Node.js https 以及iOS https请求

话不多说，直入正题。

先说node.js端

证书是我在腾讯云搞得，下载下来即可。上代码
node用的是express模块

var app = require('express')();
var fs = require('fs');
var http = require('http');
var https = require('https');
var privateKey  = fs.readFileSync('3_sallen.cc.key');
var certificate = fs.readFileSync('2_sallen.cc.crt');
var credentials = {key: privateKey, cert: certificate};

var httpServer = http.createServer(app);
var httpsServer = https.createServer(credentials, app);
var PORT = 8000;
var SSLPORT = 8001;

httpServer.listen(PORT, function() {
    console.log('HTTP Server is running on: http://localhost:%s', PORT);
});
httpsServer.listen(SSLPORT, function() {
    console.log('HTTPS Server is running on: https://localhost:%s', SSLPORT);
});

app.get('/user', function(req, res) {
    if(req.protocol === 'https') {
        res.status(200).send('Welcome to sallen');
    }
    else {
        res.status(200).send('Welcome!');
    }
});

好了 下面是ios

后台给的证书crt的话 需要转换成cer

进到证书路径，执行下面语句 openssl x509 -in 你的证书.crt -out 你的证书.cer -outform der 这样你就可以得到cer类型的证书了
sallen是我转换的证书。

我用的是免费证书 所以在ios访问时以下错误，

所以需要在afnetworking里面注释掉下面

当然了 花钱的证书 应该是不需要的。

下面ios代码附上

   NSString *url = @"your address";
   
   NSString *cerPath = [[NSBundle mainBundle] pathForResource:@"sallen" ofType:@"cer"];
   NSData *certData =[NSData dataWithContentsOfFile:cerPath];
   NSSet *certSet = [[NSSet alloc] initWithObjects:certData, nil];
  
   
   AFSecurityPolicy *securityPolicy = [AFSecurityPolicy defaultPolicy];
   // 设置证书
   [securityPolicy setPinnedCertificates:certSet];
   securityPolicy.allowInvalidCertificates = YES;
   securityPolicy.validatesDomainName = YES;
   // 初始化请求的manager对象
   AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
   manager.securityPolicy = securityPolicy;
   manager.responseSerializer = [AFHTTPResponseSerializer serializer];
 
   
   [manager GET:url parameters:nil progress:^(NSProgress * progress){
   } success:^(NSURLSessionDataTask *task, id responseObject) {
       NSArray * array = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableLeaves error:nil];
       NSLog(@"OK === %@",array);
   } failure:^(NSURLSessionDataTask *task, NSError *error) {
       NSLog(@"error ==%@",error.description);
   }];
   ```
