如何将从Scrapy到FTP的爬网数据存储为csv？

My scrapy settings.py

from datetime import datetime
file_name = datetime.today().strftime('%Y-%m-%d_%H%M_')
save_name = file_name + 'Mobile_Nshopping'
FEED_URI = 'ftp://myusername:mypassword@ftp.mymail.com/uploads/%(save_name)s.csv'

当我运行我的蜘蛛抓取我的\u项目\u名称时出现错误。。。 我可以创建一个管道吗

我不知道如何将CSV存储到FTP中。 因为我的密码是int，所以出现错误？ 有什么我忘了写的吗

我可以创建一个管道吗

是的，您可能应该创建一个管道。如中所示，基本概念是：发送请求，响应返回并由爬行器处理，最后，管道对爬行器返回的项目进行处理。在您的情况下，您可以创建一个管道，将数据保存在CSV文件中，并将其上载到ftp服务器。有关更多信息，请参阅

我不知道如何将CSV存储到FTP中。因为我的密码是int，所以会出现错误？有什么我忘记写的吗

我认为这是由于下面的弃用错误（显示在您提供的错误顶部）：

scrapydeproductionwarning:FEED\u URI和FEED\u格式设置已被弃用，取而代之的是FEED设置。有关详细信息，请参阅FEED设置文档

---

尝试将

FEED\u URI

替换为

FEED

；请参阅。

您还需要指定端口

可以在“设置”中指定此选项

另请参见scrapy文档中的类定义

类FTPFilesStore:

FTP_USERNAME = None
FTP_PASSWORD = None
USE_ACTIVE_MODE = None

def __init__(self, uri):
    if not uri.startswith("ftp://"):
        raise ValueError(f"Incorrect URI scheme in {uri}, expected 'ftp'")
    u = urlparse(uri)
    self.port = u.port
    self.host = u.hostname
    self.port = int(u.port or 21)
    self.username = u.username or self.FTP_USERNAME
    self.password = u.password or self.FTP_PASSWORD
    self.basedir = u.path.rstrip('/')
