WKWebView捕获HTTP错误代码 [英] WKWebView catch HTTP error codes

问题描述

当我从我的页面返回任何http错误（目前为401，但我尝试了404等）

When i return any http error from my page (currently 401, but i tried also with 404 and so on)

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

代表WKWebView的回调不返回错误

the delegate callbacks of the WKWebView don't return an error

- (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？

推荐答案

关键是等待响应，然后检查对象，没有调用http代码的错误

The key was to wait for the response and then inspect the object, no error is called on http code

- (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);
}
