如何在docker selenium中设置下载目录

# 创建Docker容器
docker create --name my_container -it -p 4444:4444 selenium/standalone-chrome

# 安装Chrome浏览器驱动
docker exec -it my_container apt-get update
docker exec -it my_container apt-get install -y chromium-browser
docker exec -it my_container ln -s /usr/bin/chromium-browser /usr/bin/google-chrome

FROM selenium/standalone-chrome

# 设置下载目录
RUN mkdir /downloads && \
    chmod 777 /downloads && \
    echo "DOWNLOAD_DIR=/downloads" >> /etc/environment

# 构建Docker镜像
docker build -t my_selenium .

# 运行Docker容器，并将本地的下载目录与容器内的目录进行映射
docker run -d -p 4444:4444 -v /path/to/local/downloads:/downloads --name my_container my_selenium

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

# 创建Chrome浏览器实例
chrome_options = Options()
chrome_options.add_argument("--headless")
chrome_options.add_argument("--no-sandbox")
chrome_options.add_argument("--disable-dev-shm-usage")
chrome_options.add_argument("--disable-gpu")
chrome_options.add_argument("--disable-infobars")
chrome_options.add_argument("--disable-extensions")
chrome_options.add_argument("--disable-popup-blocking")
chrome_options.add_argument("--disable-logging")
chrome_options.add_argument("--window-size=1280,1024")
chrome_options.add_argument("--disable-notifications")
chrome_options.add_argument("--disable-default-apps")
chrome_options.add_argument("--disable-translate")
chrome_options.add_argument("--disable-background-networking")
chrome_options.add_argument("--disable-background-timer-throttling")
chrome_options.add_argument("--disable-renderer-backgrounding")

# 设置下载目录
prefs = {"download.default_directory": "/downloads"}
chrome_options.add_experimental_option("prefs", prefs)

driver = webdriver.Chrome(options=chrome_options)

# 执行其他Selenium操作

driver.quit()
