Node.js 读本地文件和发起 POST 网络请求

最近需要使用 Nodejs 读取本地文件中的数据构造请求去批量请求 CGI 获取数据，这样就不用手工搬砖了。因为需要携带 Cookie，故使用 POST 方法。

代码

1// 读取本地文件
2var fs = require("fs");
3var readline = require('readline');
4
5var rd = readline.createInterface({
6    input: fs.createReadStream('./test.md'),
7    output: process.stdout,
8    terminal: false
9});
10
11var http = require("http");
12var url = require("url");
13var cookie = "K1:v1"
14
15rd.on('line', function(line) {
16    var parts = line.split(',')
17    keyword = parts[0]
18    newIndex = parts[1]
19    strUrl = "http://wwwtest.com" + keyword + "&start_time=1485241176.43&end_time=1492930776.43&version=0"
20
21    var parse = url.parse(strUrl);
22    // 待发送的数据
23    var postStr = "test";
24    var options = {
25        "method": "POST",
26        "host": parse.hostname,
27        "path": parse.path,
28        "port": parse.port,
29        "headers": {
30            "Content-Length": postStr.length,
31            'Cookie': cookie
32        }
33    };
34
35    var req = http.request(options, function(res) {
36    	word = parts[0]
37    	new_index = parts[1]
38        res.setEncoding("utf-8");
39        var resData = [];
40        res.on("data", function(chunk) {
41            resData.push(chunk);
42        }).on("end", function() {
43            console.log(resData.join(""));
44        });
45    });
46    req.write(postStr);
47    req.end();
48});
