python发送post请求的几种形式

根据post请求头的content-type不同而不同：
1. content-type为"application/x-www-form-urlencoded"：

from urllib import parse
headers = {'content-type': 'application/x-www-form-urlencoded'}
url = "{0}".format(token)
with open(path, "rb") as video:
    base64_video = base64.b64encode(video.read()).decode()
content = {'type': 'video','video_base64': base64_video}
data= parse.urlencode(content)
try:
    response = requests.post(url=url,
                                 data=data,
                                 headers=headers,
                                 )
    res = response.json()
    msg = res.get("error_msg")
    xxx
except Exception as e:
    xxx

2.content-type为"application/json"：

headers = {'content-type': 'application/json'}
url = "{0}".format(token)
with open(path, "rb") as video:
    base64_video = base64.b64encode(video.read()).decode()
try:
    response = requests.post(url=url,
                                 data=json.dumps([{
                                     "video": base64_video ,
                                     "type": "BASE64",
                                 }]),
                                 headers=headers,
                                 )
    res = response.json()
    msg = res.get("error_msg")
    xxx
except Exception as e:
    xxx

3.content-type为"form-data"：

headers = {
    "Cookie": "session_id=xxxxxx"
}
url = "{0}/df/upload".format(host)
content_type = "video/mp4"
#content_type = "image/jpg"
files = {
    "file": (os.path.basename(file_path), open(file_path, "rb"), content_type),
}
data = {
     "type": 1
}
if tid:
    data["tid"] = tid

try:
    response = requests.post(url, files=files, data=data, headers=headers)
    res = response.json()
    msg = res.get("error_msg")
    xxx
except Exception as e:
    xxx
