python3 post数据在json文件中：

1. for very large files.

files = {'file': open('import.json')}
re = requests.post(url,data=open('import.json','rb'),headers=headers)
print(re.json())

2.If you want to send a smaller file, send it as a string.

contents = open('example.json', 'rb').read()
r = requests.post(url, data=contents, headers=headers)
