使用powershell制作http请求界面工具

发表于 2020-11-21 分类于工具评论次数：阅读次数：
直接使用powershell程序编写应用窗口，完成http请求，优点是不需要安装任何程序，因为windows10自带powershell。如果需要使用文件上传则需要安装powershell7。
说明

把下面的代码放到后缀名为.ps1的文件中
右键打开，打开方式为Windows PowerShell
打开之后界面如下图：
参数格式说明：
- header: 请求头，以换行符分割每一条
- cookie: 以;分割，如a=aaa;b=bbb
- content: 请求内容，如果contentType选的为json，则为json格式，如{"a":"aaa","b":"bbb"}, 如果contentType选的为x-www-form-urlencoded,则为form结构，如a=aaa&b=bbb
请求示例如下图：
增加文件上传，上传文件需要powershell7，使用form-data类型，content有则格式为json，并且上传文件名不能含中文
