ios - WKWebView session 已过期

Question

我有一个在普通网页上工作的 URL，但嵌入在 WKWebView 中，我总是得到错误 session 过期。有什么方法可以在此 WKWebView 上启用 cookie？

Answer 1

您可以从响应中保存 cookie

- (void)webView:(WKWebView *)webView decidePolicyForNavigationResponse:(WKNavigationResponse *)navigationResponse decisionHandler:(void (^)(WKNavigationResponsePolicy))decisionHandler {
NSDictionary *headers = [(NSHTTPURLResponse *)navigationResponse.response allHeaderFields];
    if ([headers objectForKey:@"Set-Cookie"] != nil) {
        _cookie = [headers objectForKey:@"Set-Cookie"];
    }
    decisionHandler(WKNavigationResponsePolicyAllow);
}

并在请求中设置cookie

_request = [[NSMutableURLRequest alloc] initWithURL:url];
[_request setValue:_cookie forHTTPHeaderField:@"Cookie"];
[_webView loadRequest:_request];
