iOS WebView 中的 Cookie场景IP直连的几种方法(2)

猫饭先生 2017-10-20 11:20:02 1235

利用 iOS11 之前的 API 解决 WKWebView 首次请求不携带 Cookie 的问题


通过让所有 WKWebView 共享同一个 WKProcessPool 实例,可以实现多个 WKWebView 之间共享 Cookie(session Cookie and persistent Cookie)数据。不过 WKWebView WKProcessPool 实例在 app 杀进程重启后会被重置,导致 WKProcessPool 中的 Cookie、session Cookie 数据丢失,目前也无法实现 WKProcessPool 实例本地化保存。可以采取 cookie 放入 Header 的方法来做。
  1. [backcolor=transparent] [backcolor=transparent]WKWebView[backcolor=transparent] [backcolor=transparent]*[backcolor=transparent] webView [backcolor=transparent]=[backcolor=transparent] [backcolor=transparent][[backcolor=transparent]WKWebView[backcolor=transparent] [backcolor=transparent]new[backcolor=transparent]];[backcolor=transparent]
  2. [backcolor=transparent] [backcolor=transparent]NSMutableURLRequest[backcolor=transparent] [backcolor=transparent]*[backcolor=transparent] request [backcolor=transparent]=[backcolor=transparent] [backcolor=transparent][[backcolor=transparent]NSMutableURLRequest[backcolor=transparent] requestWithURL[backcolor=transparent]:[[backcolor=transparent]NSURL [backcolor=transparent]URLWithString[backcolor=transparent]:@[backcolor=transparent]"http://xxx.com/login"[backcolor=transparent]]];[backcolor=transparent]
  3. [backcolor=transparent] [backcolor=transparent][[backcolor=transparent]request addValue[backcolor=transparent]:@[backcolor=transparent]"skey=skeyValue"[backcolor=transparent] forHTTPHeaderField[backcolor=transparent]:@[backcolor=transparent]"Cookie"[backcolor=transparent]];[backcolor=transparent]
  4. [backcolor=transparent] [backcolor=transparent][[backcolor=transparent]webView loadRequest[backcolor=transparent]:[backcolor=transparent]request[backcolor=transparent]];

其中对于 skey=skeyValue 这个cookie值的获取,也可以统一通过domain获取,获取的方法,可以参照下面的工具类:
  1. [backcolor=transparent]HTTPDNSCookieManager[backcolor=transparent].[backcolor=transparent]h
  2. [backcolor=transparent]#ifndef[backcolor=transparent] [backcolor=transparent]HTTPDNSCookieManager_h
  3. [backcolor=transparent]#define[backcolor=transparent] [backcolor=transparent]HTTPDNSCookieManager_h
  4. [backcolor=transparent]// URL匹配Cookie规则

  6. [backcolor=transparent]@interface[backcolor=transparent] [backcolor=transparent]HTTPDNSCookieManager[backcolor=transparent] [backcolor=transparent]:[backcolor=transparent] [backcolor=transparent]NSObject
