我有以下代码,可以轻松连接到FTP服务器并打开一个zip文件.我想将该文件下载到本地系统.怎么做？

# Open the file for writing in binary mode
print 'Opening local file ' + filename
file = open(filename, 'wb')

# Download the file a chunk at a time
# Each chunk is sent to handleDownload
# We append the chunk to the file and then print a '.' for progress
# RETR is an FTP command

print 'Getting ' + filename
ftp.retrbinary('RETR ' + filename, handleDownload)

# Clean up time
print 'Closing file ' + filename
file.close()

我希望从亚马逊获得产品名称和描述的具体信息!爬行亚马逊是否合法.或亚马逊是否提供任何api来获取其付费或非付费数据

下面是我的表截图:

C#中的代码

SqlConnection con = new SqlConnection(connectionsession.Con);
con.Open();
SqlCommand cmd = new SqlCommand("finalinsert", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter("@fid", SqlDbType.Int)).Value = flightsession.Sflightid;
cmd.Parameters.Add(new SqlParameter("@fcid", SqlDbType.Int)).Value = flightsession.Sflightcostid;
cmd.Parameters.Add(new SqlParameter("@ftid", SqlDbType.Int)).Value = flightsession.Sflighttimingid;

我有以下数组,我想使用搜索和排序.搜索和排序就像排序我们用MySQL"LIKE"条件,但数组不在数据库中.

Array
(
    [4] => Varun Kumar
    [14] => Jason Ince
)

就像在键入'jas'时,Jason Ince的记录必须分别用键和值以及记录的其余部分来表示.
