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¶m2=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
