在网络请求中，有一部分需要添加cookie，接下来就把为web添加cookie的方法小小列举一下，其实所有的要添加cookie的网络请求包括web，最终都是要在request上添加，如下：
if(_webView == nil) {
// 1)创建WebView_webView = [[WKWebView alloc] initWithFrame:CGRectMake(0,0, Kwidth, Kheight-64)];
// 2)设置代理_webView.delegate= self;
_webView.scalesPageToFit = YES;
_webView.scrollView.bounces = NO;
}
// 3)设置URL地址NSURL *url = [NSURL URLWithString:strUrl];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
NSDictionary *cookie = [AppInfo shareAppInfo].userModel.cookies;
if(cookie != nil) {
[request addValue:[self readCurrentCookieWith:cookie] forHTTPHeaderField:@"Cookie"];
}else{
[request addValue:@""forHTTPHeaderField:@"Cookie"];
}
[_webView loadRequest:request];
[self.view addSubview:_webView];
其中获得cookie的信息我封装了一下：
#pragmamark - 拼接cookie- (NSString*)readCurrentCookieWith:(NSDictionary*)dic{
if(dic == nil) {
return nil;
}else{
NSHTTPCookieStorage*cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage];
NSMutableString *cookieString = [[NSMutableString alloc] init];
for(NSHTTPCookie*cookiein [cookieJar cookies]) {
[cookieString appendFormat:@"%@=%@;",cookie.name,cookie.value];
}
//删除最后一个“；”[cookieString deleteCharactersInRange:NSMakeRange(cookieString.length -1,1)];
return cookieString;
}
}
[self setCookie];//设置cookie
在此之前，设置cookie。
//设置cookie
- (void)setCookie{ NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary]; [cookiePropertiessetObject:@"cookie_user"forKey:NSHTTPCookieName]; [cookiePropertiessetObject:uidforKey:NSHTTPCookieValue]; [cookiePropertiessetObject:@"xxx.xxx.com"forKey:NSHTTPCookieDomain];[cookiePropertiessetObject:@"/"forKey:NSHTTPCookiePath]; [cookiePropertiessetObject:@"0"forKey:NSHTTPCookieVersion]; [cookiePropertiessetObject:[[NSDate date] dateByAddingTimeInterval:2629743]forKey:NSHTTPCookieExpires]; NSHTTPCookie *cookieuser = [NSHTTPCookie cookieProperties]; [[NSHTTPCookieStorage sharedHTTPCookieStorage]setCookie:cookieuser];
}
NSHTTPCookieStorage实现管理共享的cookie存储一个singleton对象（共享实例）。 这些cookies是所有的应用程序之间的共享和跨进程同步保存
//清除cookie
- (void)deleteCookie{NSHTTPCookie *cookie;NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage];NSArray *cookieAry = [cookieJar cookiesForURL: [NSURL URLWithString: _urlstr]];for (cookiein cookieAry) {
[cookieJar deleteCookie: cookie];
}
}
