小编mg0*_*g03的帖子

我可以在我的帐户中为存储桶创建一个Amazon S3签名URL,我可以通过Amazon AWS CLI下载并上传该存储桶.

我创建了Amazon S3 URL,如下所示:

from boto.s3.connection import S3Connection
key = os.environ['aws_access_key_id']
secret = os.environ['aws_secret_access_key']
c = S3Connection(key,secret,is_secure=False)
bucket = c.get_bucket('my-bucket')
bktkey = bucket.get_key('stuff.tar.gz')
seconds=60*60*12
url2 = bktkey.generate_url(expires_in=seconds)
print '%s' %url2

url2在Chrome中使用并复制粘贴它,我下载了stuff.tar.gz.

但是当我像这样使用Wget时

wget <whatever is in url2>

我得到以下异常,

HTTP request sent, awaiting response... 403 Forbidden
2015-12-04 20:48:57 ERROR 403: Forbidden.

为什么Wget在Chrome和Firefox使用签名的Amazon S3 URL成功下载的地方失败了？

我在我的mac上编译并成功执行了二进制文件,然后将其复制到上面显示go env的ubuntu机器上.当我调用myprog二进制文件时,我得到了

bash: /usr/local/go/bin/myprog: cannot execute binary file: Exec format error

文件是

}

我想找到其数组值具有条目的键列表 svc

我可以得到以下工作

cat list.json | jq '. | map(select (. | contains(["svc"])))'

但输出是值数组而不是键本身
