Azure 函数未从 VS 部署 - 未找到 HTTP 触发器

Question

我是 Azure 函数和 python 的新手。我已经使用 python v2 编程模型创建了一个 Azure 函数，并且可以从 VS code 成功执行它。但是，当尝试使用 VS 代码扩展和 CLI 进行部署时，部署成功，但该功能没有出现。我已经尝试了网上建议的大部分选项，但没有解决这个问题。我已经被困在这个问题上有一段时间了。任何帮助将不胜感激。

注意：由于我的功能正在使用消费计划，所以我无法真正使用 kudu 来检查 wwwroot 目录。我已尝试按照建议使用 API 手动同步触发器，但该功能仍然没有出现。

import azure.functions as func
import logging
import psycopg2
import flask
app = func.FunctionApp(http_auth_level=func.AuthLevel.ANONYMOUS)
@app.route(route="InsertFileInfo")
def InsertFileInfo(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')
    # Connection string information
    host = "host"
    dbname = "dbname"
    user = "dbname"
    password = "password"
    sslmode = "require"
    # Construct connection string
    conn_string = "host={0} user={1} dbname={2} password={3} sslmode={4}".format(host, user, dbname, password, sslmode)
    # Get JSON payload from the HTTP request
    try:
        payload = req.get_json()
    except ValueError:
        return func.HttpResponse("Invalid JSON payload", status_code=400)
    file_details = payload.get('fileDetails', {})
    sender = payload.get('sender', {})
    workflow_id = payload.get('workflowID')
    workflow_event = payload.get('workflowEvent')
    # Extracting values from nested dictionaries
    created_at = file_details.get('createdAt')
    file_id = file_details.get('fileID')
    file_key = file_details.get('key')
    receiver_sha256_hash = file_details.get('receiverSHA256Hash')
    application_id = sender.get('applicationID')
    zone = sender.get('zone')
    # Connect to the database
    try:
        connection = psycopg2.connect(conn_string)
        cursor = connection.cursor()
     # SQL query to insert data into the table
        insert_query = """INSERT INTO file_info (created_at, file_id, file_key, receiver_sha256_hash, 
                            sender_applicationid, zone, workflow_id, workflow_event) 
                            VALUES (%s, %s, %s, %s, %s, %s, %s, %s)"""
        # Data tuple to be inserted
        data_tuple = (created_at, file_id, file_key, receiver_sha256_hash, application_id, zone, workflow_id, workflow_event)
        # Executing the SQL command
        cursor.execute(insert_query, data_tuple)
        # Committing the changes to the database
        connection.commit()
        # Close Cursor and Connection
        cursor.close()
        connection.close()
        return func.HttpResponse("Data inserted successfully", status_code=200)
    
    except Exception as e:
        logging.error(str(e))
        return func.HttpResponse("Error inserting data", status_code=500)

尝试使用下面的代码并将您的函数部署到基于消费的函数应用程序：-

我的函数HttpTrigger代码：-

import azure.functions as func
import logging

app = func.FunctionApp(http_auth_level=func.AuthLevel.ANONYMOUS)

@app.route(route="InsertFileInfo")
def InsertFileInfo(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')
    # Connection string information
    host = "host"
    dbname = "dbname"
    user = "dbname"
    password = "password"
    sslmode = "require"
    # Construct connection string
    conn_string = "host={0} user={1} dbname={2} password={3} sslmode={4}".format(host, user, dbname, password, sslmode)
    # Get JSON payload from the HTTP request
    try:
        payload = req.get_json()
    except ValueError:
        return func.HttpResponse("Invalid JSON payload", status_code=400)
    file_details = payload.get('fileDetails', {})
    sender = payload.get('sender', {})
    workflow_id = payload.get('workflowID')
    workflow_event = payload.get('workflowEvent')
    # Extracting values from nested dictionaries
    created_at = file_details.get('createdAt')
    file_id = file_details.get('fileID')
    file_key = file_details.get('key')
    receiver_sha256_hash = file_details.get('receiverSHA256Hash')
    application_id = sender.get('applicationID')
    zone = sender.get('zone')
    # Connect to the database
    try:
        connection = psycopg2.connect(conn_string)
        cursor = connection.cursor()
     # SQL query to insert data into the table
        insert_query = """INSERT INTO file_info (created_at, file_id, file_key, receiver_sha256_hash, 
                            sender_applicationid, zone, workflow_id, workflow_event) 
                            VALUES (%s, %s, %s, %s, %s, %s, %s, %s)"""
        # Data tuple to be inserted
        data_tuple = (created_at, file_id, file_key, receiver_sha256_hash, application_id, zone, workflow_id, workflow_event)
        # Executing the SQL command
        cursor.execute(insert_query, data_tuple)
        # Committing the changes to the database
        connection.commit()
        # Close Cursor and Connection
        cursor.close()
        connection.close()
        return func.HttpResponse("Data inserted successfully", status_code=200)
    
    except Exception as e:
        logging.error(str(e))
        return func.HttpResponse("Error inserting data", status_code=500)

输出：-

确保您的函数应用配置设置或环境变量中存在以下设置：-

"name": "AzureWebJobsFeatureFlags",
"value": "EnableWorkerIndexing",
