从WKWebview中检索HTTP响应标头

Question

我需要从WKWebview的请求中读取响应HTTP标头。我需要根据服务器发送的某些自定义标题执行自定义。无法在响应数据中添加此信息。

我无法在文档中找到任何条目，也无法在此处找到以前的问题。有没有办法做到这一点？

Answer 1

看起来你可以访问从WKNavigationDelegate方法webView:decidePolicyFor:decisionHandler:响应。

设置一些对象为WKWebView的navigationDelegate，并添加以下方法：

- (void)webView:(WKWebView *)webView decidePolicyForNavigationResponse:(WKNavigationResponse *)navigationResponse decisionHandler:(void (^)(WKNavigationResponsePolicy))decisionHandler { 
    NSDictionary *headers = ((NSHTTPURLResponse *)navigationResponse.response).allHeaderFields; 

    decisionHandler(WKNavigationResponsePolicyAllow); 
} 

Answer 2

从代表方法，您可以检索(WKNavigationResponse*)navigationResponse。而从navigationResponse对象，你可以得到响应本身：

- (void)webView:(WKWebView *)webView decidePolicyForNavigationResponse:(WKNavigationResponse *)navigationResponse decisionHandler:(void (^)(WKNavigationResponsePolicy))decisionHandler { 

    NSHTTPURLResponse * response = (NSHTTPURLResponse *)navigationResponse.response; 

}

雨燕3.1的版本NobodyNada的回答：

没有力量投

func webView(_ webView: WKWebView, decidePolicyFor navigationResponse: WKNavigationResponse, decisionHandler: @escaping (WKNavigationResponsePolicy) -> Void) { 
    if let response = navigationResponse.response as? HTTPURLResponse { 
     let headers = response.allHeaderFields 
     //do something with headers 
    } 
    decisionHandler(.allow) 
} 

用力投：

func webView(_ webView: WKWebView, decidePolicyFor navigationResponse: WKNavigationResponse, decisionHandler: @escaping (WKNavigationResponsePolicy) -> Void) { 
    let headers = (navigationResponse.response as! HTTPURLResponse).allHeaderFields 
    //do something with headers 
    decisionHandler(.allow) 
}
