UIWebView和WKWebView设置Cookies

UIWebView设置cookie

1.在webViewDidFinishLoad中获取cookie并通过NSUserDefaults保存

#pragma mark - UIWebViewDelegate
-(void)webViewDidFinishLoad:(UIWebView *)webView{

    NSArray *nCookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];
    NSHTTPCookie *cookie;
    for (id c in nCookies)
    {
        if ([c isKindOfClass:[NSHTTPCookie class]])
        {
            
            cookie=(NSHTTPCookie *)c;
            SQLog(@"cookieName:%@,value:%@",cookie.name,cookie.value);
            if ([cookie.name isEqualToString:@"userList"]) {
                NSNumber *sessionOnly = [NSNumber numberWithBool:cookie.sessionOnly];
                NSNumber *isSecure = [NSNumber numberWithBool:cookie.isSecure];
                NSArray *cookies = [NSArray arrayWithObjects:cookie.name, cookie.value, sessionOnly, cookie.domain, cookie.path, isSecure, nil];
                [[NSUserDefaults standardUserDefaults] setObject:cookies forKey:@"cookie"];
                [[NSUserDefaults standardUserDefaults] synchronize];
                break;
            }
        }
    }
}

2.再请求网络之前加入已经保存在本地的cookie

//判断是否沙盒中是否有Cookie这个值
    if ([[[[NSUserDefaults standardUserDefaults] dictionaryRepresentation] allKeys] containsObject:@"cookie"]) {
        //获取cookies：程序起来之后，uiwebview加载url之前获取保存好的cookies，并设置cookies，
        NSArray *cookies =[[NSUserDefaults standardUserDefaults]  objectForKey:@"cookie"];
        NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary];
        [cookieProperties setObject:[cookies objectAtIndex:0] forKey:NSHTTPCookieName];
        [cookieProperties setObject:[cookies objectAtIndex:1] forKey:NSHTTPCookieValue];
        [cookieProperties setObject:[cookies objectAtIndex:3] forKey:NSHTTPCookieDomain];
        [cookieProperties setObject:[cookies objectAtIndex:4] forKey:NSHTTPCookiePath];
        NSHTTPCookie *cookieuser = [NSHTTPCookie cookieWithProperties:cookieProperties];
        [[NSHTTPCookieStorage sharedHTTPCookieStorage]  setCookie:cookieuser];
    }

WKWebVIew设置cookie

1.获取cookie

- (void)webView:(WKWebView *)webView decidePolicyForNavigationResponse:(WKNavigationResponse *)navigationResponse decisionHandler:(void (^)(WKNavigationResponsePolicy))decisionHandler {
    
    NSHTTPURLResponse *response = (NSHTTPURLResponse *)navigationResponse.response;
    NSArray *cookies =[NSHTTPCookie cookiesWithResponseHeaderFields:[response allHeaderFields] forURL:response.URL];
    for (NSHTTPCookie *cookie in cookies) {
        [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
    }
    
    decisionHandler(WKNavigationResponsePolicyAllow);
}

2.设置请求头

NSArray *cookies = [NSHTTPCookieStorage sharedHTTPCookieStorage].cookies;
    NSDictionary *requestHeaderFields = [NSHTTPCookie requestHeaderFieldsWithCookies:cookies];
    //设置请求头
    _SQMutableRequest.allHTTPHeaderFields = requestHeaderFields;
