[C#] TestHttpPost(测试Http的POST方法)发布v1.2版,增加增加输出文件、设置请求头的功能


作者: zyl910

最近在调试Http POST协议的接口时,对 TestHttpPost 进行了改进,增加了增加输出文件、设置请求头的功能。故发布了发布v1.2版。

一、变更说明

v1.2的变更说明——

  • 框架版本改为.NET Framework 4.5. 因为 WIndows 7、Windows Server 2008等操作系统自带了.NET Framework 4.5或更高版本, 节省了安装.NET 运行时的工作.
  • 增加输出文件的功能. 增加了“OutputFile”的复选框及文本框.
  • 增加设置请求头的功能. 增加了“Header”选项卡, 其中可以设置请求头。每一行的格式为“key: value”.

是在 hezlog 的改进版的基础上改造的。感谢 hezlog 的贡献.

二、使用介绍

默认是“POST”模式。在最上面的文本框中输入Url地址,然后在“Post Data”文本框中输入Post参数,再点击“Go”按钮发送请求。
如果想使用“GET”模式。便点击左上角的组合框,选择“GET”模式,再点击“Go”按钮发送请求。

下面介绍了更多用法。

  • 当发现回应内容乱码时。点击“Response Encoding”组合框,选择合适的编码。再点击“Go”按钮发送请求。
  • 当需要查看详细日志时。勾选“log header”复选框。再点击“Go”按钮发送请求。
  • 当需要输出文件时。勾选“Output file”复选框,随后在旁边的文本框里输入“输出文件名”。再点击“Go”按钮发送请求。
  • 当需要设置请求头时。点击“Header”切换到该选项卡,随后在其中的文本框里输入请求头的内容,例如“Cookie: abc”。再点击“Go”按钮发送请求。
