iOS 和 H5 页面交互(WKWebview 和 UIWebview cookie 设置)
主要记录关于cookie相关的坑
1. UIWebview
1. UIWebview 相对比较简单 直接通过 NSHTTPCookieStorage 设置cookie就能实现。
代码部分
``` NSURL *cookieHost = [NSURL URLWithString:self.domain]; // 设定 cookie NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties: [NSDictionary dictionaryWithObjectsAndKeys: [cookieHost host], NSHTTPCookieDomain, [cookieHost path], NSHTTPCookiePath, self.cookieKey, NSHTTPCookieName, self.cookieValue, NSHTTPCookieValue, nil]]; // 加入cookie [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie]; ```
2. 如果在第一次请求的时候需要在HTTPRequest 通过setValueForKey设置 HeaderValue
2. WKWebview
在使用WKWebview的时候也是需要分两种情况传递:
- 1.HTTPRequest 请求URL的时候携带 如后端PHP获取 cookie
2.注入js 目的是让前端从页面里边获取到cookie 可以通过在document.cookie 设置 通过WKWebview 初始化时候把js传递过去
`
WKUserScript * cookieScript = [[WKUserScript alloc] initWithSource: cookieValue injectionTime:WKUserScriptInjectionTimeAtDocumentStart forMainFrameOnly:NO];
3.NSHTTPCookieStorage 似乎不携带没问题,因为我们目前没有通过这个传递cookie
网上参考别人的方法是要实现下面几个步骤,但是我们项目并没有按照这三种必要方式,但是可以做个参考:
WKWebview三个处理步骤: (1)iOS11,WKHTTPCookieStore 直接传递。(如果是只支持iOS11,下面两步可以不做); (2)iOS8-iOS10, js注入; (3)PHP携带cookie方式
