我有一个这个地址的文件:
http://s3.amazonaws.com/bucket-name/sdile_pr_2_1_1/pr/0/2/1/1/dile_0_2_1_1.nc
在s3桶中,我希望通过烧瓶应用程序访问。
这样做我创建了一个如下所示的函数:
@app.route('/select/dile')
def select_dile_by_uri():
uri=request.args.get('uri')
if uri is not None:
if uri.startswith("http://s3.amazonaws.com/"):
path = uri.replace("http://s3.amazonaws.com/","")
bname, kstr = path.split("/",1) # split the bname from the key string
conn = S3Connection(AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY)
try:
bucket = conn.get_bucket(bname)
except:
print "BUCKET NOT FOUND"
return str("ERROR: bucket "+bname+" not found")
else:
print "BUCKET CONNECTED"
try:
key = bucket.get_key(kstr)
print "KEY: ", key
except:
print "KEY NOT FOUND"
return str("ERROR: key "+kstr+"not found")
else:
try:
key.open_read() # opens the file
headers = dict(key.resp.getheaders()) # request the headers
return Response(key, headers=headers) # return a response
except S3ResponseError as e:
return Response(e.body, status=e.status, headers=key.resp.getheaders())
abort(400)
下载有效,但下载文件的名称似乎只是" dile"而不是dile_0_2_1_1.nc。
为什么?有什么我需要设置的吗?
答案 0 :(得分:0)
我需要做的是在标题中添加一个字段,特别是:
headers["Content-Disposition"] = "inline; filename=myfilename"
其中-myfilename-是您希望文件具有的名称。
