苹果关于微信网页支付和支付宝支付遇到的一些问题

1.微信网页支付,支付宝网页支付(现在都是用wkwebview,就不在写关于webview的了)

static const NSString *CompanyFirstDomainByWeChatRegister = @"com.cn";

// 在收到响应后，决定是否跳转

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

NSLog(@"在收到响应后：%@",navigationResponse.response.URL.absoluteString);

//允许跳转

decisionHandler(WKNavigationResponsePolicyAllow);

//不允许跳转

//decisionHandler(WKNavigationResponsePolicyCancel);

}

- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler

{

// 如果是跳转一个新页面

if (navigationAction.targetFrame == nil) {

NSString *str = [navigationAction.request.URL absoluteString];;

if ([str rangeOfString:@"outjbtmwv"].location != NSNotFound) {

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];

}else{

[webView loadRequest:navigationAction.request];

}

NSURLRequest *request = navigationAction.request;

NSString *scheme = [request.URL scheme];

// decode for all URL to avoid url contains some special character so that it wasn't load.

NSString *absoluteString = [navigationAction.request.URL.absoluteString stringByRemovingPercentEncoding];

NSLog(@"Current URL is %@",absoluteString);

static NSString *endPayRedirectURL = nil;

NSString *wxpayurl = @"https://wx.tenpay.com/cgi-bin/mmpayweb-bin/checkmweb";

//这个地址最好加密一下预防苹果商店上线检测到如果嫌麻烦不想写简单拆分一下在拼接一下字符串也可以

if ([absoluteString hasPrefix:wxpayurl] && ![absoluteString hasSuffix:[NSString stringWithFormat:@"redirect_url=ceshi.%@://",CompanyFirstDomainByWeChatRegister]]) {

//[NSString stringWithFormat:@"redirect_url=ceshi.%@://",CompanyFirstDomainByWeChatRegister]

//这里其实是你的微信商户的域名根据自己的商户域名自行配置比如 http://ceshi.com.cn/

decisionHandler(WKNavigationActionPolicyCancel);

NSString *redirectUrl = nil;

if ([absoluteString containsString:@"redirect_url="]) {

NSRange redirectRange = [absoluteString rangeOfString:@"redirect_url"];

endPayRedirectURL = [absoluteString substringFromIndex:redirectRange.location+redirectRange.length+1];

redirectUrl = [[absoluteString substringToIndex:redirectRange.location] stringByAppendingString:[NSString stringWithFormat:@"redirect_url=ceshi.%@://",CompanyFirstDomainByWeChatRegister]];

}else {

redirectUrl = [absoluteString stringByAppendingString:[NSString stringWithFormat:@"&redirect_url=ceshi.%@://",CompanyFirstDomainByWeChatRegister]];

}

NSMutableURLRequest *newRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:redirectUrl] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:XDX_URL_TIMEOUT];

newRequest.allHTTPHeaderFields = request.allHTTPHeaderFields;

newRequest.URL = [NSURL URLWithString:redirectUrl];

[webView loadRequest:newRequest];

return;

}

// Judge is whether to jump to other app.

//配置一下程序里面的URL Schemes字段

if (![scheme isEqualToString:@"https"] && ![scheme isEqualToString:@"http"]) {

decisionHandler(WKNavigationActionPolicyCancel);

if ([scheme isEqualToString:@"ceshiwxjump"]) {

if (endPayRedirectURL) {

[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:endPayRedirectURL] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:20]];

}

}else if ([scheme isEqualToString:[NSString stringWithFormat:@"ceshi.%@",CompanyFirstDomainByWeChatRegister]]) {

}

NSString* reqUrl = request.URL.absoluteString;

// if ([reqUrl hasPrefix:@"alipays://"] || [reqUrl hasPrefix:@"alipay://"])

//支付宝

if ([reqUrl hasPrefix:@"alipays"] || [reqUrl hasPrefix:@"alipay"]) {

//替换fromAppUrlScheme 为本APP的UrlSheme

// NSString *newStr = [self changeScheme:request.URL.absoluteString];

// NSURL *url = [NSURL URLWithString:newStr];

NSString *payStr = @"alipays";

//ceshiSchemes 自己项目的URl Schemes 根据自己的项目自行配置

NSString *strUrl = [reqUrl stringByReplacingOccurrencesOfString:payStr withString:@"ceshiSchemes"];

NSURL *url = [NSURL URLWithString:strUrl];

[[UIApplication sharedApplication]openURL:url];

//bSucc是否成功调起支付宝

}

BOOL canOpen = [[UIApplication sharedApplication] canOpenURL:request.URL];

if (canOpen) {

[[UIApplication sharedApplication] openURL:request.URL];

}

return;

}

decisionHandler(WKNavigationActionPolicyAllow);

}

//配置微信的URl Schemes 这个Schemes 就用你的微信商户域名用于微信支付成功之后跳转返回自己的APP使用

//对于微信返回之后网页刷新的问题可以在AppDelegate里面设置

// NOTE: 9.0以后使用新API接口

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString*, id> *)options

{

//支付支付返回检测其实支付宝用不到这个方法因为支付宝网页支付成功后台可以设在支付成功之后刷新的网页不用前端去处理,具体问题咨询一下写网页的同事 .

//有需要的就这个方法去刷新界面

if ([url.host isEqualToString:@"safepay"]) {

//跳转支付宝钱包进行支付，处理支付结果

[[NSNotificationCenter defaultCenter] postNotificationName:@"refreshZFH5Pay" object:@"1"];

}

//微信网页支付返回监听这个方法是为了有的网页支付成功之后需要刷新网页改变网页内容这个只能监听到从微信返回并不能检测你网页是支付成功

//ceshi.com.cn 自己微信的商户域名根据自己的微信商户域名自行配置

if ([url.scheme containsString:@"ceshi.com.cn"]) {

//通知方法不做多余解释了

[[NSNotificationCenter defaultCenter] postNotificationName:@"refreshWXH5Pay" object:@"1"];

}

return YES;
