HttpOpenRequest

所處動態程式庫的檔案名稱：WinINet.dll

HINTERNET hHttpFile = ::HttpOpenRequest(

hConnect, // 1 HINTERNET hHttpSession

"GET",// 2 LPCTSTR lpszVerb

"/MSDN/MSDNINFO/", // 3 LPCTSTR lpszObjectName

HTTP_VERSION, // 4 LPCTSTR lpszVersion

NULL,// 5 LPCTSTR lpszReferer

0, // 6 LPCTSTR FAR * lplpszAcceptTypes

INTERNET_FLAG_DONT_CACHE, // 7 DWORD dwFlags

0 // 8 DWORD dwContext

) ;

返回創建請求的句柄。

參數<1>的名稱為“hConnect”，類型為“整數型”。就是Internet的連線句柄

參數<2>的名稱為“lpszVerb”，類型為“文本型”。訪問方式。在網頁里只有get和post兩種方法

參數<3>的名稱為“lpszObjectName”，類型為“文本型”。頁面的地址

參數<4>的名稱為“lpszVersion”，類型為“文本型”。協定的版本“HTTP/1.1”現在通用的是這樣。貌似聽說過2.0，但是不懂是啥意思。

參數<5>的名稱為“lpszReferer”，類型為“文本型”。引用頁，抓包得到的refer

參數<6>的名稱為“lplpszAcceptTypes”，類型為“文本型”。

參數<7>的名稱為“dwFlags”，類型為“整數型”。2147483648

參數<8>的名稱為“dwContext”，類型為“整數型”。0

如果創建失敗。需要釋放Internetopen句柄和Internetconnect句柄

INTERNET_FLAG_HYPERLINK	Forces a reload if there was no Expires time and no Last-Modified time returned from the server when determining whether to reload the item from the network. WinInet函式禁用SSL / TLS證書，是基於對給定的主機名的請求伺服器返回檢查。WinInet函式對一個簡單的檢查，使用證書的主機名稱和簡單的通配符匹配規則的比較。
INTERNET_FLAG_IGNORE_CERT_CN_INVALID	Disables WinInet function checking of SSL/TLS-based certificates that are returned from the server against the host name given in the request.

INTERNET_FLAG_IGNORE_REDIRECT_TO_HTTP	Disables the ability of the WinInet functions to detect this special type of redirect. When this flag is used, WinInet functions transparently allow redirects from HTTPS to HTTP URLs.

INTERNET_FLAG_NO_UI	Disables the cookie dialog box.
INTERNET_FLAG_PRAGMA_NOCACHE	Forces the request to be resolved by the origin server, even if a cached copy exists on the proxy.
