注册域名坑：请使用www.xxx.com(别使用abc.m.en.com)这种形式向微信注册，否则无法正常回调处理
使用iOS打开微信支付页面需要设置webview的Referer
Referer一般为http://www.xxx.com或者直接www.xxx.com
在Info中URL Type添加该Referer为打开自己app的scheme
嗯，就这样结束！！！
现的是通过拦截web请求，判断是否为https/http请求，不是则通过scheme方式打开外部页面:标准写法
- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler {
NSURL *url = navigationAction.request.URL;
NSString *scheme = [url scheme];
if (![scheme isEqualToString:@"https"] && ![scheme isEqualToString:@"http"]) {
[[UIApplication sharedApplication] openURL:url];
}
decisionHandler(WKNavigationActionPolicyAllow);
}
打开微信可能遇到的坑
下方代码不但实现页面跳转，还处理了web url不是微信注册的refer问题
- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler {
NSURLRequest *request = navigationAction.request;
NSString *scheme = [request.URL scheme];
//微信支付
if ([scheme isEqualToString:@"weixin"]) {
decisionHandler(WKNavigationActionPolicyCancel);
BOOL canOpen = [[UIApplication sharedApplication] canOpenURL:request.URL];
if (canOpen) {
[[UIApplication sharedApplication] openURL:request.URL];
}
return;
}
NSDictionary *referDict = [[NSUserDefaults standardUserDefaults] objectForKey:@"loadUrlWithRefer"];
if (referDict != nil && [referDict isKindOfClass:[NSDictionary class]]) {
NSString *url = referDict[@"url"];
NSString *refer = referDict[@"refer"];
NSDictionary *headers = [navigationAction.request allHTTPHeaderFields];
NSString * referer = [headers objectForKey:@"Referer"];
BOOL isRightReferer = [referer isEqualToString:refer];
if (isRightReferer) {
decisionHandler(WKNavigationActionPolicyAllow);
} else {
decisionHandler(WKNavigationActionPolicyCancel);
if ([url isEqualToString:[navigationAction.request.URL absoluteString]]) {
NSMutableDictionary * muDict = [[NSMutableDictionary alloc] initWithDictionary:headers];
[muDict setObject:refer forKey:@"Referer"];
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:NSURLRequestReloadIgnoringCacheData timeoutInterval:60.0];
request.allHTTPHeaderFields = muDict;
[webView loadRequest:request];
});
});
}
[[NSUserDefaults standardUserDefaults] removeObjectForKey:@"loadUrlWithRefer"];
return;
}
}
decisionHandler(WKNavigationActionPolicyAllow);
}
loadUrlWithRefer存储的内容为web页面请求的订单信息通过js传递到原生并存储，包括注册微信的url和refer
