使用带有 node-libcurl 的 FTP 时连接未正确关闭

问题描述

我正在使用 lib 在 filezilla 服务器上加载几个文件。

一切正常，文件已上传，但最后连接因超时未正确关闭。

尝试禁用被动模式，但没有任何变化。

我确定 close 被正确调用

这是 filezilla 服务器日志

这是我的上传功能（我有一个类似的功能来检查是否存在调用 close 的文件）。


const uploadFile = ({ url,username,password }) => async (
    srcPath,dstPath
) => {
let uploaded = false
    const body = await fs.readFile(srcPath,'ascii')
    const curl = new Curl()
    curl.setopt('FTP_USE_EPSV',0)
    curl.setopt('FTPPORT','-')
    curl.setopt(Curl.option.URL,ftpProt(url) + dstPath)
    curl.setopt(Curl.option.HTTPHEADER,[
        'Content-Type: application/node-libcurl.raw'
    ])
    curl.setopt('UPLOAD',1)
    curl.setopt('READFUNCTION',targetBuffer => {
        if (uploaded) {
            return 0
        }
        targetBuffer.write(body)
        uploaded = true
        return body.length
    })
    curl.setopt('USERNAME',username)
    curl.setopt('PASSWORD',password)
    const res = new Promise(function (resolve,reject) {
        curl.on('end',function (status,data) {
            this.close()
            status !== 226
                ? reject(Error(`Invalid status code: ${status}`))
                : resolve(data)
        })
        curl.on('error',function (error) {
            this.close()
            reject(error)
        })
    })
    curl.perform()
    return res
}
