本文介绍curl工具的常见用法，使用 https://httpbin.org/ 这个网站作为 Http Server 进行测试

常见用法

官网：https://curl.se/

最简单的GET请求

[root@localhost ~]# curl https://httpbin.org/get
{"args": {},"headers": {"Accept": "*/*","Host": "httpbin.org","User-Agent": "curl/7.61.1","X-Amzn-Trace-Id": "Root=1-697b7bb9-72d9720837c940ea3b545d06"},"origin": "223.104.83.109","url": "https://httpbin.org/get"
}

不同的请求方式，使用 -X 指定请求方法即可

# POST请求
curl -X POST https://httpbin.org/post
# PUT请求
curl -X PUT https://httpbin.org/put
# DELETE请求
curl -X DELETE https://httpbin.org/delete

带参数请求，请求即Payloads

# JSON: Content-Type
curl -X POST https://httpbin.org/post \-H "Content-Type: application/json" \-d '{"username": "jdoe", "active": true}'# 表单：application/x-www-form-urlencoded
curl -X POST https://httpbin.org/post \-d "name=John+Doe" \-d "email=john@example.com"# 上传文件： multipart/form-data
curl -X POST https://httpbin.org/post -F "file=@localfile.txt"# body比较大，不方便加在命令行，将POST body放进文件里读取
curl -X POST https://httpbin.org/post \-H "Content-Type: application/json" \-d @data.json

设置请求头

curl -H "X-My-Header: CoolValue" https://httpbin.org/headers

设置Cookies

curl -b "session_id=12345; preference=dark_mode" https://httpbin.org/cookies# 访问接口，并将Cookies保存到文件
curl -c cookies.txt https://httpbin.org/cookies/set/mycookie/value# 将Cookies保存到文件进行读取
curl -b cookies.txt https://httpbin.org/cookies
