NO.008-飞书群机器人发送文件消息——By.杭州组

作者：启航

关键词：飞书，发送文件

一.问题背景

问题：

客户侧通过影刀自动处理退款信息表格之后，需要把处理好的表格文件发送到协同部门的群内，客户侧之前是手动发送文件，不是特别智能化，就想自动化把整个步骤都实现了

解法：

通过python调用飞书开放的api接口实现

二.解决思路

1.飞书开发者后台创建应用

https://open.feishu.cn/

2.飞书开放平台添加机器人

https://open.feishu.cn/app/cli_a23a93b963fa1013/capability

3.开通权限

https://open.feishu.cn/app/cli_a23a93b963fa1013/auth


需要开通以下权限

4.飞书群里添加群机器人

添加创建的群机器人

5.安装requests包和requests_toolbelt包

安装requests_toolbelt包的时候会报错，但是包已经安装上了不影响使用

6.获取tenant_access_token

https://open.feishu.cn/document/ukTMukTMukTM/ukDNz4SO0MjL5QzM/auth-v3/auth/tenant_access_token_internal#365d3b16

def get_token(app_id,app_secret):
    url = 'https://open.feishu.cn/open-apis/auth/v3/tenant_access_token/internal'
    data = {
        "Content-Type":"application/json; charset=utf-8",
        "app_id": app_id,
        "app_secret": app_secret
    }
    response = requests.request("POST", url, data=data)
    return json.loads(response.text)['tenant_access_token']

7.获取 chat_id

https://open.feishu.cn/document/uAjLw4CM/ukTMukTMukTM/reference/im-v1/chat/list

def get_chat_id(app_id,app_secret):
    url = "https://open.feishu.cn/open-apis/im/v1/chats?page_size=20"
    payload = ''
    tenant_access_token = get_token(app_id,app_secret)
    Authorization = 'Bearer ' + tenant_access_token
    headers = {
    'Authorization': Authorization
    }
    response = requests.request("GET", url, headers=headers, data=payload)
    return json.loads(response.text)['data']['items'][0]['chat_id']

8.上传文件获取文件路径

https://open.feishu.cn/document/uAjLw4CM/ukTMukTMukTM/reference/im-v1/file/create

# 获取文件二进制路径
# file_type 文件类型 file_name 文件名称+后缀名  file_path 本地文件路径
# type_file 类型 参考 https://www.w3school.com.cn/media/media_mimeref.asp
def get_filepath(file_type,file_name,file_path,app_id,app_secret,type_file):
  url = "https://open.feishu.cn/open-apis/im/v1/files"
  form = {'file_type': file_type,
          'file_name': file_name,
          'file':  (file_name, open(file_path,'rb'), type_file)} 
  multi_form = MultipartEncoder(form)
  tenant_access_token = get_token(app_id,app_secret)
  Authorization = 'Bearer ' + tenant_access_token
  headers = {
    'Authorization': Authorization
  }
  headers['Content-Type'] = multi_form.content_type
  response = requests.request("POST", url, headers=headers, data=multi_form)
  return json.loads(response.content)['data']['file_key']

9.发送消息

https://open.feishu.cn/document/uAjLw4CM/ukTMukTMukTM/im-v1/message/create_json#c92e6d46

# 发送文件
def send(file_type,file_name,file_path,app_id,app_secret,type_file):
    url = "https://open.feishu.cn/open-apis/im/v1/messages"
    params = {"receive_id_type":"chat_id"}
    msg = "file"
    msgContent = {
        "file": msg,
    }
    receive_id = get_chat_id(app_id,app_secret)
    file_path = get_filepath(file_type,file_name,file_path,app_id,app_secret,type_file)
    file_key = json.dumps({"file_key":file_path})
    req = {
        "receive_id": receive_id, 
        "msg_type": "file",
        "content":file_key
    }
    payload = json.dumps(req)
    tenant_access_token = get_token(app_id,app_secret)
    Authorization = 'Bearer ' + tenant_access_token
    headers = {
        'Authorization': Authorization,
        'Content-Type': 'application/json'
    }
    response = requests.request("POST", url, params=params, headers=headers, data=payload)

三.全部代码

  form = {'file_type': file_type,
          'file_name': file_name,

  multi_form = MultipartEncoder(form)
  tenant_access_token = get_token(app_id,app_secret)
  Authorization = 'Bearer ' + tenant_access_token
  headers = {
    'Authorization': Authorization
  }
  headers['Content-Type'] = multi_form.content_type
  response = requests.request("POST", url, headers=headers, data=multi_form)
  return json.loads(response.content)['data']['file_key']

# 发送文件
def send(file_type,file_name,file_path,app_id,app_secret,type_file):

    receive_id = get_chat_id(app_id,app_secret)
    file_path = get_filepath(file_type,file_name,file_path,app_id,app_secret,type_file)
    file_key = json.dumps({"file_key":file_path})

    tenant_access_token = get_token(app_id,app_secret)
    Authorization = 'Bearer ' + tenant_access_token
    headers = {
        'Authorization': Authorization,
        'Content-Type': 'application/json'
    }
    response = requests.request("POST", url, params=params, headers=headers, data=payload)

四.调用

• file_type：文件类型

• file_name：带后缀名的文件名

• file_path：本地文件的路径

• app_id：应用id

• app_secret：应用秘钥

• type_file：Mime 类型 https://www.w3school.com.cn/media/media_mimeref.asp
