Question

所有我尝试使用ftplib（jenkins作业）将文件从远程服务器复制到另一台服务器时遇到以下错误。在我的本地系统中，它运行正常

1）还提到了python代码，有人可以让我知道如何解决这个问题吗？
2）如果有人可以指导如何提及服务器，用户名和密码而无需在脚本中进行硬编码，这也将非常有帮助。

错误：

12:33:00 [EnvInject] - Loading node environment variables.

下面是python代码，

from psycopg2 import connect, sql 
from time import perf_counter
import psycopg2
import time
import os
from ftplib import FTP


start_time = time.perf_counter()

cnx_psql = psycopg2.connect(host="localhost", database="postgres", user="postgres",
                        password="postgres", port="5432")

# Cursors initializations
cur_psql = cnx_psql.cursor()

def getFile(ftp, filename):
    try:
        local_filename = os.path.join(r"/Users/sand/Downloads/", filename)
        #local_filename = os.path.join(r"/home/etl/bi/csv_imports/", filename)
        lf = open(local_filename, "wb")
        ftp.retrbinary("RETR " + filename ,lf.write)
        print("file copied")
    except (Exception, psycopg2.Error) as error:
        print ("Error: {}".format(error))
try:

    filePath='''/Users/sand/Downloads/log'''
    table='staging.stock_dump'

    SQL="""DROP TABLE IF EXISTS """+  table + """;CREATE TABLE """+ table + """
    (created_date TEXT, product_sku TEXT, previous_stock TEXT, current_stock TEXT );"""

    #keys = ['created_date', 'product_sku', 'previous_stock', 'current_stock']
    #sql.SQL("""CREATE TABLE IF NOT EXISTS {} ({});""").format(sql.Identifier(table),sql.SQL(' TEXT,').join(map(sql.Identifier, keys))))
    cur_psql.execute(SQL)
    cnx_psql.commit()

    try:
     ftp = FTP('server.com','username','password')
     print("FTP connection succesful")
     ftp.cwd('/stockitem/')
    except (Exception, psycopg2.Error) as error:
     print ("Error: {}".format(error))
    getFile(ftp,'log')

    read_file = open(filePath, "r")
    my_file_data = read_file.readlines()

    for line in my_file_data:
        if 'Stock:' in line:
            fields=line.split(" ")
            date_part1=fields[0]
            date_part2=fields[1][:-1]
            sku=fields[3]
            prev_stock=fields[5]
            current_stock=fields[7]
            if prev_stock.strip()==current_stock.strip():
                continue
            else:
               cur_psql.execute("insert into " + table+"(created_date, product_sku, previous_stock , current_stock)" + " select CAST('" + date_part1+ " "+ date_part2 + "' AS TEXT)" +", CAST('"+sku+"' AS TEXT),CAST('" + prev_stock +"' AS TEXT),CAST('" +current_stock  + "' AS TEXT);")
    cnx_psql.commit()       
    cur_psql.close()
    cnx_psql.close()
    print("Data loaded to DWH from text file")
    print("Data porting took %s seconds to finish---" % (time.perf_counter() - start_time))          
except (Exception, psycopg2.Error) as error:
        print ("Error: {}".format(error))
        print("Error adding  information.")
        quit()
finally:
    ftp.close()

使用Python ftplib将文件从远程服务器复制到另一个服务器时，权限被拒绝错误
