我编写了以下简单程序进行测试:
s3 = boto3.client('s3')
s3r = boto3.resource('s3')
Bucket=s3r.Bucket('bucketname')
for obj in Bucket.objects.filter(Prefix='<timestamp>/'): # add prefix only if you want objects of a particular subfolder
filename=obj.key
key=str(filename)
local="C://path_to_save-file"
s3.download_file('bucketname',key, local)
#your code goes here to use downloaded file
对于每个this page,我从HelloZip项目目录运行using System;
using System.IO;
using System.IO.Compression;
namespace HelloZip
{
class Program
{
static void Main(string[] args)
{
string path = Path.Combine(AppContext.BaseDirectory, "test.zip");
using (ZipArchive z = ZipFile.Open(path, ZipArchiveMode.Create))
{
var f = z.CreateEntry("hello.txt");
using (StreamWriter writer = new StreamWriter(f.Open()))
{
writer.Write("Hello World!");
}
}
}
}
}
,在nuget.config中添加了推荐的软件包源,然后运行了以下命令:
dotnet new nuget
我遇到以下错误:
dotnet add package Microsoft.DotNet.ILCompiler -v 1.0.0-alpha-*
dotnet publish -r win-x64 -c release -o out
out\HelloZip.exe
我犯错了吗,还是AOT编译器还不能正确支持System.IO.Compression?
答案 0 :(得分:1)
您正在使用已知的未实现功能。解决方法是暂时将clrcompression.dll手动复制到已编译的可执行文件旁边。在此处查看详细信息:https://github.com/dotnet/corert/issues/5496
