所以我将此代码改编自here用于学习目的:
"use strict";
/// <reference path="./definitelyTyped/node/node.d.ts" />
import * as net from "net";
let sockets: net.Socket[] = [];
/*
* Cleans the input of carriage return, newline
*/
function cleanInput(data: Buffer): string {
return data.toString().replace(/(\r\n|\n|\r)/gm, "");
}
/*
* Method executed when data is received from a socket
*/
function receiveData(socket: net.Socket, data: Buffer): void {
let cleanData: string = cleanInput(data);
if (cleanData === "@quit") {
socket.end("Goodbye!\r\n");
} else {
for (var i: number = 0; i < sockets.length; i++) {
if (sockets[i] !== socket) {
sockets[i].write(data);
}
}
}
}
/*
* Method executed when a socket ends
*/
function closeSocket(socket: net.Socket): void {
let i: number = sockets.indexOf(socket);
if (i !== -1) {
sockets.splice(i, 1);
}
}
/*
* Callback method executed when a new TCP socket is opened.
*/
function newSocket(socket: net.Socket): void {
sockets.push(socket);
socket.write("Welcome to the Telnet server!\r\n");
socket.on("data", function(data: Buffer): void {
receiveData(socket, data);
});
socket.on("end", function(): void {
closeSocket(socket);
});
}
// create a new server and provide a callback for when a connection occurs
let server: net.Server = net.createServer(newSocket);
// listen on port 4444
server.listen(4444);
console.log("started");
我使用这些tslint规则在此文件上运行tslint.json。
这就是我得到的:
app.ts [10,1]:缺少&#39;使用严格的&#39;
app.ts [17,1]:缺少&#39;使用严格的&#39;
app.ts [33,1]:缺少&#39;使用严格的&#39;
app.ts [43,1]:缺少&#39;使用严格的&#39;
我的理解是,文件第一行的"use string";
应该是整个文件的全局。然而,每个函数都会产生一个消息。我错过了什么吗?

您的理解是正确的。但是,您请求tslint以确保所有函数以及"check-function"
set to true。将其设置为false,因为如果您已启用模块级别,则不需要它。

可以在全局范围或单个函数中启用严格模式:
// Enable strict mode globally
"use strict";
var v = "This script is in strict mode.";
或在当地:
function strict() {
'use strict';
function nested() {
return "Nested function is also in strict mode.";
}
return "Function is in strict mode. " + nested();
}
function notStrict() {
return "This function is not in strict mode.";
}
