一、将pdf旋转的通用方法
def rotate_pdf(self, pdf, angle):
"""
rotateClockwise(90)
这里的pdf传:bytes类型
这里的angel：角度 90 180 270 360度
getNumPages将每一页都旋转
"""
writer = PdfFileWriter()
reader = PdfFileReader(io.BytesIO(pdf), strict=False)
for page in range(0, reader.getNumPages()):
page = reader.getPage(page)
page.rotateClockwise(angle)
writer.addPage(page)
with io.BytesIO() as _buffer:
writer.write(_buffer)
return
二、通过接口将report打印，并提供下载
'/fmcg/download/pdf', type='http', auth="public", csrf=False, cors='*')
def melon_download_pdf(self, **kw):
"""下载图片接口：直接返回的是一个文件对象，可直接下载"""
data = []
id = kw['id']
#获取打印单的 bytes文件
report = request.env.ref('sale.action_transaction_report').with_user(SUPERUSER_ID)._render_qweb_pdf(int(kw['id']))
report_datas = self.rotate_pdf(report[0],90)
data = io.BytesIO(report_datas)
return http.send_file(data, filename='transaction_order.pdf', as_attachment=True)
三、接口里面传附件方式：1、传文件对象；
2、传地址；
'/upload/image/api', type='http', methods=['POST'], auth="public", csrf=False, cors='*')
def upload_store_image(self, **kw):
"""上传图片接口:sale.order
这里是文件对象
"""
_logger.info("---------上传图片接口--kw--------------------------:%s", kw)
if not kw['file']:
return json.dumps({'result': 'fail', 'message': 'no image'})
base64_data = base64.b64encode(kw['file'].read())
attachment = request.env['ir.attachment'].sudo().create({
'name': kw['file'].filename,
'datas': base64_data,
'res_model': 'sale.order',
})
image = '%s/web/image/%s-%s' % (url_path, str(attachment.id), attachment.checksum) if attachment else ''
return json.dumps({'code': 200, 'message': 'success', 'data':[]})
