curl常用操作

可参照：http://www.voidcn.com/blog/Vindra/article/p-4917667.html

一、get请求 

curl "http://www.baidu.com"  如果这里的URL指向的是一个文件或者一幅图都可以直接下载到本地

curl -i "http://www.baidu.com"  显示全部信息

curl -l "http://www.baidu.com" 只显示头部信息

curl -v "http://www.baidu.com" 显示get请求全过程解析

wget "http://www.baidu.com"也可以

二、post请求

curl -d "param1=value1&param2=value2" "http://www.baidu.com"

三、json格式的post请求

curl -l -H "Content-type: application/json" -X POST -d '{"phone":"13521389587","password":"test"}' http://domain/apis/users.json

例如：

curl -l -H "Content-type: application/json" -X POST -d '{"ver": "1.0","soa":{"req":"123"},"iface":"me.ele.lpdinfra.prediction.service.PredictionService","method":"restaurant_make_order_time","args":{"arg2":""stable"","arg1":"{"code":["WIND"],"temperature":11.11}","arg0":"{"tracking_id":"100000000331770936","eleme_order_id":"100000000331770936","platform_id":"4","restaurant_id":"482571","dish_num":1,"dish_info":[{"entity_id":142547763,"quantity":1,"category_id":1,"dish_name":"[0xe7][0x89][0xb9][0xe4][0xbb][0xb7][0xe8][0x85][0x8a][0xe5][0x91][0xb3][0xe5][0x8f][0x89][0xe7][0x83][0xa7][0xe5][0x8f][0x8c][0xe6][0x8b][0xbc][0xe7][0x85][0xb2][0xe4][0xbb][0x94][0xe9][0xa5][0xad]","price":31.0}],"merchant_location":{"longitude":"121.47831425","latitude":"31.27576153"},"customer_location":{"longitude":"121.47831425","latitude":"31.27576153"},"created_at":1477896550,"confirmed_at":1477896550,"dishes_total_price":0.0,"food_boxes_total_price":2.0,"delivery_total_price":2.0,"pay_amount":35.0,"city_id":"1"}"}}' http://vpcb-lpdinfra-stream-1.vm.elenet.me:8989/rpc

ps：json串内层参数需要格式化

curl -u username:pass http://www.xxx.com

需要传递用户名密码校验的请求

curl -H "Authorization token:xxxxxx"  http://www.xxx.com

需要传递token校验的请求

curl -H "ContentType: text" --request GETDELETEPUT http://www.xxxx.com

需要指定http method的请求

curl -I http://www.xxx.com

只获取header信息

curl -H ""Content-Type: application/json"  -d '{"name":"name"}--request GETDELETEPUT http://www.xxxx.com

提交数据json格式

curl -H ""Content-Type: application/json"  -d 'a=1&b=2' --request GETDELETEPUT http://www.xxxx.com

 

$curl -o /dev/null -s -w %{time_connect}:%{time_starttransfer}:%{time_total} http://www.xxx.com

0.081:0.272:0.779

使用 cURL 度量 Web 站点的响应时间

通过 -o 参数发送到 /dev/null。 -s 参数去掉所有状态信息。-w参数让 curl 写出列出的计时器的状态信息：

time_connect     建立到服务器的 TCP 连接所用的时间
time_starttransfer     在发出请求之后，Web 服务器返回数据的第一个字节所用的时间
time_total         完成请求所用的时间

指定域名、指定主机、端口访问

curl -vod "https://at.tuandai.com/inviteActivity/awardFromHeaven/index.html" --resolve at.tuandai.com:443:119.23.84.172
