Answer 1

Ini tiada kaitan dengan AFNetworking kod=-1012 ialah mesej ralat NSURLError yang disediakan oleh sistem. Terdapat jadual perbandingan http://blog.csdn.net/yesjava/article/details/8056681.
NSURLErrorUserCancelledAuthentication = -1012. Pengguna membatalkan pengesahan.
Anda akan tahu sebabnya selepas mencari.

Answer 2

1. Pelayan DNS untuk akses wayarles dan akses selular adalah berbeza. Melihat kepada mesej ralat, pelayan yang anda akses telah mendayakan SSL dan menggunakan sijil yang dijana sendiri 2.x menghadapi masalah yang serupa, di bawah versi 3.x:
2.1 pengubahsuaian kod:

//使用默认的security policy, 注释掉类似代码：
//sessionMgr.securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeNone];
//以下和AFNetworking 2.x相同
sessionMgr.securityPolicy.allowInvalidCertificates = YES;
//以下是AFNetworking 3.x 下需要的
sessionMgr.securityPolicy.validatesDomainName = NO;

2.2 Info.plist Sertai ATS:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

3. Contoh kod:

//#自生成证书

-(IBAction)clickOnSSLWithJSON:(id)sender {
    NSLog(@"ssl with json");
    
    NSURL *url = [NSURL URLWithString:@"https://192.168.1.6:3000"];
    AFHTTPSessionManager *sessionMgr=[[AFHTTPSessionManager alloc]initWithBaseURL:url];
    sessionMgr.responseSerializer = [AFHTTPResponseSerializer serializer];
 
    sessionMgr.responseSerializer.acceptableContentTypes = [[NSSet alloc] initWithObjects:@"text/html",nil];
    //in this case, Info.plist should be added with keys 'NSAppTransportPolicy' and 'NSAllowsArbitraryLoads',
    //and security policy  should be used with default.
    //following setting is same as AFNetworking 2.x
    sessionMgr.securityPolicy.allowInvalidCertificates = YES;
    //following setting is specified for AFNetworking 3.x
    sessionMgr.securityPolicy.validatesDomainName = NO;
    [sessionMgr GET:@"" parameters:nil progress:nil
            success: ^(NSURLSessionDataTask * _Nonnull task, id _Nullable result){
                //NSUTF8StringEncoding should be encoded for response data.
                NSLog(@"ok:\n%@",[[NSString alloc]initWithData:result encoding:NSUTF8StringEncoding]);
            }
            failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error)
            {
                NSLog(@"error:\n%@",error);
            }];
}
