Question

目前用户输入被保存为计算机上的文件，我想也希望它也可以上传到我的ftp服务器，我有点工作，但文件中没有任何内容，很可能因为我是编程新手，所以很容易出错，谢谢

quotation = input("Do you want to save a quotation? ")

if (quotation == "yes") :
    quotationName = input("What do you want to save the quotation as? ")

    text_file = open("{}.txt".format(quotationName),"w") #(w) opens files in write
    text_file.write ("The total lawn area is {}\n".format(totalAreaLawn))
    text_file.write ("The total for the lawn is £{}\n\n".format(totalCostLawn))
    text_file.write ("The total concrete area is {}\n".format(totalAreaConcrete))
    text_file.write ("The total for the concrete is £{}\n\n".format(totalCostConcrete))
    text_file.write ("The total wooden deck area is {}\n".format(totalAreaWoodenDeck))
    text_file.write ("The total for the wooden deck is £{}\n\n".format(totalCostWoodenDeck))
    text_file.write ("The total rectangular pond area is {}\n".format(totalAreaRectangularPond))
    text_file.write ("The total for the wooden deck is £{}\n\n".format(totalCostRectangularPond))
    text_file.write ("The total number of water features needed is {}\n".format(numberOfWaterFeatures))
    text_file.write ("The total for the water features is £{}\n\n".format(totalCostWaterFeatures))
    text_file.write ("The total number of garden lights needed is {}\n".format(numberOfGardenLights))
    text_file.write ("The total for the garden lights is £{}\n\n".format(totalCostGardenLighting))   

    #text_file.close()

    ftpconnect = ftplib.FTP('landscapegardening.freeiz.com','a6011438','L0g1tecH')

    saveDirectory = '/public_html/Quote'

    ftpconnect.cwd(saveDirectory)

    fileSend = open("{}.txt".format(quotationName),'rb')
    ftpconnect.storbinary('STOR {}.txt'.format(quotationName), fileSend)

    fileSend.close()
    ftpconnect.quit()      

    print("Quotation saved")

为什么你评论了text_file.close()行？使用这样的代码，无法保证在您要发送文件时将任何内容写入文件。我认为最好的方法是先关闭文件（只需再次在close（）行中注释），或者如果你不想重新打开同一个文件来调用text_file.flush（）后跟os.fsync(text_file)。如果您选择第二个选项，请记住将ftpconnect.storbinary('STOR {}.txt'.format(quotationName), fileSend)更改为ftpconnect.storbinary('STOR {}.txt'.format(quotationName), text_file)。您还必须将打开模式更改为“r +”并使用text_file.seek(0)转到文件的开头。

编辑：刚看到你实际上只需要一个类似文件的对象，详见这里： Can I upload an object in memory to FTP using Python?

上传FTP后，我的文本文件中没有任何内容
