Fiddler工具非常强大好用

传递一个json对象发post请求案例：

1.打开Fiddler，点击Composer选项卡

2.下拉框选择Post

3.输入请求的URL,比如：http://localhost:49194/api/user/

4.Request Headers中输入:

Content-Type: application/json; charset=utf-8

Content-Length: 398 (这个是你要和你请求正文的字符长度一致，可以不输入，自动计算)

5.输入,Requst Boy，比如：

{"UserName":"logic5","Password":"Test1234","FirstName":"Ivan","LastName":"Chen","LastLoginDate":"2010-01-01","Email":"[email protected]","CreateDate":"2010-01-01","LastPasswordChangedDate":"2010-01-01","LastLockoutDate":"2010-01-01","IsLockedOut":true,"IsApproved":false,"DisableDate":"2010-01-01","IsDisable":false,"profile":{"TINs":"743222298","ProviderId":168829,"UserName":"logic5"}}

点击Execute,操作成功！
