Nodejs创建HTTPS服务器

系统环境

win7 64bit

IP: 192.168.1.13

Nodejs:v0.10.5

Npm:1.2.19

创建express的开发环境

~ D:\workspace\javascript>express -e  nodejs-https
~ D:\workspace\javascript>cd nodejs-https && npm install

我本地已经安装了git客户端msysgit，其中包括了openssl程序。

openssl生成证书文件

#生成私钥key文件：
~ D:\workspace\javascript\nodejs-https>openssl genrsa -out privatekey.pem 1024
Generating RSA private key, 1024 bit long modulus

#通过私钥生成CSR证书签名
~ D:\workspace\javascript\nodejs-https>openssl req -new -key privatekey.pem -out certrequest.csr
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:CN
State or Province Name (full name) [Some-State]:Beijing
Locality Name (eg, city) []:Beijing
Organization Name (eg, company) [Internet Widgits Pty Ltd]:fens.me
Organizational Unit Name (eg, section) []:fens.me
Common Name (eg, YOUR name) []:Conan Zhang
Email Address []:bsspirit@gmail.com

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:

Getting Private key

新生成了3个文件：certificate.pem, certrequest.csr, privatekey.pem

~ D:\workspace\javascript\nodejs-https>ls -l

-rwx------  1 4294967295 mkpasswd 877 Dec 14 10:53 app.js

drwx------+ 1 4294967295 mkpasswd   0 Dec 14 10:53 views

privatekey.pem: 私钥

certrequest.csr: CSR证书签名

certificate.pem: 证书文件

修改启动文件：app.js

~ vi app.js

//最下面
var https = require('https')
,fs = require("fs");

var options = {
key: fs.readFileSync('./privatekey.pem'),
cert: fs.readFileSync('./certificate.pem')
};

https.createServer(options, app).listen(3011, function () {
console.log('Https server listening on port ' + 3011);
});

启动服务器：

~ D:\workspace\javascript\nodejs-https>node app.js

Express server listening on port 3000
Https server listening on port 3011

打开浏览器：HTTP访问




HTTPS访问




查看证书




由于我们证书是自己创建的，没有经过第三方机构的验证，因此会出现警告的提示。大家可以去有资质的网络运营商，去申请自己的证书。比如：godaddy
SSL Certificates，优惠码：WOWfensme

这样我们就在win7完整的HTTPS服务器创建。

3. 用Nodejs创建HTTPS服务器(Linux)

创建过程与win7类似

系统环境

Linux: Ubuntu 12.04.2 LTS 64bit deskop

IP: 192.168.1.20

Nodejs: npm 1.2.21

node v0.11.2

创建express项目

~ cd /home/conan/nodejs
~ express -e  nodejs-https
~ cd nodejs-https
~ sudo npm install

用openssl生成证书文件

~ openssl version -a
OpenSSL 1.0.1 14 Mar 2012
built on: Tue Jun  4 07:26:06 UTC 2013
platform: debian-amd64
options:  bn(64,64) rc4(16x,int) des(idx,cisc,16,int) blowfish(idx)
compiler: cc -fPIC -DOPENSSL_PIC -DZLIB -DOPENSSL_THREADS -D_REENTRANT -DDSO_DLFCN -DHAVE_DLFCN_H -m64 -DL_ENDIAN -DTERMIO -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -Werror=format-security -D_FORTIFY_SOURCE=2 -Wl,-Bsymbolic-functions -Wl,-z,relro -Wa,--noexecstack -Wall -DOPENSSL_NO_TLS1_2_CLIENT -DOPENSSL_MAX_TLS1_2_CIPHER_LENGTH=50 -DMD32_REG_T=int -DOPENSSL_IA32_SSE2 -DOPENSSL_BN_ASM_MONT -DOPENSSL_BN_ASM_MONT5 -DOPENSSL_BN_ASM_GF2m -DSHA1_ASM -DSHA256_ASM -DSHA512_ASM -DMD5_ASM -DAES_ASM -DVPAES_ASM -DBSAES_ASM -DWHIRLPOOL_ASM -DGHASH_ASM
OPENSSLDIR: "/usr/lib/ssl"

~ openssl genrsa -out privatekey.pem 1024
~ openssl req -new -key privatekey.pem -out certrequest.csr
~ openssl x509 -req -in certrequest.csr -signkey privatekey.pem -out certificate.pem

修改文件app.js

~ vi app.js

//在最下面
var https = require('https')
,fs = require("fs");

var options = {
key: fs.readFileSync('./privatekey.pem'),
cert: fs.readFileSync('./certificate.pem')
};

https.createServer(options, app).listen(3011, function () {
console.log('Https server listening on port ' + 3011);
});

启动服务器

~ node app.js

Express server listening on port 3000
Https server listening on port 3011

打开浏览器：

4. 抓取请求，验证加密

为了验证数据在传输过程中是加密的，我们用wireshark抓取网络包。

HTTP请求：http://192.168.1.20:3000/users?a=111




HTTPS请求：https://192.168.1.20:3011/users?a=112




在HTTP下面，URL请求的参数是被暴露的。在HTTPS下面，URL的请求参数是被加密的。因此，希望需要填写个人信息，及在线支付的网站，都把HTTPS服务器搭建起来。防止私密数据，在网络传输过程中被获取。
