iOS WKWebView添加cookie

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：

#pragma mark - 拼接cookie
- (NSString*)readCurrentCookieWith:(NSDictionary*)dic{
    if (dic == nil) {
        return nil;
    }else{
        NSHTTPCookieStorage*cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage];
        NSMutableString *cookieString = [[NSMutableString alloc] init];
        for (NSHTTPCookie*cookie in [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]; [cookieProperties setObject:@"cookie_user" forKey:NSHTTPCookieName]; [cookieProperties setObject:uid forKey:NSHTTPCookieValue]; [cookieProperties setObject:@"xxx.xxx.com" forKey:NSHTTPCookieDomain]; [cookieProperties setObject:@"/" forKey:NSHTTPCookiePath]; [cookieProperties setObject:@"0" forKey:NSHTTPCookieVersion]; [cookieProperties setObject:[[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 (cookie in cookieAry) { [cookieJar deleteCookie: cookie]; } }
