afnetworking使用https

Posted 2022-11-06 蜡笔小斌

背景：

1. 在开发环境下，HTTPS一般使用自行颁发的证书
2. AFNetworking3 使用HTTPS协议时，需要针对自行颁发的证书作一定配置
3. 我在配置过程中发现网上的信息多少都有疏漏

1.nginx HTTPS配置

1.1使用以下命令生成server.key,server.csr,server.crt三个文件
openssl req -new -nodes -keyout server.key -out server.csr

openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

1.2Nginx配置文件例子

upstream api 
    server 127.0.0.1:4000 fail_timeout=0;


server 
    listen 3000;
    server_name localhost;

    root /vagrant/grape-api/public;

    try_files $uri/index.html $uri @api;

    location @api 
        proxy_pass http://api;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;
    

    error_page 500 502 503 504 /500.html;
    client_max_body_size 4G;
    keepalive_timeout 10;

    ！！！注意这里一系列的ssl配置
    ssl on;
    ssl_certificate /home/vagrant/server.crt;    这是上一步生成的crt文件路径
    ssl_certificate_key /home/vagrant/server.key;这是上一步生成的key文件路径
    ssl_session_timeout 5m;
    ssl_protocols SSLv2 SSLv3 TLSv1;
    ssl_ciphers  HIGH:!aNULL:!MD5;
    ssl_prefer_server_ciphers   on;

重启Nginx，就只支持通过HTTPS访问了

2. AFNetworking3.0 调用例子

2.1

使用如下命令获取https.cer文件

openssl s_client -connect 127.0.0.1:443 </dev/null 2>/dev/null | openssl x509 -outform DER > https.cer

把cer文件放入ios应用的bundle中，然后使用如下代码进行配置

    //afnetworking对于自行颁发证书的配置
    NSURL *baseURL = [NSURL URLWithString: @"https://127.0.0.1:3000/v1"];
    NSString *cerPath = [[NSBundle mainBundle] pathForResource:@"https" ofType:@"cer"];
    NSData * certData =[NSData dataWithContentsOfFile:cerPath];
    NSSet * certSet = [[NSSet alloc] initWithObjects:certData, nil];
    AFSecurityPolicy *securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeCertificate];
    [securityPolicy setAllowInvalidCertificates:YES];
    [securityPolicy setPinnedCertificates:certSet];
    [securityPolicy setValidatesDomainName:NO];


    AFHTTPSessionManager * manager = [[AFHTTPSessionManager alloc] initWithBaseURL:baseURL];
    manager.securityPolicy = securityPolicy;
    manager.requestSerializer = [AFJSONRequestSerializer serializer];
    [manager GET:@"users/avatar" parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) 
        NSLog(@"PLIST: %@", responseObject);
     failure:^(NSURLSessionTask *operation, NSError *error) 
        NSMutableData *body = error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey];
        NSString* aStr = [[NSString alloc] initWithData:body encoding:NSUTF8StringEncoding];
        NSLog(@"%@",aStr);
    ];
