curl使用

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

Windows 下的 curl

Windows 下PowerShell中的curl实际调用的是Invoke-WebRequest
