如何在uiwebview中调用https url？

我在下面解释了如何在UIWebview中访问https url，因为它对我有用，它将帮助您清除问题。

调用http与https url相同。

但是，如果您使用的是自签名证书，则必须添加一些其他代码。由于默认情况下，iOS会拒绝所有不受信任的https连接。

限制不受信任的连接是非常好的默认行为，禁用此行为的风险很高。因此，当我们将绕过默认行为时，我们将显示警报。

-(BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace;

-(void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge;

以上两种方法使我们能够为信任的连接提供我们自己的身份验证机制

#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
