我尝试使用NodeJS将目录中的所有文件上传到我的S3存储桶。如果我明确地为Key:
字段提供文件路径+文字字符串,我一次能够上传一个文件。
以下是我使用的脚本:
var AWS = require('aws-sdk'),
fs = require('fs');
// For dev purposes only
AWS.config.update({ accessKeyId: '...', secretAccessKey: '...' });
// reg ex to match
var re = /\.txt$/;
// ensure that this file is in the directory of the files you want to run the cronjob on
// ensure that this file is in the directory of the files you want to run the cronjob on
fs.readdir(".", function(err, files) {
if (err) {
console.log( "Could not list the directory.", err)
process.exit( 1 )
}
var matches = files.filter( function(text) { return re.test(text) } )
console.log("These are the files you have", matches)
var numFiles = matches.length
if ( numFiles ) {
// Read in the file, convert it to base64, store to S3
for( i = 0; i < numFiles; i++ ) {
var fileName = matches[i]
fs.readFile(fileName, function (err, data) {
if (err) { throw err }
// Buffer Pattern; how to handle buffers; straw, intake/outtake analogy
var base64data = new Buffer(data, 'binary');
var s3 = new AWS.S3()
s3.putObject({
'Bucket': 'noonebetterhaventakenthisbucketnname',
'Key': fileName,
'Body': base64data,
'ACL': 'public-read'
}, function (resp) {
console.log(arguments);
console.log('Successfully uploaded, ', fileName)
})
})
}
}
})
它会为尝试上传到S3的每个文件产生此错误:
These are the files you have [ 'test.txt', 'test2.txt' ]
{ '0': null,
'1': { ETag: '"2cad20c19a8eb9bb11a9f76527aec9bc"' } }
Successfully uploaded, test2.txt
{ '0': null,
'1': { ETag: '"2cad20c19a8eb9bb11a9f76527aec9bc"' } }
Successfully uploaded, test2.txt
修改:使用变量名更新以允许读取密钥而不是matches[i]
为什么只上传test2.txt
,如何上传matches
变量中的每个文件?
答案 0 :(得分:7)
参考此Asynchronously reading and caching multiple files in nodejs以获得解决方案。
tl; dr 范围问题 - 需要在变量中包装变量;可以通过为<article>
<div class="h">
<div class="pb">user</div>
<div class="pb">date <a id="m75813" href="#m75183">#</a></div>
</div>
<div class="text" onclick="alert(parentNode.parentElement.firstChild.childNodes[1].a.id);">
After clicking on the yellow background, the value from [a id="m75813"] (ie. 'm75813') should apppear. Sentence text.<br> Other sample.<br> Hello world.
</div>
</article>
和readFile
创建一个函数并在for循环中调用它来完成此操作。
s3.putObject
