阿里云官方对地址参数的解释说明

代码

以下都是按照RTMP协议构建，如需其他协议或其他开发语言可以参考阿里官方文档：

https://help.aliyun.com/zh/live/user-guide/ingest-and-streaming-urls?spm=a2c4g.11186623.0.0.5b1c3b4040CpuK#04753bf543bde

官方给出的代码示例

import re
import time
import hashlib
import datetime
def md5sum(src):
    m = hashlib.md5()
    m.update(src)
    return m.hexdigest()
def a_auth(uri, key, exp):
    p = re.compile("^(rtmp://)?([^/?]+)(/[^?]*)?(\\?.*)?$")
    if not p:
        return None
    m = p.match(uri)
    scheme, host, path, args = m.groups()
    if not scheme: scheme = "rtmp://"
    if not path: path = "/"
    if not args: args = ""
    rand = "0"      # "0" by default, other value is ok
    uid = "0"       # "0" by default, other value is ok
    sstring = "%s-%s-%s-%s-%s" %(path, exp, rand, uid, key)
    hashvalue = md5sum(sstring.encode('utf-8'))
    auth_key = "%s-%s-%s-%s" %(exp, rand, uid, hashvalue)
    if args:
        return "%s%s%s%s&auth_key=%s" %(scheme, host, path, args, auth_key)
    else:
        return "%s%s%s%s?auth_key=%s" %(scheme, host, path, args, auth_key)
def main():
    # 待加密的推/播流地址，example.aliyundoc.com为推/播流域名，liveApp为AppName，liveStream为StreamName
    # 推流和播流URL采用同样的加密方法
    # AppName或StreamName不超过256字符，支持数字、大小写字母、短划线（-）、下划线（_）、等号（=）。
    uri = "rtmp://example.aliyundoc.com/liveApp/liveStream"  
    # 鉴权Key，推流地址使用推流域名URL鉴权Key，播流地址使用播流域名URL鉴权Key
    key = "<input private key>"                         
    # exp值为UNIX时间戳，单位秒，最终失效时间由该值加上域名URL鉴权有效时长决定
    # 比如您在此处设置exp为：当前时间+3600秒，那最终失效时间为：当前时间+3600秒+域名URL鉴权有效时长。如果设置exp为：当前时间，那最终失效时间为：当前时间+域名URL鉴权有效时长
    exp = int(time.time()) + 1 * 3600                   
    authuri = a_auth(uri, key, exp)                     
    print("URL : %s\nAUTH: %s" %(uri, authuri))
if __name__ == "__main__":
    main()

当时官方好像并没有给出Python代码的示例所以本人按照官方标准完成的下面代码，仅作参考一切以官方为准

import hashlib
import random
import string
import time


def md5(param):
    if param is None or len(param) == 0:
        return None
    md5_hash = hashlib.md5()
    md5_hash.update(param.encode('utf-8'))
    return md5_hash.hexdigest()

    else:

    print(f"RTMP URL: {rtmp_url}")
    print(f"HLS URL: {hls_url}")
    print(f"FLV URL: {flv_url}")


def main():
    app_name = ''.join(random.choices(string.ascii_letters + string.digits, k=5))
    stream_name = ''.join(random.choices(string.ascii_letters + string.digits, k=5))

    expire_time = 3600  # 过期时间
    pull_domain = "拉流域名"
    pull_key = "拉流URL鉴权Key"

    push_domain = "推流域名"

    general_pull_url(pull_domain, pull_key, app_name, stream_name, expire_time)
    generate_push_url(push_domain, push_key, app_name, stream_name, expire_time)


if __name__ == '__main__':
    main()
