Question

我正在尝试使用节点内置模块zlib从压缩数据中解压缩文件，由于某种原因，我无法解压缩它，出现如下错误：

Error: incorrect header check
test.js:53
No debug adapter, can not send 'variables'

我正在尝试的代码如下：

var zlib = require('zlib');
var fs = require('fs');
var filename = './Divvy_Trips_2019_Q2.zip';

var str1 = fs.createReadStream(filename);

var gzip = zlib.createGunzip();

str1.pipe(gzip).on('data', function (data) {
    console.log(data.toString());
}).on('error', function (err) {
    console.log(err);
});

压缩数据的URL如下：Divvy_Trips_2019_Q2.zip

GZip（.gz）和ZIP（.zip）是不同的格式。您需要一个处理ZIP文件的库，例如yauzl。

// https://github.com/thejoshwolfe/yauzl/blob/master/examples/dump.js

const yauzl = require("yauzl");

const path = "./Divvy_Trips_2019_Q2.zip";

yauzl.open(path, function(err, zipfile) {
  if (err) throw err;
  zipfile.on("error", function(err) {
    throw err;
  });
  zipfile.on("entry", function(entry) {
    console.log(entry);
    console.log(entry.getLastModDate());
    if (/\/$/.exec(entry)) return;
    zipfile.openReadStream(entry, function(err, readStream) {
      if (err) throw err;
      readStream.pipe(process.stdout);
    });
  });
});

无法使用zlib模块解压缩压缩文件
