Foreword
Data encrypted transmission, we often come across several methods. One is ciphertext transmission, and the other is plaintext transmission. Ciphertext transmission is to use a key to encrypt the data and use the public key to decrypt the data. The transmission channel can be https. It can be http. The premise of clear text transmission is to establish a secure transmission channel. Here, a certificate is used to protect the security of the channel, and then the data is transmitted in plain text.
The more professional ones can share it later, but here I will introduce the plain text transmission. If nodejs is used to establish a secure channel
Use two libraries, namely urllib and request. The certificate here only introduces the use of pfx files
The method of urllib library
const urllibRequest = (url, method, data, pfx, pass) => {
return new Promise(function(resolve, reject) {
let options = {
data: data,
method: method,
pfx: pfx,
passphrase: pass,
rejectUnauthorized: false
}
urllib.request(url, options, function(err, data, res) {
if (err) {
return reject(err);
}
return resolve(data.toString());
});
});
}
request library method
const httpRequest = (url, method, data, pfx, pass) => {
return new Promise((resolve, reject) => {
let options = {
url: url,
method: method,
form: data,
headers: {
'Content-type': 'application/x-www-form-urlencoded'
},
agentOptions: {
pfx: pfx,
passphrase: pass,
rejectUnauthorized: false
}
};
request(options, function(err, httpResponse, data) {
if (err) {
return reject(err);
}
return resolve(data);
})
});
}
