作者 | JackTian 来源 | 公众号：杰哥的IT之旅（ID：Jake_Internet）前言在日常工作中，我们所经常使用的 Linux 服务器操作系统，无论是要查看网络设备的信息、管理网络接口、下载文件、调试网络问题还是查看网络的统计数据，都可以在终端下用命令来完成。 ifconfig / ip a 命令 ifconfig 与 ip a 是类似的，用于输出网络接口配置、调优等各种选项，可便捷的查看 IP 地址和其它网络接口的信息以及查看所有启用的网络接口的状态、名字或指定网络接口名字来显示一个接口的信息。 # ip a # ifconfig # ifconfig ens32 ifdown / ifup ifdown 和 ifup 跟命令 ifconfig down 和 ifconfig up 功能是一致的，主要用来给指定网络接口名来操作启用或禁用的状态，在 Ubuntu 上需要 root 权限可使用 sudo 来执行。 # sudo ifdown eth0 # sudo ifup eth0 ping ping 发送报文到指定的 IP 地址，可测试联通性，使用 -c 参数，可以指定发送报文包的个数。执行 ping 命令将使用 ICMP 传输协议。如能 ping 通将进行输出要求响应的信息，ping 不通时，将显示没有路由或拒绝等相关性的响应信息

阅读更多关于 Requests Library Force Use of HTTP/1.1 On HTTPS Proxy CONNECT

问题 I am having a problem with a misbehaving HTTP Proxy server. I have no control over the proxy server, unfortunately -- it's an 'enterprise' product from IBM. The proxy server is part of a service virtualization solution being leveraged for software testing. The fundamental issue (I think*) is that the proxy server sends back HTTP/1.0 responses. I can get it to work fine from SOAP UI ( A Java application) and curl from the command line, but Python refuses to connect. From what I can tell,

Correct format for multiline '--data' in curl query to graphql endpoint?

阅读更多关于 Correct format for multiline '--data' in curl query to graphql endpoint?

问题 I'm passing "--data" via curl to a GraphqQL API endpoint. I want to be able to pass the data in 'prettified' form, e.g. as in GraphiQL browser, { alpha { param1 param2 } } Atm, my formatting inside the data -- namely, re: line returns -- isn't handled properly.
