SSRS 下载所有历史快照

Question

是否可以一次性下载一份报表的所有历史快照？最好是 CSV 格式。与单独单击每个选项并选择“另存为 CSV”相比，可以节省大量时间。

我只看到删除

Answer 1

在 PowerShell 中，您可以循环遍历每个快照并使用以下示例保存它们：

Answer 2

在使用 powershell 时遇到问题，所以我想发布我的粗略 Python 解决方案的简化版本，灵感来自 @aduguid 答案的资源。

import requests
from requests_negotiate_sspi import HttpNegotiateAuth
import os

def downloadFile(url, file_name, download_folder, session):
    response = session.get(url, stream=True) # open the download link
    file_path = os.path.join(download_folder, file_name)
    with open(file_path, 'wb') as file: # create a new file with write binary mode
        for chunk in response.iter_content(chunk_size=1024):
            if chunk:
                file.write(chunk)

# Can also use '/Reports()' for non-linked reports.
# Can also pass in 'path="<report_path>"' instead of using id numbers,
# e.g. '.../Reports(path="/cool%20reports/my%20report")/HistorySnapshots'
api_url = r'http://<server_name>/reports/api/v2.0/LinkedReports(<item_id>)/HistorySnapshots'
session = requests.session()
session.auth = HttpNegotiateAuth() # uses windows log in
response = session.get(api_url)
hs_snapshot_list = response.json()['value']

for item_dict in hs_snapshot_list:
    download_url = (r'http://<server_name>/ReportServer/Pages/ReportViewer.aspx?<report_path>'
                    + '&rs:Snapshot=' + item_dict['HistoryId']
                    + '&rs:Format=CSV')
    downloadFile(download_url, '<your_file_name>', '<your_download_folder>', session)
