Having problems with uploading a file from c++ to a PHP form. Iv seen the posts similar to my issue.
And according to the documentation laid out in each, and in HERE my code by all accounts should be correct.
I also cannot use CURL for my implementation. As much as I would like too.
Iv tried encoding all the data into BASE64 to alleviate any file data problems, but no dice.
Iv double checked my php.ini file to allow uploads. And tested the PHP page with a simple HTML page that allows me to upload a file. All good, the form gives correct results.
Basically the headers I send to the server is:
Host: dzwxgames.com
Connection: close
Content-Length: 418
Origin: http://dzwxgames.com
Content-Type: multipart/form-data; boundary=WrbKitFormBoundaryXtRo8bh7ZpnTrTwd
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.70 Safari/537.36
Pragma: no-cache
--WrbKitFormBoundaryXtRo8bh7ZpnTrTwd
Content-Disposition: form-data; name="file"; filename="02-11-2019 09-44.log"
Content-Type: text/plain;
Content-Transfer-Encoding: BASE64

--WrbKitFormBoundaryXtRo8bh7ZpnTrTwd--
Which my PHP page returns:
HTTP/1.1 200 OK
Date: Sun, 03 Nov 2019 09:09:19 GMT
Server: Apache/2.4.29 (Ubuntu)
Content-Length: 35
Connection: close
Content-Type: text/plain; charset=utf-8
NULL
Array
(
)
File does not exist.
The code for the php page is simple:
if (!isset($_FILES['file']['error'])){
var_dump($_FILES['file']);
print_r($_FILES);
throw new RuntimeException('File does not exist.');
}
Finaly my C++ Code is:
bool sendFileToRemoteServer(std::filesystem::path file, const std::string& url,const std::string& iaddr) {
std::string headder = ""; //Headder information
std::string datahead = "";
std::string content = "";
if (!File::fastFileToString(file.string(), content)) {
std::cout << "ERROR_FILE_OPEN" << std::endl;
return false;
}
content = base64_encode(reinterpret_cast<const unsigned char*>(content.c_str()),content.length());
datahead += "--WrbKitFormBoundaryXtRo8bh7ZpnTrTwd\r\n";
datahead += "Content-Disposition: form-data; name=\"file\"; filename=\"" + file.filename().string() +"\"\r\n"; //Content - Disposition : form - data; name = "fileToUpload"; filename = "testMac.cpp"
datahead += "Content-Type: text/plain;\r\n";
datahead += "Content-Transfer-Encoding: BASE64\r\n\n";
datahead += content;
datahead += "\r\n--WrbKitFormBoundaryXtRo8bh7ZpnTrTwd--\r\n";
//datahead = base64_encode(reinterpret_cast<const unsigned char*>(datahead.c_str()), datahead.length());
//Build Headder
headder += "Host: " + iaddr + "\r\n"; //Host: localhost
headder += "Connection: close\r\n"; //Connection : keep - alive
headder += "Content-Length: " + std::to_string(datahead.size()) + "\r\n"; //Content - Length : 800
headder += "Origin: http://dzwxgames.com\r\n";
//headder += "Content-Transfer-Encoding: base64\r\n";
headder += "Content-Type: multipart/form-data; boundary=WrbKitFormBoundaryXtRo8bh7ZpnTrTwd\r\n"; //Content - Type : multipart / form - data; boundary = WrbKitFormBoundaryXtRo8bh7ZpnTrTwd
headder += "User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.70 Safari/537.36\r\n"; //User - Agent: 1337
headder += "Pragma: no-cache\r\n\r\n";
std::cout << "SENT HEAD:" << std::endl;
std::cout << headder;
std::cout << datahead;
//Open internet connection
HINTERNET hSession = InternetOpen("WINDOWS", INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);
if (hSession == NULL){
printLastError(GetLastError());
printf("ERROR_INTERNET_OPEN");
return false;
}
HINTERNET hConnect = InternetConnect(hSession, iaddr.c_str(), INTERNET_DEFAULT_HTTP_PORT, NULL, NULL, INTERNET_SERVICE_HTTP, 0, 1);
if (hConnect == NULL){
printLastError(GetLastError());
printf("ERROR_INTERNET_CONN");
return false;
}
HINTERNET hRequest = HttpOpenRequest(hConnect, (const char*)"POST", _T(url.c_str()), NULL, NULL, NULL, INTERNET_FLAG_RELOAD, 1);
if (hRequest == NULL){
printLastError(GetLastError());
printf("ERROR_INTERNET_REQ");
return false;
}
if (!HttpSendRequestA(hRequest, headder.c_str(), headder.size(), (void*)datahead.c_str(), datahead.size())){
printLastError(GetLastError());
printf("ERROR_INTERNET_SEND");
return false;
}
//Request Done, get responce
DWORD dwSize = 0;
if (!InternetQueryDataAvailable(hRequest, &dwSize, 0, 0)) {
printLastError(GetLastError());
printf("ERROR_InternetQueryDataAvailable");
return false;
}
char* responce = new char[dwSize + 1];
DWORD dwlpsizeread = 0;
if (!InternetReadFile(hRequest, responce, dwSize, &dwlpsizeread)) {
printLastError(GetLastError());
printf("ERROR_InternetReadFile");
return false;
}
printf("\nRESPONCE HEAD : \n");
SampleCodeOne(hRequest);
responce[dwSize] = 0;
std::cout << responce << std::endl;
delete[] responce;
InternetCloseHandle(hSession);
InternetCloseHandle(hConnect);
InternetCloseHandle(hRequest);
return true;
}
What am I missing? I cant seem to find the problem.
