一篇文章搞定iOS的Cookie存取

// 工厂类中存储cookie的方法
+ (void)saveCookies {
 // 创建一个可变字典存放cookie
 NSMutableDictionary *fromappDict = [NSMutableDictionary dictionary];
 [fromappDict setObject:@"fromapp" forKey:NSHTTPCookieName];
 [fromappDict setObject:@"ios" forKey:NSHTTPCookieValue];
 // kDomain是公司app网址
 [fromappDict setObject:kDomain forKey:NSHTTPCookieDomain];
 [fromappDict setObject:kDomain forKey:NSHTTPCookieOriginURL];
 [fromappDict setObject:@"/" forKey:NSHTTPCookiePath];
 [fromappDict setObject:@"0" forKey:NSHTTPCookieVersion];
 // 将可变字典转化为cookie
 NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:fromappDict];
 // 获取cookieStorage
 NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage]
 // 存储cookie
 [cookieStorage setCookie:cookie];
}

 WKWebViewConfiguration *webConfig = [[WKWebViewConfiguration alloc] init];
 // 设置偏好设置
 webConfig.preferences = [[WKPreferences alloc] init];
 // 默认为0
 webConfig.preferences.minimumFontSize = 10;
 // 默认认为YES
 webConfig.preferences.javaScriptEnabled = YES;
 // 在iOS上默认为NO，表示不能自动通过窗口打开 webConfig.preferences.javaScriptCanOpenWindowsAutomatically = NO;
 // web内容处理池
 webConfig.processPool = [[WKProcessPool alloc] init];
 // 将所有cookie以document.cookie = 'key=value';形式进行拼接
 #warning 然而这里的单引号一定要注意是英文的，不要问我为什么告诉你这个(手动微笑)
 NSString *cookieValue = @"document.cookie = 'fromapp=ios';document.cookie = 'channel=appstore';"; 
 // 加cookie给h5识别，表明在ios端打开该地址
 WKUserContentController* userContentController = WKUserContentController.new;
 WKUserScript * cookieScript = [[WKUserScript alloc]
         initWithSource: cookieValue         injectionTime:WKUserScriptInjectionTimeAtDocumentStart forMainFrameOnly:NO];
 [userContentController addUserScript:cookieScript];
 webConfig.userContentController = userContentController;
 WKWebView *wkWebView = [[WKWebView alloc] initWithFrame:frame configuration:webConfig];
 wkWebView.UIDelegate = wkWebView;
 wkWebView.navigationDelegate = wkWebView;

- (void)loadRequestWithUrlString:(NSString *)urlString { 
 // 在此处获取返回的cookie
 NSMutableDictionary *cookieDic = [NSMutableDictionary dictionary]; 
 NSMutableString *cookieValue = [NSMutableString stringWithFormat:@""];
 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];
 }
 NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlString]];
 [request addValue:cookieValue forHTTPHeaderField:@"Cookie"];
 [self loadRequest:request];
}

AFNetworking存取cookie就比较常见了，话不多说，都在代码里了
 // 获取AFHTTPRequestOperationManager
 AFHTTPRequestOperationManager *operationManager = [AFHTTPRequestOperationManager manager]; 
 // 创建可变字典用于存放Cookie
 NSMutableDictionary *cookieDic = [NSMutableDictionary dictionary]; 
 // 存放新添加的cookie
 #warning 单个的Cookie还好，但是楼主在工厂类方法中拼接了一个包含6个设备信息的value值，最后忘记加分号了，测试也没测出来
 #warning 因为不影响功能，但是后面的cookie就自动拼接上了，H5那边也识别不到，险造成重大事故(涉及金融。。)，望后来者看到，提前做好准备(就凭这个坑，你得给我个赞)
 NSMutableString *cookieValue = [NSMutableString stringWithFormat:@"fromapp=ios;"];
 // 获取
 NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage]; 
 for (NSHTTPCookie *cookie in [cookieJar cookies]) {
  [cookieDic setObject:cookie.value forKey:cookie.name];
 } 
 // cookie重复，先放到字典去重，再进行拼接
 for (NSString *key in cookieDic) {
  NSString *appendString = [NSString stringWithFormat:@"%@=%@;", key, [cookieDic valueForKey:key]];
  [cookieValue appendString:appendString];
 }
 // 将cookie存到请求头中
 [operationManager.requestSerializer setValue:cookieValue forHTTPHeaderField:@"Cookie"]; 
 // 拼接url地址
 NSString *urlStr = [NSString stringWithFormat:@"%@%@", kHostIP, kPath]; 
 // 设置参数字典
 NSDictionary *paraDict = @{
         @"key" : value
         };
 // 发送请求，处理结果
 [operationManager POST:urlStr parameters:paraDict success:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) {  
   NSLog(@"responseObject-->%@", responseObject);  
 } failure:^(AFHTTPRequestOperation * _Nullable operation, NSError * _Nonnull error) {

   NSLog(@"error-->%@", error);
 }];
