Question

我使用以下python代码生成了一个Soundcloud轨道ID列表：

import soundcloud
import urllib

client = soundcloud.Client(client_id='XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
                       client_secret='XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
                       username='XXXXXXXXXXXXXXXXXXXXXXXXXX',
                       password='XXXXXXXXXXXXXXXXXX')

f=open('soundcloud-track-ids', 'w+')

count = 0
while count < 6000:
    tracks = client.get('/me/tracks', limit=200, offset=count)
    for track in tracks:
        print >>f, track.id, "\t", track.title .encode('utf-8')
    count += 200

f.close()

然后我运行了一个bash脚本来将整个存档备份到硬盘驱动器的内容：

#!/bin/bash

SAVEIFS=$IFS
IFS=$(echo -en "\n\b")

while read line; do
    if [ ! -f /mnt/drobo_1/Soundcloud/$(echo $line | cut -f 2- | sed 's,/,\ ,g').mp3 ];     then
        wget https://api.soundcloud.com/tracks/"$(echo $line | awk '{print $1}')"/download?oauth_token=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX \
        -O /mnt/drobo_1/Soundcloud/"$(echo $line | cut -f 2- | sed 's,/,\ ,g').mp3"
    fi
done < ./soundcloud-track-ids

IFS=$SAVEIFS

几乎所有的5317首曲目都是私密的，而且大多数都是没有问题的下载，但是大约有600首曲目无法下载，并出现以下错误：

有谁知道错误是什么？

Answer 1

404错误表示在SoundCloud结束时无法找到该文件。它可能是SoundCloud的速率限制器，可以防止你如此抨击它。

请参阅https://developers.soundcloud.com/docs/api/terms-of-use#quotas

如果您稍后尝试下载失败，那么它们有效吗？
