Whant I need is to get a zip file from request(Im using express and I've request and response) and I need to extract(unzip) it to some path(in the example for my local drive) ,where should I put the req and what Im missing here to make it work 我需要的是从请求获取一个zip文件（我使用快递和我的请求和响应）我需要提取（解压缩）它到某个路径（在本地驱动器的示例中），我应该在哪里放req和我在这里失踪的东西让它发挥作用
fn: function (req, res) {
var admZip = require('adm-zip');
var zip = new admZip();
zip.addLocalFile("C://TestFolder//TestZip");
in the request body im getting the zip file(im using postman and in the body I use the binary and select a zip file) 在请求正文中我获取zip文件（即时通讯使用邮递员，在我体内使用二进制文件并选择一个zip文件）

You could simplify the problem by using form-data instead of binary and using multer . 您可以使用form-data而不是binary和使用multer来简化问题。 You can get the input file by accessing req.file after which you can perform your unzip operation. 您可以通过访问req.file来获取输入文件，之后您可以执行解压缩操作。
For example, you would add to your route: 例如，您将添加到您的路线：
var upload = require('multer')({ dest: 'uploads/' });
var admZip = require('adm-zip');
app.post('/upload-here', upload.single('file'), function (req, res, next) {
var zip = new admZip(req.file.path);
zip.extractAllTo("C://TestFolder//TestZip", true);
});

Please try my snippet code : 请尝试我的代码段：
For some information, My App structure like this below : 有关一些信息，我的App结构如下：
my path --> C:\xampp\htdocs\service
service
|
-- tmp\
|
-- app.js
|
-- index.html
Client Side: 客户端：
<html>
<body>
<h3>ZIP Upload:</h3>
<form action="/upload_zip" method="POST" enctype="multipart/form-data">
Select zip to upload:
<input type="file" name="zipFile" id="zipFile">
<input type="submit" value="Upload ZIP" name="submit">
</form>
</body>
</html>
Server Side: 服务器端：
Don't forget using enctype="multipart/form-data" when you post it using postman or something like that... 当你使用邮递员或类似的东西发布它时，不要忘记使用enctype="multipart/form-data" ...
var express = require("express");
var fs = require("fs");
var AdmZip = require('adm-zip');
var app = express();
var multer = require("multer");
var multer_dest = multer({dest: "./tmp"}).single('zipFile');
app.get("/",function(req,res){
console.log("Show index.html");
res.sendFile(__dirname+"/"+"index.html");
});
app.post("/upload_zip",multer_dest,function(req,res){
console.log(req.file);
var zip = new AdmZip(req.file.path);
zip.extractAllTo("./tmp");
result = {
file:req.file,
message:"File has been extracted"
};
fs.unlink(req.file.path, function (e) {
if (e) throw e;
console.log('successfully deleted '+req.file.path);
});
res.end(JSON.stringify(result));
});
var server = app.listen(8081,function(){
var host = server.address().address;
var port = server.address().port;
console.log("Example App Listening at http://%s:%s",host,port);
})
