3、curl -x proxy url(使用代理获取网页文本信息)

                                        /**/                        
Welcome to nginx on Fedora!
        
            
This page is used to test the proper operation of the            nginx HTTP server after it has been            installed. If you can read this page, it means that the            web server installed at this site is working            properly.
            
                
Website Administrator
                
                    
This is the default index.html page that                    is distributed with nginx on                    Fedora.  It is located in                    /usr/share/nginx/html.
                    
You should now put your content in a location of                    your choice and edit the root configuration                    directive in the nginx                    configuration file                    /etc/nginx/nginx.conf.
                
            
            
                                            
        
    

4、curl -X POST –header”Content-Type:application/json” –data ‘{}’ url (使用post模拟json格式请求接口)

curl -X POST --header "Content-Type:application/json"  --data '{}'  127.0.0.1:8088/user/getAllUserInfo

{"resultCode":"0","resultMsg":"成功","data":{"userList":[{"id":"a6fc8f27-e598-11e8-ba67-00163e14685b","name":"tom","age":"18","address":"北京1","stage":"NBA"},{"id":"24793d7c-e199-11e8-ba67-00163e14685b","name":"tom","age":"18","address":"北京3","stage":"NBA"},{"id":"247acf89-e599-11e8-ba67-00163e14685b","name":"jerry","age":"18","address":"深圳22","stage":"NBA"},{"id":"247cdafc-e599-11e8-ba67-00163e14685b","name":"james","age":"38","address":"广州d4","stage":"NBA"},{"id":"247ed96c-e599-11e8-ba67-00163e14685b","name":"curry","age":"58","address":"上海fv","stage":"NBA"},{"id":"24805b4e-e599-11e8-ba67-00163e14685b","name":"kaven","age":"78","address":"陇县","stage":"NBA"},{"id":"2481f851-e599-11e8-ba67-00163e14685b","name":"durant","age":"68","address":"富平","stage":"NBA"}]}}
