- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler
此代理方法相当于UIWebView的
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
想要在请求的URL中添加头部参数如Token之类的，就是在此方法中拦截URL，添加头部参数
具体方法
- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler {
if (_isCareweeLink) {
BOOL headerIsPresent = [[navigationAction.request allHTTPHeaderFields] objectForKey:@"x-access-ver"]!=nil;
// LSYLOG(@"%@", [navigationAction.request allHTTPHeaderFields]);
if(headerIsPresent){
decisionHandler(WKNavigationActionPolicyAllow);
}else{
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
dispatch_async(dispatch_get_main_queue(), ^{
NSURL *url = [navigationAction.request URL];
NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
[request addValue:_accessVer forHTTPHeaderField:@"x-access-ver"];
if (LsyUserDefault.x_access_token != nil) {
[request addValue:LsyUserDefault.x_access_token forHTTPHeaderField:@"x-access-token"];
}
[webView loadRequest:request];
});
});
decisionHandler(WKNavigationActionPolicyCancel);
}
}else{
decisionHandler(WKNavigationActionPolicyAllow);
}
}
