已发送 Wininet headers

Question

要收到 headers，我可以使用 HttpQueryInfo 和 HTTP_QUERY_RAW_HEADERS_CRLF。例如：

HTTP/1.1 200 OK
P3P: CP="Facebook does not have a P3P policy. Learn why here: redacted"
X-Frame-Options: DENY
X-XSS-Protection: 0
Cache-Control: private, no-cache, no-store, must-revalidate
Access-Control-Allow-Credentials: true
Pragma: no-cache
Vary: Origin
X-UA-Compatible: IE=edge,chrome=1
Access-Control-Allow-Origin: https://www.facebook.com
Access-Control-Expose-Headers: X-FB-Debug, X-Loader-Length
public-key-pins-report-only: max-age=500; pin-sha256="WoiWRyIOVNa9ihaBciRSC7XHjliYS9VwUGOIud4PB18="; pin-sha256="r/mIkG3eEpVdm+u/ko/cwxzOMo1bk4TyHIlByibiA5E="; pin-sha256="q4PO2G2cbkZhZ82+JgmRUyGMoAeozA+BSXVXQWB8XWQ="; report-uri="http://reports.fb.com/hpkp/"

Connection: keep-alive

但是如何发送 headers？例如：

POST /ajax/bz HTTP/1.1
Host: www.facebook.com
User-Agent: Mozilla/5.0 (Windows NT 5.1; rv:50.0) Gecko/20100101 Firefox/50.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate, br
Content-Type: application/x-www-form-urlencoded
Referer: https://www.facebook.com/
Content-Length: 610
Cookie: datr=KpR3WHnG8o9SSyjynboqoEFi; fr=0cgVuSHdECAqWqoBP..BYd5Qq.1M.AAA.0.0.BYfAc8.AWVTBVEg; _js_reg_fb_ref=https%3A%2F%2Fwww.facebook.com%2F; _js_reg_fb_gate=https%3A%2F%2Fwww.facebook.com%2F
Connection: keep-alive

抱歉，如果我的 post 大部分被识别为代码，因为我知道我有时不清楚，我想确保人们理解我想要将 headers 发送到服务器收到的那些。

发送请求后（或至少收到 INTERNET_STATUS_REQUEST_SENT 状态事件后），您可以使用 HttpQueryInfo() 同时指定 HTTP_QUERY_RAW_HEADERS/_CRLF 和 HTTP_QUERY_FLAG_REQUEST_HEADERS 标志。
