我需要知道如何从HttpsWebRequestPost函数向我的php脚本提供过多的参数。
LPCWSTR additionalHeaders = L"Content-Type: application/x-www-form-urlencoded\r\n";
DWORD headersLength = -1;
string HttpsWebRequestPost(string domain, string url, string dat)
{
//Extra
LPSTR data = const_cast<char *>(dat.c_str());;
DWORD data_len = strlen(data);
wstring sdomain = get_utf16(domain, CP_UTF8);
wstring surl = get_utf16(url, CP_UTF8);
string response;
DWORD dwSize = 0;
DWORD dwDownloaded = 0;
LPSTR pszOutBuffer;
BOOL bResults = FALSE;
HINTERNET hSession = NULL,
hConnect = NULL,
hRequest = NULL;
// Use WinHttpOpen to obtain a session handle.
hSession = WinHttpOpen(L"WinHTTP Example/1.0",
WINHTTP_ACCESS_TYPE_DEFAULT_PROXY,
WINHTTP_NO_PROXY_NAME,
WINHTTP_NO_PROXY_BYPASS, 0);
// Specify an HTTP server.
if (hSession)
hConnect = WinHttpConnect(hSession, sdomain.c_str(),
INTERNET_DEFAULT_HTTP_PORT, 0);
// Create an HTTP request handle.
if (hConnect)
hRequest = WinHttpOpenRequest(hConnect, L"POST", surl.c_str(),
NULL, WINHTTP_NO_REFERER,
WINHTTP_DEFAULT_ACCEPT_TYPES,
0);
// Send a request.
if (hRequest)
bResults = WinHttpSendRequest(hRequest,
additionalHeaders,
headersLength,
(LPVOID)data,
data_len,
data_len,
0);
// End the request.
if (bResults)
bResults = WinHttpReceiveResponse(hRequest, NULL);
// Keep checking for data until there is nothing left.
if (bResults)
{
do
{
// Check for available data.
dwSize = 0;
if (!WinHttpQueryDataAvailable(hRequest, &dwSize))
printf("Error %u in WinHttpQueryDataAvailable.\n",
GetLastError());
// Allocate space for the buffer.
pszOutBuffer = new char[dwSize + 1];
if (!pszOutBuffer)
{
printf("Out of memory\n");
dwSize = 0;
}
else
{
// Read the data.
ZeroMemory(pszOutBuffer, dwSize + 1);
if (!WinHttpReadData(hRequest, (LPVOID)pszOutBuffer,
dwSize, &dwDownloaded))
printf("Error %u in WinHttpReadData.\n", GetLastError());
else
//printf("%s", pszOutBuffer);
response = response + string(pszOutBuffer);
// Free the memory allocated to the buffer.
delete[] pszOutBuffer;
}
} while (dwSize > 0);
}
// Report any errors.
if (!bResults)
printf("Error %d has occurred.\n", GetLastError());
// Close any open handles.
if (hRequest) WinHttpCloseHandle(hRequest);
if (hConnect) WinHttpCloseHandle(hConnect);
if (hSession) WinHttpCloseHandle(hSession);
return response;
}
和c++代码:
int main()
{
printf("%s", HttpsWebRequestPost("mywebspaceaddr", "test.php", "value=1000").c_str());
system("PAUSE");
return 0;
}
我的php看起来很简单:
<?php
$val = $_GET['value'];
echo 'value given:' . $val;
?>
我在控制台上只收到"value given:“文本,但没有收到任何值。
有人知道如何显示函数给出的值吗?
对于我糟糕的php知识:)

您的$_GET应为$_POST。很简单,是吧?
