this is returned/create by Open and OpenTLS functions.
Example
const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');

constructor
• new NetConn(): NetConn
Returns
NetConn
Defined in
net.ts:46
Methods
Close
▸ Close(): void
Close closes the connection.
Returns
void
Example
const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
conn.Close();
Defined in
net.ts:56
Recv
▸ Recv(N): Uint8Array
Recv is similar to RecvFull but does not guarantee full read instead
it creates a buffer of N bytes and returns whatever is returned by the connection
for reading headers or initial bytes from the server this is usually used.
for reading a fixed number of already known bytes (ex: body based on content-length) use RecvFull.
Parameters
Returns
Uint8Array
Example
const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
const data = conn.Recv(1024);
log(`Received ${data.length} bytes from the server`)
Defined in
net.ts:146
RecvFull
▸ RecvFull(N): Uint8Array
RecvFull receives data from the connection with a timeout.
If N is 0, it will read all data sent by the server with 8MB limit.
it tries to read until N bytes or timeout is reached.
Parameters
Returns
Uint8Array
Example
const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
const data = conn.RecvFull(1024);
Defined in
net.ts:128
RecvFullHex
▸ RecvFullHex(N): string
RecvFullHex receives data from the connection with a timeout
in hex format.
If N is 0,it will read all data sent by the server with 8MB limit.
until N bytes or timeout is reached.
Parameters
Returns
string
Example
const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
const data = conn.RecvFullHex(1024);
Defined in
net.ts:196
RecvFullString
▸ RecvFullString(N): string
RecvFullString receives data from the connection with a timeout
output is returned as a string.
If N is 0, it will read all data sent by the server with 8MB limit.
Parameters
Returns
string
Example
const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
const data = conn.RecvFullString(1024);
Defined in
net.ts:162
RecvHex
▸ RecvHex(N): string
RecvHex is similar to RecvFullHex but does not guarantee full read instead
it creates a buffer of N bytes and returns whatever is returned by the connection
for reading headers or initial bytes from the server this is usually used.
for reading a fixed number of already known bytes (ex: body based on content-length) use RecvFull.
Parameters
Returns
string
Example
const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
const data = conn.RecvHex(1024);
Defined in
net.ts:213
RecvString
▸ RecvString(N): string
RecvString is similar to RecvFullString but does not guarantee full read, instead
it creates a buffer of N bytes and returns whatever is returned by the connection
for reading headers or initial bytes from the server this is usually used.
for reading a fixed number of already known bytes (ex: body based on content-length) use RecvFullString.
Parameters
Returns
string
Example
const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
const data = conn.RecvString(1024);
Defined in
net.ts:179
Send
▸ Send(data): void
Send sends data to the connection with a timeout.
Parameters
Returns
void
Example
const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
conn.Send('hello');
Defined in
net.ts:112
SendArray
▸ SendArray(data): void
SendArray sends array data to connection
Parameters
Returns
void
Example
const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
conn.SendArray(['hello', 'world']);
Defined in
net.ts:84
SendHex
▸ SendHex(data): void
SendHex sends hex data to connection
Parameters
Returns
void
Example
const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
conn.SendHex('68656c6c6f');
Defined in
net.ts:98
SetTimeout
▸ SetTimeout(value): void
SetTimeout sets read/write timeout for the connection (in seconds).
Parameters
Returns
void
Example
const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
conn.SetTimeout(10);
Defined in
net.ts:70
