最近袍暴，app嵌入了一個(gè)H5模塊填帽，H5里面加入了微信支付的功能执泰。在發(fā)起微信支付的時(shí)候是通過(guò)weixin://的協(xié)議方式的，在UIWebView中可以正常調(diào)起微信發(fā)起支付嗡善，但支付成功會(huì)跳轉(zhuǎn)Safari瀏覽器然后加載支付成功頁(yè)面辑莫，WKWebView不能識(shí)別這種協(xié)議，不會(huì)跳轉(zhuǎn)微信罩引。

let scheme = request.url?.scheme
let absoluteString = request.url?.absoluteString.removingPercentEncoding
DPrint(absoluteString)
// 設(shè)置返回Url：在Info.plist中設(shè)置的URL Schemes
let appScheme = ""
let redirect_url = "redirect_url=zxl.\(appScheme)://"
// 判斷是否是微信支付請(qǐng)求
let hasPrefix = absoluteString?.hasPrefix("https://wx.tenpay.com/cgi-bin/mmpayweb-bin/checkmweb")
let hasSuffix = absoluteString?.hasSuffix(redirect_url)
if hasPrefix! && hasSuffix == false {
decisionHandler(.cancel)
var requestUrl = absoluteString
let range = requestUrl?.range(of: "&redirect_url=")
if (range != nil) {
let subRange = (range?.lowerBound)!..<(requestUrl?.endIndex)!
// 保存支付成功頁(yè)面路徑伺帘，支付成功后加載
WeiXinPayRedirectURL = "https://hlht.echargenet.com/perhlhth5/#/views/rechargeSuccess"

}
requestUrl = requestUrl! + "&" + redirect_url
// 重新發(fā)送請(qǐng)求
let newRequest = NSMutableURLRequest(url: URL(string: requestUrl!)!, cachePolicy: NSURLRequest.CachePolicy.useProtocolCachePolicy, timeoutInterval: TIMEOUT)
newRequest.allHTTPHeaderFields = request.allHTTPHeaderFields
webView.load(newRequest as URLRequest)

if UIApplication.shared.canOpenURL(request.url!) {
UIApplication.shared.open(request.url!, options: [UIApplication.OpenExternalURLOptionsKey.init(rawValue: "hello") : "world"]) { (isT) in
DPrint((isT ? "成功" : "失敗"))

@objc func webViewWXPaySuccess(_ notification:Notification) {
DispatchQueue.global().async {
DispatchQueue.main.async {
let request = NSMutableURLRequest(url: URL(string: self.WeiXinPayRedirectURL)!)
request.httpMethod = "GET"
request.setValue("zxl.**://", forHTTPHeaderField: "Referer")
self.webView.load(request as URLRequest)
