ios - WKWebView 捕获 HTTP 错误代码

Question

当我从我的页面返回任何 http 错误时(目前是 401，但我也尝试过 404 等等)

http://min60.com/__personal/e401.php

WKWebView 的委托(delegate)回调不返回错误

- (void)webView:(WKWebView *)webView didFailProvisionalNavigation:(WKNavigation *)navigation withError:(NSError *)error

- (void)webView:(WKWebView *)webView didFailNavigation:(null_unspecified WKNavigation *)navigation withError:(NSError *)error {

如何捕获此类错误？

Answer 1

关键是等待响应然后检查对象，http代码没有调用错误

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

    if ([navigationResponse.response isKindOfClass:[NSHTTPURLResponse class]]) {

        NSHTTPURLResponse * response = (NSHTTPURLResponse *)navigationResponse.response;
        if (response.statusCode == 401) {

            // here we go

        }

    }
    decisionHandler(WKNavigationResponsePolicyAllow);
}
