ios url 要求標頭添加參數及自訂cookie

   通過要求標頭可以傳遞 一些web 想要的一些資訊，但是這個方法有些局限性，如果web 跳轉的時候頭的資訊會訊息，最好的方法就是自訂cookie 傳值

   NSURL* url = [NSURL URLWithString:self.url];

  NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL: url];

   NSString *body = [NSString stringWithFormat: @"uuid=%@&sessionid=%@", uuid,sessionid];

   [request setHTTPBody: [body dataUsingEncoding: NSUTF8StringEncoding]];

   [request setHTTPMethod: @"POST"];

    [self.myWebView loadRequest:request];

    [self.view addSubview:self.myWebView];

  

  自訂ccokie 傳值

  // 定義 cookie 要設定的 host

   NSURL* url = [NSURL URLWithString:self.url];

    NSURL *cookieHost = [NSURL URLWithString:self.url];

    NSDictionary *dic = @{@"uuid":uuid,@"sessionid":sessionid,@"feedid":self.feedid,@"softversion":softversion,@"devicetype":deviceId,@"touuid":   self.touuid};

    [dic enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {

     // 設定 cookie

    NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:

                                [NSDictionary dictionaryWithObjectsAndKeys:

                                 [cookieHost host], NSHTTPCookieDomain,

                                 [cookieHost path], NSHTTPCookiePath,

                                 key,NSHTTPCookieName,

                                 obj,NSHTTPCookieValue,

                                 nil]];

    [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];

        

    }];

    [self.myWebView loadRequest:request];//載入

    [self.view addSubview:self.myWebView];
