我现在做得这个项目里面包含了第三方支付，在使用的时候会有部分界面是调用网页来展示的，但是当我使用自带的WebView来加载这些网页的时候，就出错了：NSURLConnection/CFURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9813） 当时还不知道，后面在Mac下的浏览器打开就说什么是私密链接，而且网址是以Https开头的，百度了下，我这才知道原来是SLL没有设置。所以在加载Https的需要先用NSURLConnection来访问站点，然后在验证身份的时候，将该站点设置为可信任站点，最后用WebView重新加载一次就好了！
不多说了，贴代码：
//首先你得声明协议
//然后 你得声明三个全局变量
NSURLRequest*_originRequest;
NSURLConnection*_urlConnection;
BOOL_authenticated;
//再在 你需要用WebView加载网页的地方初始化Request
_originRequest= [NSURLRequestrequestWithURL:[NSURLURLWithString:urlStr]];
[self.allWebViewloadRequest:_originRequest];
//最后就是实现协议函数了
- (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType
{
NSLog(@"Did start loading: %@ auth:%d", [[requestURL]absoluteString],_authenticated);
if(!_authenticated) {
_authenticated=NO;
_urlConnection= [[NSURLConnectionalloc]initWithRequest:_originRequestdelegate:self];
[_urlConnectionstart];
returnNO;
}
returnYES;
}
-(void)webView:(UIWebView*)webView didFailLoadWithError:(NSError*)error{
// 102 == WebKitErrorFrameLoadInterruptedByPolicyChange
NSLog(@"***********error:%@,errorcode=%d,errormessage:%@",error.domain,error.code,error.description);
if(!([error.domainisEqualToString:@"WebKitErrorDomain"] && error.code==102)) {
//当请求出错了会做什么事情
}
}
#pragmamark-NURLConnectiondelegate
-(void)connection:(NSURLConnection*)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge*)challenge
{
NSLog(@"WebController Got auth challange via NSURLConnection");
if([challengepreviousFailureCount]==0)
{
_authenticated=YES;
NSURLCredential*credential=[NSURLCredentialcredentialForTrust:challenge.protectionSpace.serverTrust];
[challenge.senderuseCredential:credentialforAuthenticationChallenge:challenge];
}else
{
[[challengesender]cancelAuthenticationChallenge:challenge];
}
}
-(void)connection:(NSURLConnection*)connection didReceiveResponse:(NSURLResponse*)response
{
NSLog(@"WebController received response via NSURLConnection");
// remake a webview call now that authentication has passed ok.
_authenticated=YES;
[self.allWebViewloadRequest:_originRequest];
// Cancel the URL connection otherwise we double up (webview + url connection, same url = no good!)
[_urlConnectioncancel];
}
// We use this method is to accept an untrusted site which unfortunately we need to do, as our PVM servers are self signed.
- (BOOL)connection:(NSURLConnection*)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace*)protectionSpace
{
return[protectionSpace.authenticationMethodisEqualToString:NSURLAuthenticationMethodServerTrust];
}
//最后还需要一个NSURLRequest(NSURLRequestWithIgnoreSSL)的扩展，.m文件中只需要一个函数就好了。
+ (BOOL)allowsAnyHTTPSCertificateForHost:(NSString*)host
{
returnYES;
}
