导入数据至数据集时报错Meta endpoint! Unexpected status code: 502, with response body: None.

我的dify服务器是在内网环境，首先它需要通过代理去调用 LLM，但打开代理后调用 dify weaviate 服务会报错：Meta endpoint! Unexpected status code: 502, with response body: None. 所以，需要做的是：既要在调用LLM的时候走代理，又要调用 dify weaviate 服务的时候不走代理。 配置如下：

dify 是通过 docker compose 的方式运行起来的， 所以需要编辑 dify 的 docker-compose.yaml 文件。

...
services:
  # API service
  api:
    image: langgenius/dify-api:0.7.1
    restart: always
    environment:
      # Use the shared environment variables.
      <<: *shared-api-worker-env
      # Startup mode, 'api' starts the API server.
      MODE: api
      # 设置代理
      HTTP_PROXY: http://my-proxy.com:3128
      HTTPS_PROXY: http://my-proxy.com:3128
      # 不走代理的情况： 把 weaviate 服务添加到里面
      NO_PROXY: localhost,127.0.0.1,weaviate
    depends_on:
      - db
      - redis
    volumes:
      # Mount the storage directory to the container, for storing user files.
      - ./volumes/app/storage:/app/api/storage
    networks:
      - ssrf_proxy_network
      - default

  # worker service
  # The Celery worker for processing the queue.
  worker:
    image: langgenius/dify-api:0.7.1
    restart: always
    environment:
      # Use the shared environment variables.
      <<: *shared-api-worker-env
      # Startup mode, 'worker' starts the Celery worker for processing the queue.
      MODE: worker
      # 设置代理
      HTTP_PROXY: http://my-proxy.com:3128
      HTTPS_PROXY: http://my-proxy.com:3128
      # 不走代理的情况： 把 weaviate 服务添加到里面
      NO_PROXY: localhost,127.0.0.1,weaviate
    depends_on:
      - db
      - redis
    volumes:
      # Mount the storage directory to the container, for storing user files.
      - ./volumes/app/storage:/app/api/storage
    networks:
      - ssrf_proxy_network
      - default

# dify 的其他服务就不需要配置代理的设置了
