我有一个HTTPS网址.它正在加载在iPhone Safari中,但在UIWebView中无法使用.
错误是：
NSURLConnection/CFURLConnection HTTP load Failed (kcfStreamErrorDomainSSL,-9813)
如何解决这个问题？
解决方法
我下面已经解释了如何在UIWebview中访问https url,它将帮助您清除问题,因为它适用于我.
调用http与https url相同.
但是,如果您使用自签名证书,则需要添加一些附加代码.因为默认情况下,iOS将拒绝所有不受信任的https连接.
限制不可靠的连接是非常好的默认行为,任何禁用此功能都是非常危险的.因此,我们将显示一个警报,因为我们将绕过默认行为.
-(BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace; -(void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge;
以上两种方法允许我们为可信连接提供我们自己的认证机制
#import "ClassCon.h"
// For now,I've hard coded the IP address of my trusted server.
#define TRUSTED_HOST @"192.168.1.2"
@implementation ClassCon {
NSMutableData *contentData;
NSURLConnection *conn;
}
-(void) loadContent {
contentData = [NSMutableData data];
NSString *contentURL = @"our url";
conn = [[NSURLConnection alloc] initWithRequest:
[NSURLRequest requestWithURL:[NSURL URLWithString:contentURL]] delegate:self];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
[contentData appendData:data];
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
NSLog(@"Bad: %@",[error description]);
ContentResponse *response = [[ContentResponse alloc]initWithRc:-999 andDescr:@"error" andAction:0];
conn = nil;
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
NSString *loadedContent = [[NSString alloc] initWithData:
contentData encoding:NSUTF8StringEncoding];
NSLog(@"Loaded content: %@",loadedContent);
}
// ------------ ByPass ssl starts ----------
-(BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:
(NSURLProtectionSpace *)protectionSpace {
return [protectionSpace.authenticationMethod
isEqualToString:NSURLAuthenticationMethodServerTrust];
}
-(void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:
(NSURLAuthenticationChallenge *)challenge {
if (([challenge.protectionSpace.authenticationMethod
isEqualToString:NSURLAuthenticationMethodServerTrust])) {
if ([challenge.protectionSpace.host isEqualToString:TRUSTED_HOST]) {
NSLog(@"Allowing bypass...");
NSURLCredential *credential = [NSURLCredential credentialForTrust:
challenge.protectionSpace.serverTrust];
[challenge.sender useCredential:credential
forAuthenticationChallenge:challenge];
}
}
[challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}
// -------------------ByPass ssl ends
@end
希望这可以帮助
