python实现文件上传预览_【python-requests】实现文件上传

def upload_file(host, api,filepath, **kwargs):

url = host + api

querystring = {

"app_id": "10000",

"region": "en",

"lang": "zh-cn"

}

headers = {

}

file_name = filepath.split("/")[-1]

data = {

"version": 1,

"need_check": False,

"operator": "123"

}

files = {"file": (file_name, open(filepath, 'rb'), "text/plain")}

print(url)

r = requests.post(url, params=querystring, headers=headers, data=data,files=files)

return r.json()

上述方式支持multipart/form-data 方式，

坑：注意header里不要指定content-type类型，requests会自动生成，否则会报错

files里需要指定文件类型

text/plain

text/html

image/jpeg

image/png

audio/mpeg

audio/ogg

audio/*

video/mp4

application/*

application/json

application/javascript

application/ecmascript

application/octet-stream
