PHP & C++ $_FILES 和 HttpSendRequestA

将文件从c++上传到PHP表单时遇到问题。Iv看到了与我的问题类似的帖子。

• 用C上传图像文件++
• 使用C++HTTP请求将文件上载到服务器

根据每个和HERE中列出的文档，所有帐户的代码都应该是正确的。

我也不能将CURL用于我的实现。我也愿意。

Iv尝试将所有数据编码到BASE64中，以缓解任何文件数据问题，但没有成功。

Iv仔细检查了我的php.ini文件以允许上传。并用一个简单的HTML页面测试了PHP页面，该页面允许我上传文件。一切都很好，表格给出了正确的结果。

基本上，我发送到服务器的标题是：

Host: dzwxgames.com
Connection: close
Content-Length: 418
Origin: http://dzwxgames.com
Content-Type: multipart/form-data; boundary=WrbKitFormBoundaryXtRo8bh7ZpnTrTwd

--WrbKitFormBoundaryXtRo8bh7ZpnTrTwd--

我的PHP页面返回的内容：

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.

php页面的代码很简单：

if (!isset($_FILES['file']['error'])){
var_dump($_FILES['file']);
print_r($_FILES);
throw new RuntimeException('File does not exist.');
}

最后我的C++代码是：

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 += "--WrbKitFormBoundaryXtRo8bh7ZpnTrTwdrn";
datahead += "Content-Disposition: form-data; name="file"; filename="" + file.filename().string() +""rn";  //Content - Disposition : form - data; name = "fileToUpload"; filename = "testMac.cpp"
datahead += "Content-Type: text/plain;rn";
datahead += "Content-Transfer-Encoding: BASE64rnn";
datahead += content;
datahead += "rn--WrbKitFormBoundaryXtRo8bh7ZpnTrTwd--rn";
//datahead = base64_encode(reinterpret_cast<const unsigned char*>(datahead.c_str()), datahead.length());
//Build Headder
headder += "Host: " + iaddr + "rn";                                       //Host: localhost
headder += "Connection: closern";                                         //Connection : keep - alive
headder += "Content-Length: " + std::to_string(datahead.size()) + "rn";   //Content - Length : 800
headder += "Origin: http://dzwxgames.comrn";
//headder += "Content-Transfer-Encoding: base64rn";
headder += "Content-Type: multipart/form-data; boundary=WrbKitFormBoundaryXtRo8bh7ZpnTrTwdrn";    //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/537.36rn";                                            //User - Agent: 1337
headder += "Pragma: no-cachernrn";                                     
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;
}

我错过了什么？我似乎找不出问题。
