Sure, I can help you with that. Can you please provide more details about the type of file you want to upload and the server you want to upload it to? Also, do you have any specific requirements for the Indy library version or programming language?How to prepare POST request to upload file using Indy library?
Great, here is an example of how to prepare a POST request to upload a file to VirusTotal using Indy library in C++:File of binary type. Language: C++. Server is virustotal.com
c++
#include <iostream>
#include <string>
#include <memory>
#include <IdHTTP.hpp>
#include <IdMultipartFormData.hpp>
#include <IdSSLOpenSSL.hpp>
int main() {
// Set up Indy components
std::unique_ptr<TIdHTTP> http(new TIdHTTP());
std::unique_ptr<TIdSSLIOHandlerSocketOpenSSL> ssl(new TIdSSLIOHandlerSocketOpenSSL());
http->IOHandler = ssl.get();
// Set up SSL options
ssl->SSLOptions->SSLVersions = TIdSSLVersions() << sslvTLSv1_2;
ssl->SSLOptions->Method = sslvTLSv1_2;
ssl->SSLOptions->Mode = sslmClient;
// Set up the request
std::unique_ptr<TIdMultipartFormDataStream> request(new TIdMultipartFormDataStream());
request->AddFormField("apikey", "YOUR_API_KEY_HERE");
request->AddFile("file", "C:\\path\\to\\your\\file.bin", "application/octet-stream");
// Send the request
try {
std::unique_ptr<TMemoryStream> response(new TMemoryStream());
http->Post("https://www.virustotal.com/vtapi/v2/file/upload", request.get(), response.get());
std::cout << response->Size << " bytes received." << std::endl;
}
catch (const Exception& e) {
std::cerr << "Error: " << e.Message.c_str() << std::endl;
}
return 0;
}
You can use theHow can I specify proxy settings to be used from the one defined in Internet Explorer settings?
TIdProxyTransparent
component in Indy to automatically use the proxy settings defined in Internet Explorer. Here is an example of how to set it up in C++:c++
#include <iostream>
#include <memory>
#include <IdHTTP.hpp>
#include <IdSSLOpenSSL.hpp>
#include <IdIOHandlerStack.hpp>
#include <IdIOHandlerSocket.hpp>
#include <IdIOHandlerStack.hpp>
#include <IdIOHandler.hpp>
#include <IdProxyTransparent.hpp>
int main() {
// Set up Indy components
std::unique_ptr<TIdHTTP> http(new TIdHTTP());
std::unique_ptr<TIdSSLIOHandlerSocketOpenSSL> ssl(new TIdSSLIOHandlerSocketOpenSSL());
std::unique_ptr<TIdIOHandlerStack> ioStack(new TIdIOHandlerStack());
// Set up SSL options
ssl->SSLOptions->SSLVersions = TIdSSLVersions() << sslvTLSv1_2;
ssl->SSLOptions->Method = sslvTLSv1_2;
ssl->SSLOptions->Mode = sslmClient;
// Set up transparent proxy
std::unique_ptr<TIdProxyTransparent> proxy(new TIdProxyTransparent());
proxy->Enabled = true;
ioStack->TransparentProxy = proxy.get();
// Set up IO handlers
ioStack->Intercept = ssl.get();
ioStack->ConnectTimeout = 5000;
http->IOHandler = ioStack.get();
// Send the request
try {
std::unique_ptr<TMemoryStream> response(new TMemoryStream());
http->Get("https://www.google.com", response.get());
std::cout << response->Size << " bytes received." << std::endl;
}
catch (const Exception& e) {
std::cerr << "Error: " << e.Message.c_str() << std::endl;
}
return 0;
}
I apologize for the confusion. TheI can't find IdProxyTransparent.hpp
TIdProxyTransparent
component is not available in the current version of Indy (version 10.6.2.0). TIdConnectThroughHttpProxy
component to achieve the same result. Here is an example of how to set it up in C++:c++
#include <iostream>
#include <memory>
#include <IdHTTP.hpp>
#include <IdSSLOpenSSL.hpp>
#include <IdIOHandlerStack.hpp>
#include <IdIOHandlerSocket.hpp>
#include <IdIOHandlerStack.hpp>
#include <IdIOHandler.hpp>
#include <IdConnectThroughHttpProxy.hpp>
int main() {
// Set up Indy components
std::unique_ptr<TIdHTTP> http(new TIdHTTP());
std::unique_ptr<TIdSSLIOHandlerSocketOpenSSL> ssl(new TIdSSLIOHandlerSocketOpenSSL());
std::unique_ptr<TIdIOHandlerStack> ioStack(new TIdIOHandlerStack());
// Set up SSL options
ssl->SSLOptions->SSLVersions = TIdSSLVersions() << sslvTLSv1_2;
ssl->SSLOptions->Method = sslvTLSv1_2;
ssl->SSLOptions->Mode = sslmClient;
// Set up proxy
std::unique_ptr<TIdConnectThroughHttpProxy> proxy(new TIdConnectThroughHttpProxy());
proxy->Enabled = true;
ioStack->TransparentProxy = proxy.get();
// Set up IO handlers
ioStack->Intercept = ssl.get();
ioStack->ConnectTimeout = 5000;
http->IOHandler = ioStack.get();
// Send the request
try {
std::unique_ptr<TMemoryStream> response(new TMemoryStream());
http->Get("https://www.google.com", response.get());
std::cout << response->Size << " bytes received." << std::endl;
}
catch (const Exception& e) {
std::cerr << "Error: " << e.Message.c_str() << std::endl;
}
return 0;
}
ioStack->Intercept = ssl.get();
I apologize for the mistake. The correct way to set up the SSL interceptor is to use theCompiler throws an error in this line:
cannot initialize a parameter of type 'Idintercept::TIdConnectionIntercept *' with an rvalue of type 'pointer' (aka 'Idsslopenssl::TIdSSLIOHandlerSocketOpenSSL *')Код:ioStack->Intercept = ssl.get();
TIdSSLIOHandlerSocketOpenSSL
component as the IOHandler for the TIdIOHandlerStack
