动生成的Cookies.binarycookies文件

NSString * path = NSHomeDirectory();

NSString * filePath = [path stringByAppendingPathComponent:@"/Library/Cookies/Cookies.binarycookies"];

NSFileManager * manager = [NSFileManager defaultManager];

[manager removeItemAtPath:filePath error:nil];
