怎么使用linukshell循环爬取网页上下页的josn数据 。
你可以使用 bash 脚本和网络工具(如 curl 或 wget)来实现爬取网页上下页 JSON 数据的循环过程。以下是一个例子:
#!/bin/bash
# URL of the first page to crawl
url="https://example.com/data.json?page=1"
# Loop through all pages
while true; do
# Download the current page
json=$(curl "$url")
# Parse the JSON data
# ...
# Extract the URL of the next page
next_url=$(echo "$json" | jq '.next_page_url')
# Check if there is a next page
if [ "$next_url" == "null" ]; then
break
fi
# Update the URL for the next iteration
url="$next_url"
done
注意:需要先安装 jq,它是一个用于处理 JSON 的命令行工具。
