我尝试基于此示例向channeladvisor API发出批处理请求：
我的请求看起来像这样：

Content-Type: multipart/mixed; boundary=938fabdd69a541beb904b703514f8bc3

我正在使用python请求库和一点点黑客来实现这一点 . 使用邮差时，这很好用 . 我得到204状态 .
当我用python尝试它时：
data = {
'Value':{
'UpdateType': 'UnShipped',
'Updates': [{
'DistributionCenterID': 1,
'Quantity': 2
}]
}
}
headers = {
'Content-Type': 'application/json'
}
commands = []
commands.append(requests.Request('POST', 'https://api.channeladvisor.com/V1/Products(227657)/UpdateQuantity HTTP/1.1', json=data, headers=headers))
commands.append(requests.Request('POST', 'https://api.channeladvisor.com/V1/Products(227658)/UpdateQuantity HTTP/1.1', json=data, headers=headers))
commands.append(requests.Request('POST', 'https://api.channeladvisor.com/V1/Products(227659)/UpdateQuantity HTTP/1.1', json=data, headers=headers))
#-----------------------------------------------#
batch = BatchRequest()
files = batch.prepare_requests(commands)
r = requests.Request('POST', 'https://api.channeladvisor.com/v1/$batch?access_token='+self.access_token, files=files)
prepared = r.prepare()
prepared = batch.finalize_request(prepared)
batch.pretty_print_POST(prepared)
s = requests.Session()
resp = s.send(prepared)
我明白了：

我尝试了一切，真的绝望地问这个问题？感谢帮助
