错误:运行帖子时错误的标题检查 [英] Error: incorrect header check when running post
问题描述
当我运行以下程序(这是我尝试过的所有代码),但是我收到错误
事件.js:85
呃//未处理的'错误'事件
^错误:不正确的头部检查
在Zlib._handle.onerror(zlib.js:366:17)
var express = require('express'),
fs = require('fs'),
zlib = zlib'),
app = express();
app.post('/',function(req,res){
var writeStream = fs.createWriteStream('C:// myFolder',{flags:'w'}) ;
req.pipe(zlib.createInflate())。pipe(writeStream);
});
var server = app.listen(3000,function(){
console.log(Running on port+ 3000)
}
)
在邮递员标题中我添加了以下
content-Type ---->应用程序/ zip
我应该如何克服这个问题并保存zip? 还有其他推荐(zlib)库来提取和保存zip?
zlib
旨在提取gzip压缩或放空的数据,而不是.ZIP文件。
您可以使用 node-unzip
模块:
var unzip = require('unzip');
...
app.post('/',function(req,res){
var extractor = unzip.Extract({path:'C:// myFolder'}) on('close',function(){
res.sendStatus(200);
})。on('error',function(err){
res.sendStatus(500);
});
req.pipe(extractor);
});
如果Postman无法处理这样的上传(如评论中所建议的),您可以使用cURL:
$ curl -XPOST localhost:3000 --data-binary @ test.zip
I need to get zip from rest call (for simulation I use postman with binary option for post and add a little zip file with folder and html file),during the simulation I want to get the data with express and extract the zip and put in some folder under C drive. Currently when I run the following program(this is all the code which i've tried) but im getting error
events.js:85 throw er; // Unhandled 'error' event ^ Error: incorrect header check at Zlib._handle.onerror (zlib.js:366:17)
var express = require('express'),
fs = require('fs'),
zlib = require('zlib'),
app = express();
app.post('/', function (req, res) {
var writeStream = fs.createWriteStream('C://myFolder', {flags: 'w'});
req.pipe(zlib.createInflate()).pipe(writeStream);
});
var server = app.listen(3000, function () {
console.log("Running on port" + 3000)
}
)
in postman header i've added the following
content-Type ----> application/zip
How should I overcome this issue and save the zip ? there is other recommended (zlib)library to get extract and save zip?
zlib
is meant to extract gzipped or deflated data, not .ZIP files.
You can use the node-unzip
module for those:
var unzip = require('unzip');
...
app.post('/', function(req, res) {
var extractor = unzip.Extract({ path : 'C://myFolder' }).on('close', function() {
res.sendStatus(200);
}).on('error', function(err) {
res.sendStatus(500);
});
req.pipe(extractor);
});
If Postman can't handle uploads like this (as suggested in the comments), you can test using cURL:
$ curl -XPOST localhost:3000 --data-binary @test.zip
