我目前很难使用 xml rpc 从 Odoo 13 下载 PDF 格式的发票。
我能得到的最接近的是：
model_name = 'ir.actions.report'
model_method = 'render_qweb_pdf'
report_id = 282
invoice_id = 4
args = [[report_id]]
kwargs = {'res_ids': [invoice_id]}
models = ServerProxy('{}/xmlrpc/2/object'.format(url))
return models.execute_kw(db, uid, password,
model_name, method_name,
args, kwargs)
但我总是遇到这个错误：
...py", line 46, in execute_kw
args, kwargs)
File "/usr/lib/python3.6/xmlrpc/client.py", line 1112, in __call__
return self.__send(self.__name, args)

它试图在这

所以它实际上看起来相当不错，很有前途......:(
Odoo 13 现在有更好的方法吗？我检查了一下，Odoo 12 等的所有信息似乎都已过时，因为模型/报告/函数/xrpc 调用...全部都不存在了...
发现 jsonrpc 后，我终于能够下载发票了...希望这对没有 xmlrpc 解决方案的人有所帮助。 （我仍在寻找 xml rpc 解决方案。）

谢谢您的回答！
我找到了以下适用于 XML RPC 的解决方案：
Odoo 16 中的代码：
class InvoiceXMLRPC(models.Model):
_inherit = "ir.actions.report"
def render_qweb_pdf_inherit(self, report_ref, res_ids=None, data=None):
pdf_content = self._render_qweb_pdf(report_ref, res_ids=res_ids, data=data)
pdf_content_encoded = base64.b64encode(pdf_content[0]) # needs to be encoded to be able to access with xmlrpc
return pdf_content_encoded
Raspberry Pi 上的代码：
result = models.execute_kw(db, uid, password,
'ir.actions.report', 'render_qweb_pdf_inherit',[REPORT_ID, REPORT_ID],{'res_ids': invoice_ids})
invoice_content = base64.b64decode(result)
with open('/home/pi/InvoicePrintO16/invoices.pdf', 'wb') as report_file:
report_file.write(invoice_content)
os.system('lp invoices.pdf')
感谢您的回复。我还尝试使用外部 API 从 Odoo 16 获取 PDF 报告。在

我在 Odoo 17 中尝试过此操作。发布此答案以便有人可以获得帮助。 下面是代码。

# Replace these with your own Odoo connection details
url = 'https://your_odoo_instance_url.com'

'method': 'call',
'params': {
"service": "common",
"method": "login",
'db': db,
'login': username,
'password': password,
}
}
session_response = requests.post(session_url, json=data)
session_data = session_response.json()
session_id = session_response.cookies['session_id']
common = xmlrpc.client.ServerProxy('{}/xmlrpc/2/common'.format(url))
uid = common.authenticate(db, username, password, {})
# Create a new XML-RPC client object
models = xmlrpc.client.ServerProxy('{}/xmlrpc/2/object'.format(url))
invoice_id = 21566
# Download the PDF file for the first invoice in the list
invoice = models.execute_kw(db, uid, password, 'account.move', 'read', [invoice_id], {'fields': ['name']})
pdf_file = models.execute_kw(db, uid, password, 'account.move.send', 'action_send_and_print', [4,[invoice_id]])
# Call the URL and send authorization
# Set the cookie value in the request headers
headers = {'Cookie': f'session_id={session_id}'}
# Call the URL with the specified cookie value
download_url = f'{url}{pdf_file["url"]}'
response = requests.get(download_url, headers=headers)
