Mac公证脚本-Web公证方式

公证方式

Mac 公证方式有三种

这里 Notary API 有较大的优势，之前 altool 脚本公证的方式我们已经做过，由于 2023/11/01 将被弃用，考虑后续跨平台的需要，使用 notary API 进行脚本自动化公证

https://developer.apple.***/documentation/notaryapi/submitting_software_for_notarization_over_the_web

流程

具体的流程大概如下：

1. 获取 API密钥 (Private Key)
2. 使用 API密钥 (Private Key) 生成 JSON Web Token (JWT) , 相当于授权令牌 token
3. 请求 Notary API 并在 HTTP 请求头中，携带 JWT 内容
4. 得到请求结果

1. 获取 API密钥

https://developer.apple.***/documentation/appstoreconnectapi/creating_api_keys_for_app_store_connect_api

官方文档阐述

1. 登录App Store Connect
2. 选择 [用户和访问] 这栏 ，然后选择API Keys选项卡
3. 单击生成API密钥或添加(+)按钮。
4. 输入密钥的名称。
5. 在A***ess下，为密钥选择角色
6. 点击生成
7. 点击下载秘钥 （注意下载后苹果不再保存，你只能下载一次）

根据上述流程获取你的 API 秘钥

2. 生成令牌 Token

https://developer.apple.***/documentation/appstoreconnectapi/generating_tokens_for_api_requests

2.1. 环境安装

1. 根据 https://jwt.io/libraries 所述，安装 pyjwt 库
2. 由于本地环境 python3, 使用 pip3 install pyjwt 安装, 并参考官网使用说明 https://pyjwt.readthedocs.io/en/stable/usage.html#encoding-decoding-tokens-with-hs256
3. pyjwt 依赖 cryptography 库，需要额外安装 pip3 install cryptography
4. 文件上传依赖 boto3 库，pip3 install boto3

2.2. JWT Encode/Decode

参考 https://developer.apple.***/documentation/appstoreconnectapi/generating_tokens_for_api_requests 所述进行设置，值得注意的是，苹果会拒绝大多数设置过期时间为 20 分钟以上的 JWT 票据，所以我们需要间隔生成 JWT

1. header

{
    "alg": "ES256",
    "kid": "2X9R4HXF34",
    "typ": "JWT"
}

1. body

{
    "iss": "57246542-96fe-1a63-e053-0824d011072a",
    "iat": 1528407600,
    "exp": 1528408800,
    "aud": "appstoreconnect-v1",
    "scope": [
        "GET /notary/v2/submissions",
        "POST /notary/v2/submissions",
    ]
}

1. API 秘钥

对应的生成逻辑如下

def get_jwt_token():
    # 读取私钥文件内容
    with open('./AuthKey_xxxxx.p8', 'rb') as f:
        jwt_secret_key = f.read()


    # 获取当前时间
    now = datetime.datetime.now()
    # 计算过期时间（当前时间往后 20 分钟）
    expires = now + datetime.timedelta(minutes=20)

    # 设置 JWT 的 header
    jwt_header = {
        "alg": "ES256",
        "kid": "2X9R4HXF34",
        "typ": "JWT"
    }

    # 检查文件是否存在
    if os.path.exists("./jwt_token"):
        # 读取
        with open('./jwt_token', 'rb') as f:
            jwt_pre_token = f.read()

        
        print('[info]','jwt token %s' % (jwt_pre_token))
        try:
            decoded = jwt.decode(
                jwt_pre_token,
                jwt_secret_key,
                algorithms="ES256",
                audience="appstoreconnect-v1"
            )
        except Exception as e:
            print('[error]', 'decode exception %s' % (e))
        else:
            exp = datetime.datetime.fromtimestamp(decoded["exp"])

            if exp - datetime.timedelta(seconds=60) < now:
                print("jwt token 已过期，重新生成")
            else:
                print("jwt token 有效，使用之前token")
                return jwt_pre_token

    

    # 设置 JWT 的 payload
    jwt_payload = {
        "iss": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
        "iat": int(now.timestamp()),
        "exp": int(expires.timestamp()),
        "aud": "appstoreconnect-v1",
        "scope": [
            "GET /notary/v2/submissions",
            "POST /notary/v2/submissions",
        ]
    }
    print('[info]', 'jwt_header %s' % (jwt_header), 'jwt_payload %s' % jwt_payload)
    token = jwt.encode(
             jwt_payload,
             jwt_secret_key,
             algorithm="ES256",
             headers=jwt_header,
        )

    # 打开文件，如果文件不存在则创建文件
    with open("./jwt_token", "w") as f:
        # 将 token 写入文件
        f.write(token)

    print('[info]', 'jwt token is %s' % (token))
    return token

3. 公证上传

公证处理的流程如下

1. POST https://appstoreconnect.apple.***/notary/v2/submissions 请求submission s3 上传凭证
2. 使用 boto3 框架根据获取的凭证信息，查询一次公证状态，如果非 A***epted 状态，进行上传文件。（阻塞式）

file_md5=None
def post_submissison(filepath): 
    global file_md5
    body = get_body(filepath)
    token = get_jwt_token()
    file_md5 = get_md5(filepath)
    
    # 指定文件夹路径
    folder_path = './output'
    # 缓存路径
    cache_path = f"{folder_path}/{file_md5}"
    # 检查文件夹是否存在
    if not os.path.exists(folder_path):
        # 如果文件夹不存在，则创建文件夹
        os.makedirs(folder_path)
    else:
        # 如果文件夹已经存在，则进行相应的处理
        print("[info]", '%s 已经存在' % folder_path)


    # 检查文件是否存在
    if os.path.exists(cache_path):
        # 读取
        with open(cache_path, 'rb') as f:
            string = f.read().decode()
            output = json.loads(string)
            print('[info]', '使用上次 submission s3 上传凭证 = %s' % (output))

    else:
        resp = requests.post("https://appstoreconnect.apple.***/notary/v2/submissions", json=body, headers={"Authorization": "Bearer " + token})
        resp.raise_for_status()
        output = resp.json()
        print('[info]', '获取 submission s3上传凭证 = %s' % (output))
        # 打开文件，如果文件不存在则创建文件
        with open(cache_path, "w") as f:
            # 将 resp 写入文件
            f.write(resp.content.decode())

    # 读取 output 中的内容
    aws_info = output["data"]["attributes"]
    bucket = aws_info["bucket"]
    key = aws_info["object"]
    # sub_id = output["data"]["id"]
    # 如果已经完成了公证
    state = get_submission_state(filepath, True)
    if state == True:
        print('[info]', 'file %s alreay finished notarization' % (filepath))
        staple_pkg(filepath)
        exit(0)
        
    s3 = boto3.client(
             "s3",
             aws_a***ess_key_id=aws_info["awsA***essKeyId"],
             aws_secret_a***ess_key=aws_info["awsSecretA***essKey"],
             aws_session_token=aws_info["awsSessionToken"],
             config=Config(s3={"use_a***elerate_endpoint": True})
        )

    print('[info]', 'start upload files ...... please wait 2-15 mins')
    # 上传文件
    s3.upload_file(filepath, bucket, key)
    
    print('[info]', 'upload file ***plete ...')

1. 查询公证状态，A***epted 、In Progress、Invalid 目前探测到这三种状态

def get_submission_state(filepath, once=False):
    print('[info]', 'get_submission_state %s %s ' % (filepath, once))
    global file_md5
    if not file_md5:
        file_md5 = get_md5(filepath)
    # 指定文件夹路径
    folder_path = './output'
    # 缓存路径
    cache_path = f"{folder_path}/{file_md5}"
    # 检查文件是否存在
    if os.path.exists(cache_path):
        # 获取文件大小
        file_size = os.path.getsize(cache_path)
        if file_size == 0:
            # 文件内容为空
            print('[info]', ' %s 内容为空，未获取到submission信息' % (filepath))
            return False
        else:
            # 读取缓存内容
            with open(cache_path, 'rb') as f:
                string = f.read().decode()
                output = json.loads(string)
    else:
        return False

    sub_id = output["data"]["id"]
    url = f"https://appstoreconnect.apple.***/notary/v2/submissions/{sub_id}"
    ret = False
    while True:
        try:
            # 获取submission
            token = get_jwt_token()
            resp = requests.get(url, headers={"Authorization": "Bearer " + token})
            resp.raise_for_status()
        except Exception as e:
            # 异常处理
            print("[Error]", ' %s get status failed, code = %s ' % filepath % resp.status_code)
            return False
        else:
            # 200 正常返回处理
            # 检查 status
            resp_json = resp.json()
            print('[info]', 'GET %s resp is %s , header is %s' % (url,resp_json,resp.headers))

            status = resp_json["data"]["attributes"]["status"]
            if status == "A***epted":
                print("[info]", ' %s notarization su***esfull' % filepath)
                ret = True
                break
            if status == "Invalid":
                print("[info]", ' %s notarization failed' % filepath)
                ret = False
                break
            
            if once == False:
                # 暂停 30 秒
                time.sleep(30)
            else:
                print("[info]", 'get_submission_state run once')
                break
    if once == False:
        print_submission_logs(sub_id)
    return ret

1. 获取日志内容

def print_submission_logs(identifier):
    try:
        url = f"https://appstoreconnect.apple.***/notary/v2/submissions/{identifier}/logs"
        token = get_jwt_token()
        resp = requests.get(url, headers={"Authorization": "Bearer " + token})
        resp.raise_for_status()
    except Exception as e:
        print("[Error]", '/notary/v2/submissions/%s/logs failed, code = %s ' % (identifier, resp.status_code))
    else:
        resp_json = resp.json()
        print('[info]', 'notarization %s logs is %s' % (identifier, resp_json))

1. 如果 步骤3 查询到结果为 A***epted，则使用 stapler 工具打上票据，进行分发

def staple_pkg(filepath):
    global file_md5
    if not file_md5:
        file_md5 = get_md5(filepath)
    # 完成公证
    subprocess.run(["xcrun", "stapler", "staple", filepath])
    now = datetime.datetime.now()
    # 验证公证结果
    temp_output_file = f"./temp_file_{file_md5}"
    with open(temp_output_file, "w") as f:
        subprocess.run(["xcrun", "stapler", "validate", filepath], stdout=f, stderr=subprocess.STDOUT)

    # 读取验证结果
    with open(temp_output_file, "r") as f:
        validate_result = f.read()

    os.remove(temp_output_file)
    # 检查验证结果
    if "The validate action worked!" not in validate_result:
        print('[error]',"\033[31m[error] stapler validate invalid, may be notarization failed!\033[0m")
        return False
    else:
        print('[info]','staple_pkg su***esfull')
        return True

4. 脚本使用方式

脚本文件  https://github.***/CaicaiNo/Apple-Mac-Notarized-script/blob/master/notarize-web/notarize.py

在执行下列步骤前，请先阅读 Generating Tokens for API Requests | Apple Developer Documentation

1. 替换你的秘钥文件 (例如 AuthKey_2X9R4HXF34.p8)

private_key = f"./../../res/AuthKey_2X9R4HXF34.p8"

1. 设置你的 kid

 # 设置 JWT 的 header
    jwt_header = {
        "alg": "ES256",
        "kid": "2X9R4HXF34",
        "typ": "JWT"
    }

1. 设置你的 iss

# 设置 JWT 的 payload
    jwt_payload = {
        "iss": "57246542-96fe-1a63-e053-0824d011072a",
        "iat": int(now.timestamp()),
        "exp": int(expires.timestamp()),
        "aud": "appstoreconnect-v1",
        "scope": [
            "GET /notary/v2/submissions",
            "POST /notary/v2/submissions",
        ]
    }

1. 调用脚本

python3 -u ./notarize.py --pkg "./Output/${PACKAGE_NAME}_$TIME_INDEX.pkg" --private-key "./../../res/AuthKey_2X9R4HXF34.p8"

if [ $? -eq 0 ]; then
    echo "./Output/aTrustInstaller_$TIME_INDEX.pkg notarization su***essful"
    // 公证成功
else
    // 公证失败
    echo "./Output/aTrustInstaller_$TIME_INDEX.pkg notarization failed"
    exit 1
