如何用nodejs模拟get发送消息？小白提问

@hankwang 哦，我知道了~！ 谢谢~

@ggaaooppeenngg 這裡有一篇關於crypto使用的, 也可以參考一下

第一個問題:

在JavaScript你可以透過像這樣使用多行字串

var str = "abcdefghijkl\
mnopqrstuv"

** 第二個問題:**

因為你hasum.digest('hex')用了兩次。

http://nodejs.org/api/crypto.html#crypto_hash_digest_encoding

Note: hash object can not be used after digest() method has been called.

<1>好像是我的URL太长了写在了两行里面，我用sublime编辑，只有第一行被解析了所以说是非法的，我怎么把URL写在两行里面呀？

<2> 我的server用了express,大概是这样的

//app.js
app.get('/wechat',routes.token);

//index.js
exports.token = function (req, res) {
  //console.log('Token~:')
  //加密/校验流程：
  //1. 将token、timestamp、nonce三个参数进行字典序排序
  //2. 将三个参数字符串拼接成一个字符串进行sha1加密
  //3. 开发者获得加密后的字符串可与signature对比，标识该请求来源于微信
  var arr = new Array(3);
  arr[0] = '19931001'; // token
  arr[1] = req.query.nonce;
  arr[2] = req.query.timestamp;
  console.log('nonce',req.query.nonce);
  console.log('timestamp',req.query.timestamp);
  console.log('echostr',req.query.echostr);
  arr.sort();
  var shasum = crypto.createHash('sha1');
  shasum.update(arr.join(''));
  if(shasum.digest('hex') == req.query.signature)
  {
    console.log('ok');
      console.log(shasum.digest('hex'));
    console.log(req.query.echostr);
    res.send(req.query.echostr);
  }
  else
  {
    console.log(shasum.digest('hex'));
    //console.log(req.query.signature);
       res.send(req.query.signature);
  }
};

好像我的crypto没有用还是怎么了这是为什么？

虽然不是，但是也很感谢。

我整理了一下不知道是不是你想要的类似效果http://www.9958.pw/post/nodejs_get_html_a

@ggaaooppeenngg 你這樣寫是沒錯的, 你說的有點問題是出了什麼問題? 是在parse query string方面嗎?

供你參考:

client.js

var http = require('http');

http.get("http://127.0.0.1:3000/wechat?signature=d34f1983fb3ecf933b9435ad5c05b6e3a138a0e5&echostr=5898562696761927225&timestamp=137", function(res) {
  console.log("Got response: " + res.statusCode);
}).on('error', function(e) {
  console.log("Got error: " + e.message);
});

server.js

var http = require('http');
var url = require('url');
var qs = require('querystring');

http.createServer(function(req, res) {
    res.writeHead(200, {"Content-Type": "text/plain"});
    var query = url.parse(req.url).query;
    res.end(JSON.stringify(qs.parse(query)));
}).listen(3000);
