ios WKWebView Cookie

WKWebView Cookie 加载cookie有两种方式
1、使用js注入的形式添加
2、使用请求头的形式添加

一使用js注入

        //设置网页的配置文件
        WKWebViewConfiguration * Configuration = [[WKWebViewConfiguration alloc]init];
        //允许视频播放
        Configuration.allowsAirPlayForMediaPlayback = YES;
        // 允许在线播放
        Configuration.allowsInlineMediaPlayback = YES;
        // 允许可以与网页交互，选择视图
        Configuration.selectionGranularity = YES;
        // web内容处理池
        Configuration.processPool = [[WKProcessPool alloc] init];
        
        //自定义配置,一般用于 js调用oc方法(OC拦截URL中的数据做自定义操作)
        WKUserContentController * UserContentController = [[WKUserContentController alloc]init];
        // 添加消息处理，注意：self指代的对象需要遵守WKScriptMessageHandler协议，结束时需要移除
        [UserContentController addScriptMessageHandler:self name:H1WebJS];
        // 将所有cookie以document.cookie = 'key=value';形式进行拼接 
        // key=value key也就是你们后台定的接受参数。value就是常用的cookie的值，切记cookie的值是需要特殊编码(/ = 等)
        NSString *cookieValue = [NSString stringWithFormat:@"document.cookie='userid=%@';", [PBUtility stringSpecialEncode:[UserObject shareUser].cookie]];
        WKUserScript * cookieScript = [[WKUserScript alloc] initWithSource: cookieValue injectionTime:WKUserScriptInjectionTimeAtDocumentStart forMainFrameOnly:NO];
        [UserContentController addUserScript:cookieScript];
        
        // 是否支持记忆读取
        Configuration.suppressesIncrementalRendering = YES;
        // 允许用户更改网页的设置
        Configuration.userContentController = UserContentController;
        
        _wkWebView = [[WKWebView alloc] initWithFrame:self.view.bounds configuration:Configuration];

使用js注入形式有个问题，请求第一个网页的时候，抓包发现没有看到userid=cookie的值，点击二级网页的时候携带了userid=cookie的值

二使用请求头形式

- (void)addCookieKey:(NSString *)cookiekey cookieValue:(NSString *)cookieValue cookieOriginURL:(NSString *)urlString
{
    // 记得单独的cookievalue要特殊编码 = / 编码(也就是特殊字符)
    NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary];
    [cookieProperties setObject:cookiekey forKey:NSHTTPCookieName];
    [cookieProperties setObject:[PBUtility stringSpecialEncode:cookieValue] forKey:NSHTTPCookieValue];
    // cookie对应的url 没有的话NSHTTPCookie生成为nil 这里可以根据项目需求自己定义
    [cookieProperties setObject:@"http://gr-share.com" forKey:NSHTTPCookieOriginURL];
    // 设置cookie的范围路径
    [cookieProperties setObject:@"/" forKey:NSHTTPCookiePath];
    [cookieProperties setObject:@"0" forKey:NSHTTPCookieVersion];
    
    // 将可变字典转化为cookie
    NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:cookieProperties];
    [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
}
- (void)loadRequestWithUrlString:(NSString *)urlString
{
    //缓存web清除
    [[NSURLCache sharedURLCache] removeAllCachedResponses];
    // 保存需要的cookie
    [self addCookieKey:@"userid" cookieValue:[UserObject shareUser].cookie cookieOriginURL:self.URLString];
    
    // 在此处获取返回的cookie
    NSMutableDictionary *cookieDic = [NSMutableDictionary dictionary];
    NSMutableString *cookieValue = [NSMutableString string];
    
    NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage];
    for (NSHTTPCookie *cookie in [cookieJar cookies]) {
        [cookieDic setObject:cookie.value forKey:cookie.name];
    }
    // cookie重复，先放到字典进行去重，再进行拼接
    for (NSString *key in cookieDic) {
        NSString *appendString = [NSString stringWithFormat:@"%@=%@;", key, [cookieDic valueForKey:key]];
        [cookieValue appendString:appendString];
    }
// 抓包其他web项目的写法cookie的最后一个不应该带有;
    NSString *cookies = [cookieValue substringWithRange:NSMakeRange(0, cookieValue.length - 1)];
//    cookies = [NSString stringWithFormat:@"userid=%@", [UserObject shareUser].cookie];
    
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlString] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:15];
    [request addValue:cookies forHTTPHeaderField:@"Cookie"];
    
    //加载网页
    [self.wkWebView loadRequest:request];
}

抓包发现，userid=xxx会在第一个请求的url的header里面会携带，进入二级页面没有看到userid=xxx。这个就需要看下问题了

可以好好测试了
