根据ID拿到输入密码的输入框并给值

自动点击登录按钮

@"document.getElementById('login').click()"
根据ID获取登录按钮这个元素,并调用其点击事件click()

如果有特别限制的话,我们需要先访问一次特定网址,并存入cookie

NSURL * cookieHost = [NSURL URLWithString:@"http://mmmmmm/login/Login.jsp"];
NSHTTPCookie * cookie = [NSHTTPCookie cookieWithProperties:
[NSDictionary dictionaryWithObjectsAndKeys:
[cookieHost host],NSHTTPCookieDomain,
[cookieHost path],NSHTTPCookiePath,
@"COOKIE_NAME",NSHTTPCookieName,
@"COOKIE_VALUE",NSHTTPCookieValue,nil]];
[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];

退出登录里为了,不受其他干扰,要清掉cookie

NSHTTPCookieStorage * myCookie = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (NSHTTPCookie * cookie in [myCookie cookies])
{
[[NSHTTPCookieStorage sharedHTTPCookieStorage] deleteCookie:cookie];
} NSString * path = NSHomeDirectory();
NSString * filePath = [path stringByAppendingPathComponent:@"/Library/Cookies/Cookies.binarycookies"];
NSFileManager * manager = [NSFileManager defaultManager];
[manager removeItemAtPath:filePath error:nil];

开始发起请求,附带上cookie去请求,伪装成特定User-Agent,referer等

NSURL * url = [NSURL URLWithString:@"http://mmmmm/login/Login.jsp"];
NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:url];
NSArray * cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];
NSDictionary * headers = [NSHTTPCookie requestHeaderFieldsWithCookies:cookies];
[request setValue:@"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.98 Safari/537.36" forHTTPHeaderField:@"User-Agent"];
[request setValue:@"http://mmmmmm" forHTTPHeaderField:@"Origin"];
[request setValue:@"http://mmmmm/login/Login.jsp" forHTTPHeaderField:@"Referer"];
[request setHTTPMethod:@"GET"];
[request setHTTPShouldHandleCookies:YES];
[request setAllHTTPHeaderFields:headers];

如果要求在特定的网络环境下才能访问网址,就得处理判断了,当然这种情况下,只能受限了

NSString *ipString = [self deviceIPAdress][@"en1/ipv4"];
ipString = ipString ? ipString : [ self deviceIPAdress][@"en0/ipv4"]; if ([self canLoadNetFrom:ipString]) {
[self.webView loadRequest:request];
} else {
[SVProgressHUD showErrorWithStatus:@"当前网络环境不支持登录"];
}

更新:要切换不同账户密码怎么办,重新写程序?这里用Settings.bundle

OC JS交互(通常情况下,如果网页写得正规的话,是可以正常交互的,之前就遇到后台写h5始终拿不到事件,元素也拿不到,更别说交互了,真是奇了怪了)

然后直接用偏好去取就是了

NSUserDefaults *user = [NSUserDefaults standardUserDefaults];
NSString *accout = [user stringForKey:@"name_preference"];
NSString *psd = [user stringForKey:@"psd_preference"];
