步骤:
1.创建私钥与证书
2.搭建https-Node服务器
3.创建iOS-https项目
4.使用Charles工具抓包验证
私钥、证书
打开终端
//进入桌面
$ cd ~/Desktop/
//生产私钥
$ openssl genrsa 2048 > rsa_private_key.pem
//由私钥生产证书请求(签名)
$ openssl req -new -key rsa_private_key.pem -out certificate_request.csr
//通过私钥文件和CSR证书签名生成证书文件(服务器证书)
$ openssl x509 -req -days 365 -in certificate_request.csr -signkey rsa_private_key.pem -out cert.pem
//转换证书(iOS端证书)
$ openssl x509 -in cert.pem -out cert_ios.cer -outform der
//此时桌面上得到了我们需要的三个文件
rsa_private_key.pem(私钥)
cert.pem(证书用于服务器端)
cert_ios.cer(证书用于iOS端)
Node服务器
//index.js代码
var https = require('https');
var fs = require('fs');
var options = {
key: fs.readFileSync('./rsa_private_key.pem'),
cert: fs.readFileSync('./cert.pem')
};
var params = {
hi : 'Hello World!',
hello : 'Hello Node!'
}
var server = https.createServer(options ,function(req, res){
res.writeHead(200, {'Content-Type': 'application/json'});
res.end(JSON.stringify(params));
}).listen(3000);
//命令行进入server目录
$ cd server
//启动服务
$ node index.js
打开浏览器输入https://127.0.0.1:3000查看是否服务器已启动
iOS-Https工程
Xcode创建iOS-Https工程,使用Cocoapods安装AFNetworking库,将cert_ios.cer证书拖至项目中(勾选copy)。
【运行项目,有以下情景】
情景1.不安全(使用Charles的Https抓取可以解析所有信息)
客户端不验证服务器端证书真伪
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.securityPolicy.allowInvalidCertificates = YES;
manager.securityPolicy.validatesDomainName = NO;
NSString *url = @"https://192.168.1.106:3000";//局域网真机调试
// NSString *url = @"https://127.0.0.1:3000";//模拟器调试
[manager GET:url parameters:@{@"name":@"ZZZ", @"age":@32} progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(@"%@",responseObject);
// 2017-06-21 07:19:50.880 Https[3169:138713] {
// hello = "Hello Node!";
// hi = "Hello World!";
// }
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
}];
情景2:安全(Charles的Https只能抓取到ip和端口信息)
客户端验证服务器端证书真伪
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
//加载项目中的所有.cer文件
NSSet *certificates = [AFSecurityPolicy certificatesInBundle:[NSBundle mainBundle]];
//AFSSLPinningModePublicKey:公钥验证
//AFSSLPinningModeCertificate:证书验证
manager.securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModePublicKey withPinnedCertificates:certificates];
manager.securityPolicy.allowInvalidCertificates = YES;
manager.securityPolicy.validatesDomainName = NO;
NSString *url = @"https://192.168.1.106:3000";//局域网真机调试
// NSString *url = @"https://127.0.0.1:3000";//模拟器调试
[manager GET:url parameters:@{@"name":@"ZZZ", @"age":@32} progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(@"%@",responseObject);
// 2017-06-21 07:19:50.880 Https[3169:138713] {
// hello = "Hello Node!";
// hi = "Hello World!";
// }
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
}];
