%³��

<</Names <</Dests 4 0 R>> /Outlines 5 0 R /Pages 2 0 R /Type /Catalog>>
endobj

我用postman 是返回正常的，body都能显出先pdf的内容



无奈之下我只能使用原始方法：HttpWebRequest，HttpWebResponse 获取到了
也正常下载到了这个pdf文件



请问我是哪里写错了吗？
我是用fiddler获取到的代码

[C#] 纯文本查看 复制代码

private string GetHttp20230201150825()
{
	SufeiUtil.HttpHelper http = new SufeiUtil.HttpHelper();
	SufeiUtil.HttpItem item = new SufeiUtil.HttpItem()
	{
