Question

我有这样的网址：

https://www.oslobors.no/ob/servlets/excel?type=history&columns=TIME%2C+BUYER%2C+SELLER%2C+PRICE%2C+VOLUME%2C+TYPE&format[TIME]=dd.mm.YY%20hh:MM:ss&format[PRICE]=%23%2C%23%230.00%23%23%23&format[VOLUME]=%23%2C%23%230&header[TIME]=Statoil&header[BUYER]=Kj%C3%B8per&header[SELLER]=Selger&header[PRICE]=Pris&header[VOLUME]=Volum&header[TYPE]=Type&view=DELAYED&source=feed.ose.trades.INSTRUMENTS&filter=ITEM_SECTOR%3D%3DsSTL.OSE%26%26DELETED!%3Dn1&stop=now&start=1493935200000&ascending=true

我可以在Excel中打开它（删除＆＃39; l＆＃39; in＆＃39; tinyurll＆＃39;）：

Sub Get_File()
    Dim oXMLHTTP As Object: Set oXMLHTTP = CreateObject("MSXML2.ServerXMLHTTP")
    Dim strURL As String: strURL = "http://tinyurll.com/api-create.php?url=https://www.oslobors.no/ob/servlets/excel?type=history&columns=TIME%2C+BUYER%2C+SELLER%2C+PRICE%2C+VOLUME%2C+TYPE&format[TIME]=dd.mm.YY%20hh:MM:ss&format[PRICE]=%23%2C%23%230.00%23%23%23&format[VOLUME]=%23%2C%23%230&header[TIME]=Statoil&header[BUYER]=Kj%C3%B8per&header[SELLER]=Selger&header[PRICE]=Pris&header[VOLUME]=Volum&header[TYPE]=Type&view=DELAYED&source=feed.ose.trades.INSTRUMENTS&filter=ITEM_SECTOR%3D%3DsSTL.OSE%26%26DELETED!%3Dn1&stop=now&start=1493935200000&ascending=true"
        With oXMLHTTP: .Open "GET", strURL, False: .send: End With

        strURL = oXMLHTTP.responseText

        With Workbooks: .Open strURL, IgnoreReadOnlyRecommended:=True: End With
End Sub

但我想将内容下载到文本文件中，而不是使用Python下载excel文件？

Answer 1

即使该文件将作为excel文件（可能是.xlsx）下载，我认为您仍然可以打开并将其作为带有Python的CSV文件读取（可能需要查看this question获得更多细节如何）。如果这个excel文件有多个工作表，那么最终可能会出现问题。如果是这种情况，您可能需要使用额外的库（like pandas）来管理打开并从excel文件中捕获数据。

打开并读取文件后，您可以只使用要保留的内容写入新的文本文件。 This other question有一些关于如何做到这一点的好信息。

如果文件中只有一个工作表，那么csv方法就可以了，看起来像这样：

（已修改，将rb更改为rt并打开CSV

import csv

my_read_path = '/directory/some_excel_file.xlsx'
text_file = open('/directory/my_output.txt', "w")
with open(my_read_path, 'rt') as csv_file:
    csv_reader = csv.reader(csv_file)
    for line in list(csv_reader):
        text_file.write(line)  # assumes you want to write any line

text_file.close()

用pandas之类的东西读书可能会更复杂，但无论如何都可能是一次宝贵的学习经历。

Answer 2

我设法下载到＆＃39; .xlsx＆＃39;文件使用：

import requests
import time
import csv

url = 'https://www.oslobors.no/ob/servlets/excel?type=history&columns=TIME%2C+BUYER%2C+SELLER%2C+PRICE%2C+VOLUME%2C+TYPE&format[TIME]=dd.mm.YY%20hh:MM:ss&format[PRICE]=%23%2C%23%230.00%23%23%23&format[VOLUME]=%23%2C%23%230&header[TIME]=Statoil&header[BUYER]=Kj%C3%B8per&header[SELLER]=Selger&header[PRICE]=Pris&header[VOLUME]=Volum&header[TYPE]=Type&view=DELAYED&source=feed.ose.trades.INSTRUMENTS&filter=ITEM_SECTOR%3D%3DsSTL.OSE%26%26DELETED!%3Dn1&stop=now&start=1493935200000&ascending=true'
file_name = 'C:\\Users\\AR\\Documents\\DownloadFile.xlsx'

while True:
    try:
        resp = requests.get(url)
        with open(file_name, 'wb') as output:
            output.write(resp.content)
            break
    except Exception as e:
        print(str(e))
        time.sleep(3)

使用扩展程序＆＃39; .txt＆＃39;在＆＃39; file_name＆＃39;中，给我一个以：

开头的文件

Answer 3

使用＆＃39; Openpyxl＆＃39;找到解决方案（即可以从excel文件中读取而无需打开Excel（excel工作簿）：

from openpyxl import load_workbook #https://openpyxl.readthedocs.io/en/latest/index.html
import requests
import time

url = 'https://www.oslobors.no/ob/servlets/excel?type=history&columns=TIME%2C+BUYER%2C+SELLER%2C+PRICE%2C+VOLUME%2C+TYPE&format[TIME]=dd.mm.YY%20hh:MM:ss&format[PRICE]=%23%2C%23%230.00%23%23%23&format[VOLUME]=%23%2C%23%230&header[TIME]=Statoil&header[BUYER]=Kj%C3%B8per&header[SELLER]=Selger&header[PRICE]=Pris&header[VOLUME]=Volum&header[TYPE]=Type&view=DELAYED&source=feed.ose.trades.INSTRUMENTS&filter=ITEM_SECTOR%3D%3DsSTL.OSE%26%26DELETED!%3Dn1&stop=now&start=1493935200000&ascending=true'
file_name = 'DownloadFile.xlsx'

while True:
    try:
        resp = requests.get(url)
        with open(file_name, 'wb') as output:
            output.write(resp.content)
            break
    except Exception as e:
        print(str(e))
        time.sleep(3)

wb = load_workbook(file_name)
ws = wb['data']
for row in ws.rows:
    for cell in row:
        print(cell.value)

Answer 4

这是一个可行的解决方案，可以下载文件，保存到excel文件，从excel文件读取并保存为可读文本到文本文件。

from openpyxl import load_workbook #https://openpyxl.readthedocs.io/en/latest/index.html
import requests
import time

url = 'https://www.oslobors.no/ob/servlets/excel?type=history&columns=TIME%2C+BUYER%2C+SELLER%2C+PRICE%2C+VOLUME%2C+TYPE&format[TIME]=dd.mm.YY%20hh:MM:ss&format[PRICE]=%23%2C%23%230.00%23%23%23&format[VOLUME]=%23%2C%23%230&header[TIME]=Statoil&header[BUYER]=Kj%C3%B8per&header[SELLER]=Selger&header[PRICE]=Pris&header[VOLUME]=Volum&header[TYPE]=Type&view=DELAYED&source=feed.ose.trades.INSTRUMENTS&filter=ITEM_SECTOR%3D%3DsSTL.OSE%26%26DELETED!%3Dn1&stop=now&start=1493935200000&ascending=true'
file_name = 'DownloadFile.xlsx'
sdv_file_name = 'DownloadFile.sdv'

while True:
    try:
        resp = requests.get(url)
        with open(file_name, 'wb') as output:
            output.write(resp.content)
            break
    except Exception as e:
        print(str(e))
        time.sleep(3)

wb = load_workbook(filename=file_name, read_only=True)
ws = wb['data']
ws.max_row = ws.max_column = None
with open(sdv_file_name, 'a') as output:
    for row in ws.rows:
        line = str(row[0].value)+';'+str(row[1].value)+';'+str(row[2].value)+';'+str(row[3].value)+';'+str(row[4].value)+';'+str(row[5].value)+'\n'
        output.write(line)

下载＆＃39; servlets＆＃39;到文本文件而不是excel
