我正在尝试使用nodejs和tern打印自动完成js文件.Ternjs拥有我见过的最糟糕的文档.

var tern = require("tern")

var ternServer = new tern.Server({})

var requestDetails = {
        "query": {
            "type": "completions",
            "file": "myfile.js",
            "end": {"line":0,"ch":3},
            "types":true,
            "includeKeywords":true,
            "sort":true,
            "guess":true,
            "docs":true,
            "urls":true,
            "origins":true,
            "lineCharPositions":true,
            "caseInsensitive":true
        },
        "files": [
            {
                "type": "full",
                "name": "myfile.js",
                "text": 'req'
            }
        ]
}

ternServer.request(requestDetails, function(error, success){
    console.log(success);
});

它不工作,但如果我使用con它提供继续和const.但不是在那之后.在原子插件中,它提供了模块自动完成功能.我错过了什么.

这也是.tern-project文件

{
  "ecmaVersion": 6,
  "libs": [
    "browser",
    "jquery",
    "requirejs",
    "commonjs"
  ],
  "plugins": {
    "complete_strings": {
      "maxLength": 15
    },
    "node": {},
    "lint": {},
    "doc_comment": {
      "fullDocs": true,
      "strong": true
    }
  } …

我一直试图将代码放在一起,以实际保存指纹传感器的图像.我已经尝试了论坛,这是我当前的代码,它保存文件的文件大小正确,但当我打开图像时,它不是指纹图像,而是看起来像一个损坏的图像.这是它的样子.

我的代码如下.任何帮助将不胜感激.我是Windows开发的新手.

bool SaveBMP(BYTE* Buffer, int width, int height, long paddedsize, LPCTSTR bmpfile)
    {
        BITMAPFILEHEADER bmfh;
        BITMAPINFOHEADER info;
        memset(&bmfh, 0, sizeof(BITMAPFILEHEADER));
        memset(&info, 0, sizeof(BITMAPINFOHEADER));
        //Next we fill the file header with data:
        bmfh.bfType = 0x4d42;       // 0x4d42 = 'BM'
        bmfh.bfReserved1 = 0;
        bmfh.bfReserved2 = 0;
        bmfh.bfSize = sizeof(BITMAPFILEHEADER) +
            sizeof(BITMAPINFOHEADER) + paddedsize;
        bmfh.bfOffBits = 0x36;
        //and the info header:
        info.biSize = sizeof(BITMAPINFOHEADER);
        info.biWidth = width;
        info.biHeight = height;
        info.biPlanes = 1;

        info.biBitCount = 8;
        info.biCompression = BI_RGB;

        info.biSizeImage = 0; …

我需要能够在应用程序级别上平衡websocket.让我们说基于我收到的消息转发websocket请求,在代理上解码然后使用某些逻辑将该数据发送到另一个套接字服务器.

但我无法做到这一点.这是我编写的初始代码并尝试这样做.这是服务器

var http = require('http');
var httpProxy = require('http-proxy');
var WebSocket = require('ws');

var WebSocketServer = require('ws').Server;
var wss = new WebSocketServer({ port: 8080 });

wss.on('connection', function connection(ws) {
    ws.on('message', function incoming(message) {
        console.log('received: %s', message);
    });
    ws.send('something');
});

var proxy = httpProxy.createServer({target: 'ws://localhost:8080', ws:true});


var server = httpProxy.createServer(function(req, res) {
    //SOME LOGIC HERE TO PARSE WS DATA AND SEND TO WS SERVER
    proxy.ws(req, res, { target: 'ws://localhost:8080'});
}).listen(8014);

客户

var http = require('http');
var httpProxy = require('http-proxy');
var …

我正在尝试这个构造函数代码,并对它的工作方式感到困惑.

#include<iostream>
using namespace std;
class XYZ{
    int a,b;
    public:
        XYZ(int i, int j):a(i), b(a*j){}
        void show(){
            cout<<a<<"\t"<<b<<"\n";
        }
};
int main(){
    XYZ X(2,3);
    X.show();
    return 0;
}

它给出了预期的结果,但是,

#include<iostream>
using namespace std;
class XYZ{
    int b,a;
    public:
        XYZ(int i, int j):a(i), b(a*j){}
        void show(){
            cout<<a<<"\t"<<b<<"\n";
        }
};
int main(){
    XYZ X(2,3);
    X.show();
    return 0;
}

出乎意料的结果.

唯一的区别是int a,b和int b,a

以及如何XYZ(int i, int j):a(i), b(a*j){}正常工作？
