In order to validate a domain name for self signed certificates, you MUST use pinning，AFNetWorking使用自簽證書時出現(xiàn)問題。

上述問題的解決方法：

//如果是需要驗(yàn)證自建證書，需要設(shè)置為YES

securityPoliy.allowInvalidCertificates =YES;

securityPoliy.validatesDomainName =NO;//不驗(yàn)證證書的域名

HTTPS步驟：

1.從服務(wù)器要來.crt格式的證書，然后用Mac鑰匙串打開，然后導(dǎo)出.cer格式的證書

2.把.cer證書導(dǎo)入程序的 NSBundle中。

驗(yàn)證證書的代碼：

NSString*cerPath = [[NSBundlemainBundle] pathForResource:@"test"ofType:@"cer"];

NSData*cerData = [NSDatadataWithContentsOfFile:cerPath];

NSSet*cerSet = [[NSSetalloc]initWithObjects:cerData,nil];

AFSecurityPolicy *securityPoliy = [AFSecurityPolicy defaultPolicy];

//allowInvalidCertificates 是否允許無效證書（也就是自建的證書），默認(rèn)為NO

//如果是需要驗(yàn)證自建證書，需要設(shè)置為YES

securityPoliy.allowInvalidCertificates =YES;

securityPoliy.validatesDomainName =NO;

//設(shè)置證書

[securityPoliy setPinnedCertificates:cerSet];

[dxClient setSecurityPolicy:securityPoliy];
