Linux POST 請求

curl

使用 curl 發送 POST 請求並讀取網站的響應：

$ curl url -d "key1=value1&key2=value2..."

-d：以POST方式提交用戶數據。 字符串參數形式類似於GET請求，每對 key=value 之間用 & 分隔。

[ming@localhost ~]$ url="http://httpbin.org/post"
[ming@localhost ~]$ curl $url -d "name=ming&contry=China"
{
  "args": {}, 
  "data": "", 
  "files": {}, 
  "form": {
    "contry": "China", 
    "name": "ming"
  }, 
  "headers": {
    "Accept": "*/*", 
    "Content-Length": "22", 
    "Content-Type": "application/x-www-form-urlencoded", 
    "Host": "httpbin.org", 
    "User-Agent": "curl/7.29.0"
  }, 
  "json": null, 
  "origin": "222.201.187.76, 222.201.187.76", 
  "url": "https://httpbin.org/post"
}

wget

使用 wget 發送 POST 請求並讀取網站的響應：

$ wget url --post-data "key1=value1&key2=value2..."

[ming@localhost ~]$ url="http://httpbin.org/post"
[ming@localhost ~]$ wget $url --post-data "name=ming&contry=China"
