AFNetworking访问https出现"NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9813"

       使用AFNetworking来访问http请求非常方便快捷，最简单的请求代码如下：

#import "HSTestHTTPSViewController.h"
#import <AFNetworking/AFNetworking.h>

@interface HSTestHTTPSViewController ()

@end

@implementation HSTestHTTPSViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    NSString *URLString = @"http://localhost:8000";

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    manager.requestSerializer = [AFHTTPRequestSerializer serializer];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];

    [manager GET:URLString parameters:nil progress:nil
          success:^(NSURLSessionDataTask *task, id responseObject) {
              //返回NSData，转化为String输出
              NSString *JSONString = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
              NSLog(@"%@", JSONString);
          }
          failure:^(NSURLSessionDataTask *task, NSError *error) {
              NSLog(@"%@", error);
          }];
}

@end

NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9813)
Error Domain=NSURLErrorDomain Code=-1202 "The certificate for this server is invalid.

     出现以上问题的主要原因是https证书是自签名证书，没有经过第三方机构认证（关于生成自签名证书和nodejs配置自签名证书可以了解《nodejs开发——express配置自签名https服务器》这篇博客）。一个经过认证的证书一般不会出现以上问题。那么在服务端https证书不变的情况下，如何在iOS客户端修复该问题呢？

（1）从服务端那里拿到证书crt后缀文件，我这里的文件名为“file.crt”. (建议看下《nodejs开发——express配置自签名https服务器》)。然后使用该crt文件生成用于iOS的.cer文件，我这里的文件名为“client.cer”.  生成命令如下：

openssl x509 -in file.crt -out client.cer -outform der

（2）然后把client.crt文件复制到iOS项目目录下，然后在Build Phases中的Copy Bundle Resources中选中crt文件进行添加：

（3）然后把AFN的网络请求代码修改如下：主要增加Security设置

#import "HSTestHTTPSViewController.h"
#import <AFNetworking/AFNetworking.h>

@interface HSTestHTTPSViewController ()

@end

@implementation HSTestHTTPSViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    NSString *URLString = @"https://localhost:8001";

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    manager.requestSerializer = [AFHTTPRequestSerializer serializer];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];

    //增加AFSecurityPolicy设置
    AFSecurityPolicy * securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeCertificate];
    securityPolicy.allowInvalidCertificates = YES;
    securityPolicy.validatesDomainName = NO;
    manager.securityPolicy = securityPolicy;

    [manager GET:URLString parameters:nil progress:nil
          success:^(NSURLSessionDataTask *task, id responseObject) {
              //返回NSData，转化为String输出
              NSString *JSONString = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
              NSLog(@"%@", JSONString);
          }
          failure:^(NSURLSessionDataTask *task, NSError *error) {
              NSLog(@"%@", error);
          }];
}

@end
