我正在尝试下载一个ZIP文件,请求将其传递给node-unzip,然后将其传输到cloudinary。
var stream = cloudinary.uploader.upload_stream(function(result) {
console.log(result)
});
request(file_url).pipe(unzip.Parse()).pipe(stream); //<-- This do not work!
ERROR: { error: { message: 'Empty file', http_code: 400 } }
fs.createReadStream('my_picture.jpg').pipe(stream); //<-- This works!
答案 0 :(得分:1)
(您没有提及,但我假设您的request
var是request的实例)
首先检查您的zip是否有效并包含您期望的内容:
(代码取自node-unzip's readme)
var unzip = require('unzip');
var request = require('request');
var fstream = require('fstream');
var writeStream = fstream.Writer('output/path');
request(file_url)
.pipe(unzip.Parse())
.pipe(writeStream);
然后,从zip中发送一个条目(即使只有一个):
var cloudinary = require('cloudinary');
var unzip = require('unzip');
var request = require('request');
var stream = cloudinary.uploader.upload_stream(function(result) {
console.log(result)
});
request(file_url)
.pipe(unzip.Parse())
.on('entry', function (entry) {
var fileName = entry.path;
var type = entry.type; // 'Directory' or 'File'
var size = entry.size;
if (fileName === "your_image.png") {
entry.pipe(stream);
} else {
entry.autodrain();
}
});
