自苹果宣布2017年1月1日开始强制使用https以来,htpps慢慢成为大家讨论的对象之一,不是说此前https没有出现,只是这一决策让得开发者始料未及,博主在15年的时候就做过https的接口,深知此坑之深,原因就是自身对这方面知识不了解加上网上的资料少,除此外还有博客不知对错就互相转载,导致当时网上几乎找不到能用的代码,这一点,博主说的毫不夸张。
鉴于此,博主一直想填一下这个坑,多增加一些正确的代码,来供广大开发者使用,后来一直被搁置,经过尝试后,博主现将整理好的代码发布在这里,希望能帮到焦急寻找的开发者。
1.先来说说老的AFNetworking2.x怎么来实现的
博主在网上看过几篇帖子,其中说的一些方法是正确的,但是却并不全对,由于那几篇博客几乎一样,博主不能确定最早的那篇是谁写的,所以就重新在下面说明下方法:
1)倒入client.p12证书;
2)在plist文件做如图配置:

3)在AFNetworking中修改一个类:

找到这个文件,在里面增加一个方法:
- (OSStatus)extractIdentity:(CFDataRef)inP12Data toIdentity:(SecIdentityRef*)identity {
OSStatus securityError = errSecSuccess;
CFStringRef password = CFSTR("证书密码");
const void *keys[] = { kSecImportExportPassphrase };
const void *values[] = { password };
CFDictionaryRef options = CFDictionaryCreate(NULL, keys, values, 1, NULL, NULL);
CFArrayRef items = CFArrayCreate(NULL, 0, 0, NULL);
securityError = SecPKCS12Import(inP12Data, options, &items);
if (securityError == 0)
{
CFDictionaryRef ident = CFArrayGetValueAtIndex(items,0);
const void *tempIdentity = NULL;
tempIdentity = CFDictionaryGetValue(ident, kSecImportItemIdentity);
*identity = (SecIdentityRef)tempIdentity;
}
if (options) {
CFRelease(options);
}
return securityError;
}
再修改一个方法:
用下面的这段代码替换NSURLConnectionDelegate中的同名代码,
- (void)connection:(NSURLConnection *)connection
willSendRequestForAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
NSString *thePath = [[NSBundle mainBundle] pathForResource:@"client" ofType:@"p12"];
//倒入证书 NSLog(@"thePath===========%@",thePath);
NSData *PKCS12Data = [[NSData alloc] initWithContentsOfFile:thePath];
CFDataRef inPKCS12Data = (__bridge CFDataRef)PKCS12Data;
SecIdentityRef identity = NULL;
// extract the ideneity from the certificate
[self extractIdentity :inPKCS12Data toIdentity:&identity];
SecCertificateRef certificate = NULL;
SecIdentityCopyCertificate (identity, &certificate);
const void *certs[] = {certificate};
// CFArrayRef certArray = CFArrayCreate(kCFAllocatorDefault, certs, 1, NULL);
// create a credential from the certificate and ideneity, then reply to the challenge with the credential
//NSLog(@"identity=========%@",identity);
NSURLCredential *credential = [NSURLCredential credentialWithIdentity:identity certificates:nil persistence:NSURLCredentialPersistencePermanent];
// credential = [NSURLCredential credentialWithIdentity:identity certificates:(__bridge NSArray*)certArray persistence:NSURLCredentialPersistencePermanent];
[challenge.sender useCredential:credential forAuthenticationChallenge:challenge];
}
