示例1: encode
export function encode({ opt, data }) {
const bufList: Buffer[] = [];
let byteLen = 0;
let offset = 0;
data = Array.isArray(data) ? data : [data];
let buf = Buffer.alloc(allocLen);
bufList.push(buf);
const writeUInt = (value, byteLength) => {
byteLen += byteLength;
const less = allocLen - offset;
if (less < byteLength) {
if (less) {
// split buffer
byteLength -= less;
const i = Math.pow(2, byteLength * 8);
const l = (value / i) >>> 0;
value -= l * i;
buf.writeUIntBE(l, offset, less);
}
buf = Buffer.alloc(allocLen);
bufList.push(buf);
offset = 0;
}
buf.writeUIntBE(value, offset, byteLength);
offset += byteLength;
};
writeUInt(opt, OPT_LEN);
// set buffer
data.forEach((item) => {
const packetType = packetTypes[item.type];
writeUInt(item.type, PACKET_TYPE_LEN);

}
});
if (bufList.length > 1) {
buf = Buffer.concat(bufList, bufList.length * allocLen);
}
return buf.buffer.slice(buf.byteOffset, buf.byteOffset + byteLen);
}示例2: reject
const req = ht.get((url), (res) => {
let buffer = Buffer.alloc(0);
if (res.statusCode !== HTTP_OK) {
reject(`Non 200 status code (${res.statusCode})`);
}

};示例4: resolve
const req = ht.get( url, (res) => {
let buffer = Buffer.alloc(0);
if (res.headers.hasOwnProperty("content-type")) {
contenttype = res.headers["content-type"];
} else {
