我试图以下列模式将一些文件和参数作为Multi-Part发布。我已经尝试过dict和list。 list
投了一个HTTP 415
。所以我继续dict
。我想在一个通用名称'file'下发布一些参数和多个文件(以及它们各自的文件名)。
字符串参数工作正常,错误在于文件上传
在多部分dict对象中传递的数据
multipart = {
'param1': 'paramVal1',
'param2': 'paramVal2',
'file': (("file1.xml", ByteIO), ("file1.xml", ByteIO)),
}
使用python-requests
requests.post(url='http://localhost:8888/upload',files=multipart)
引发错误

由于两个文件项具有相同的名称,因此无法使用字典,但您可以在SELECT
[Client Code] = Client_Code,
[Client Name] = Client_Name,
[Post Haircut Stock] = POST_HC_STK
FROM TableA
参数中使用元组列表。
对于表单数据的其余部分,请使用files
参数。
data
请求正文:
data = {
'param1': 'paramVal1',
'param2': 'paramVal2'
}
files = [
("file", ("file1.xml", open("file1.xml", "rb"), "text/xml")),
("file", ("file2.xml", open("file2.xml", "rb"), "text/xml"))
]
r = requests.post(url='http://localhost:8888/upload', data=data, files=files)
print(r.request.body)

'参数1'和' param2'不是正确的文件吗?
您的请求应如下所示:
body = {'param1': 'paramVal1', 'param2': 'paramVal2'}
files = (("file1.xml", ByteIO), (filename, "file2.xml")),
requests.post(url='http://localhost:8888/upload', files = files, json = body)
