ios – 如何在uiwebview中调用https url？

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
