我试图将一些JSON发布到Service Now API（Service Desk软件），这是一个非常烦人的问题。
从PowerShell发送时效果很好，但在C＃中我只是
＆＃34; StatusCode：BadRequest，Content-Type：application / json; charset = UTF-8，Content-Length：-1）＆＃34;
留言
＆＃34; {\＆＃34;错误\＆＃34;：{\＆＃34; detail \＆＃34;：\＆＃34; Cannod decode：java.io.StringReader@399624 \＆ ＃34;，\＆＃34;消息\＆＃34;：\＆＃34;读取请求时出现异常\＆＃34;}，\＆＃34;状态\＆＃34;：\＆＃34;失败\＆＃34;}＆＃34;
除了C＃需要""，{{和}}转义字符这一事实外，请求JSON 完全相同。
调试时，我粘贴了保存的正文字符串并对json验证器进行了验证。
我该怎么调试呢？非常感谢任何帮助。
