I am looking for curl aternative to Wininet InternetCrackUrl.
if not curl any function which splits the url will work .
Pointers around this would be helpful.
You are looking for the functions from urlapi.h, just add #include <curl/urlapi.h>. cURL is more object-oriented than Win32 API. You create URL object on the first step and then you can manipulate URL parts.
char *path = NULL;
CURLU *url = curl_url();
curl_url_set(url, CURLUPART_URL, "https://example.com/path/to/file", 0);
curl_url_get(url, CURLUPART_HOST, &path, CURLU_URLDECODE);
curl_url_cleanup(url);
The above example is equivalent of
char *path = NULL;
LPURL_COMPONENTS parts = {0};
InternetCrackUrl("https://example.com/path/to/file", 0, ICU_DECODE, &parts);
path = parts.lpszUrlPath;

I'm trying to follow this example to let me make a POST request to a web server and receive its response in pure C++ using Core Foundation functions. I'll copy and paste it here:
void PostRequest()
{
// Create the POST request payload.
CFStringRef payloadString = CFStringCreateWithFormat(kCFAllocatorDefault, NULL, CFSTR("{\"test-data-key\" : \"test-data-value\"}"));
CFDataRef payloadData = CFStringCreateExternalRepresentation(kCFAllocatorDefault, payloadString, kCFStringEncodingUTF8, 0);
CFRelease(payloadString);
//create request
CFURLRef theURL = CFURLCreateWithString(kCFAllocatorDefault, CFSTR("https://httpbin.org/post"), NULL); //https://httpbin.org/post returns post data
CFHTTPMessageRef request = CFHTTPMessageCreateRequest(kCFAllocatorDefault, CFSTR("POST"), theURL, kCFHTTPVersion1_1);
CFHTTPMessageSetBody(request, payloadData);
//add some headers
CFStringRef hostString = CFURLCopyHostName(theURL);
CFHTTPMessageSetHeaderFieldValue(request, CFSTR("HOST"), hostString);
CFRelease(hostString);
CFRelease(theURL);
if (payloadData)
{
CFStringRef lengthString = CFStringCreateWithFormat(kCFAllocatorDefault, NULL, CFSTR("%ld"), CFDataGetLength(payloadData));
CFHTTPMessageSetHeaderFieldValue(request, CFSTR("Content-Length"), lengthString);
CFRelease(lengthString);
}
CFHTTPMessageSetHeaderFieldValue(request, CFSTR("Content-Type"), CFSTR("charset=utf-8"));
//create read stream for response
CFReadStreamRef requestStream = CFReadStreamCreateForHTTPRequest(kCFAllocatorDefault, request);
CFRelease(request);
//set up on separate runloop (with own thread) to avoid blocking the UI
CFReadStreamScheduleWithRunLoop(requestStream, CFRunLoopGetCurrent(), kCFRunLoopCommonModes);
CFOptionFlags optionFlags = (kCFStreamEventHasBytesAvailable | kCFStreamEventErrorOccurred | kCFStreamEventEndEncountered);
CFStreamClientContext clientContext = {0, (void *)payloadData, RetainSocketStreamHandle, ReleaseSocketStreamHandle, NULL};
CFReadStreamSetClient(requestStream, optionFlags, ReadStreamCallBack, &clientContext);
//start request
CFReadStreamOpen(requestStream);
if (payloadData)
{
CFRelease(payloadData);
}
}
And the callback:
void LogData(CFDataRef responseData)
{
CFIndex dataLength = CFDataGetLength(responseData);
UInt8 *bytes = (UInt8 *)malloc(dataLength);
CFDataGetBytes(responseData, CFRangeMake(0, CFDataGetLength(responseData)), bytes);
CFStringRef responseString = CFStringCreateWithBytes(kCFAllocatorDefault, bytes, dataLength, kCFStringEncodingUTF8, TRUE);
CFShow(responseString);
CFRelease(responseString);
free(bytes);
}
static void ReadStreamCallBack(CFReadStreamRef readStream, CFStreamEventType type, void *clientCallBackInfo)
{
CFDataRef passedInData = (CFDataRef)(clientCallBackInfo);
CFShow(CFSTR("Passed In Data:"));
LogData(passedInData);
//append data as we receive it
CFMutableDataRef responseBytes = CFDataCreateMutable(kCFAllocatorDefault, 0);
CFIndex numberOfBytesRead = 0;
do
{
UInt8 buf[1024];
numberOfBytesRead = CFReadStreamRead(readStream, buf, sizeof(buf));
if (numberOfBytesRead > 0)
{
CFDataAppendBytes(responseBytes, buf, numberOfBytesRead);
}
} while (numberOfBytesRead > 0);
//once all data is appended, package it all together - create a response from the response headers, and add the data received.
//note: just having the data received is not enough, you need to finish the response by retrieving the response headers here...
CFHTTPMessageRef response = (CFHTTPMessageRef)CFReadStreamCopyProperty(readStream, kCFStreamPropertyHTTPResponseHeader);
if (responseBytes)
{
if (response)
{
CFHTTPMessageSetBody(response, responseBytes);
}
CFRelease(responseBytes);
}
//close and cleanup
CFReadStreamClose(readStream);
CFReadStreamUnscheduleFromRunLoop(readStream, CFRunLoopGetCurrent(), kCFRunLoopCommonModes);
CFRelease(readStream);
//just keep the response body and release requests
CFDataRef responseBodyData = CFHTTPMessageCopyBody(response);
if (response)
{
CFRelease(response);
}
//get the response as a string
if (responseBodyData)
{
CFShow(CFSTR("\nResponse Data:"));
LogData(responseBodyData);
CFRelease(responseBodyData);
}
}
I understood how it works, and started implementing it ..... only to get this error:
'CFReadStreamCreateForHTTPRequest' is deprecated: first deprecated in
macOS 10.11 - Use NSURLSession API for http requests
There's absolutely zero examples how to use NSURLSession for C++, or how to bypass that idiotic "is deprecated" error.
Any help on how am I supposed to code this in C++ now?
PS. I don't want to use any third-party libraries. This is a simple task that was available with simple API calls (as I showed above.)
PS2. Sorry I am not an Apple developer, and I'm not used to features being deprecated on the whim.
There are 3 options.
Ignore the warning.
Use ObjC runtme.
Use libcurl
The first one is the easiest and the second one is the hardest solutions for your skills. The third option is easy and the most advanced solution - if you extend you software with new features, CFNetwork will lack of functionality.
I am trying to figure out how to check if a user has a valid password with LDAP c++ code. This seems maddeningly difficult for what seems to be it's intended purpose.
The only working example code I could find was ldapsearch. I can log in as the default user and search for the user:
ldapsearch -x -D "cn=ldap,cn=Users,dc=company,dc=local" -W -H ldap://localhost:389 -b "ou=company_account,dc=company,dc=local" -s sub 'uid=my_id'
This seems to correspond to this code (note: lots of error checking removed)
LDAP *ld = NULL;
string sHostIP = session.ini["ldap_host"];
string sPort = session.ini["ldap_port"];
string sURL = sHostIP+":"+sPort;
ldap_initialize( &ld, sURL.c_str() );
int iVersion = LDAP_VERSION3;
ldap_set_option( ld, LDAP_OPT_PROTOCOL_VERSION, &iVersion );
string sLDAPPW = session.ini["ldap_server_pw"];
struct berval pServerPassword = { 0, NULL };
pServerPassword.bv_val = ber_strdup( &sLDAPPW[0] );
pServerPassword.bv_len = strlen( pServerPassword.bv_val );
//can't bind without this code block, but what does it even do?
int iMsgid;
int nsctrls = 0;
LDAPControl c;
c.ldctl_oid = LDAP_CONTROL_PASSWORDPOLICYREQUEST;
c.ldctl_value.bv_val = NULL;
c.ldctl_value.bv_len = 0;
c.ldctl_iscritical = 0;
LDAPControl sctrl[3];
sctrl[nsctrls] = c;
LDAPControl *sctrls[4];
sctrls[nsctrls] = &sctrl[nsctrls];
sctrls[++nsctrls] = NULL;
LDAPControl **sctrlsp = NULL;
if ( nsctrls )
{
sctrlsp = sctrls;
}
KString sBindDN = session.ini["ldap_bind_dn"];
ldap_sasl_bind( ld, sBindDN.c_str(), LDAP_SASL_SIMPLE, &pServerPassword,sctrlsp, NULL, &iMsgid );
This is where, if we kept the hashed userPassword value I could search for a uid and userPassword combination. but since my company doesn't keep userPassword, that won't work.
I'm told that the other way to check the password is to bind as the user with the user password. But I need to use a different DN so I'm binding as user? Or I log in as the admin first then do a second bind as the user? And apparently this code is depreciated, but every non-depreciated example code I try to build crashes? Is there something I'm missing? Is there a good working example I use to authenticate users? I know apache can authenticate off of this LDAP server, but I don't know how.
Apache ldap.conf info here:
AuthLDAPURL "ldap://localhost:389/ou=company_account,dc=company,dc=local?sAMAccountName?sub?(objectClass=*)"
AuthLDAPBindDN "cn=ldap,cn=Users,dc=company,dc=local"
AuthLDAPBindPassword "removed"
you need just to perform ldap bind or sasl_bind
void TLDAP::sasl_simple_bind(const std::string & ldapDn, const std::string & ldapPw)
{
struct berval c_passwd = { 0, 0 };
c_passwd.bv_val = const_cast<char*>(ldapPw.c_str());
c_passwd.bv_len = ldapPw.size();
Check(ldap_sasl_bind_s(l.get(), ldapDn.c_str(), LDAP_SASL_SIMPLE, &c_passwd, NULL, NULL, NULL));
}
void TLDAP::simple_bind(const std::string & ldapDn, const std::string & ldapPw)
{
Check(ldap_simple_bind_s(l.get(), ldapDn.c_str(), ldapPw.c_str()));
}
ldap_simple_bind for non-encrypted connection, sasl_bind for encrypted
invocation example:
TLDAP::sasl_simple_bind("andrey#mydomain.local", "1234asdf%^^&");
function Check just checks the return value and throws exception
I have my xml as char buffer (that's fetched from server, I don't want to save it -> takes extra time and is completely obsolete):
char myword[] = "...xml..."
xmlSchemaParserCtxtPtr ctxt = xmlSchemaNewParserCtxt(xsdFilePath);
xmlDocPtr doc = ?;
Now I need to get doc. I'm trying to use following function:
doc = xmlReadMemory(myword, sizeof(myword), ?URL?, NULL, 0)
But the problem is with URL, what should I put in there..? Am I using this function right? Maybe there is another way to get xmlDocPtr?
BTW: I need xmlDocPtr to perform:
ret = xmlSchemaValidateDoc(ctxt, doc);
Simply pass a NULL pointer:
doc = xmlReadMemory(myword, sizeof(myword), NULL, NULL, 0);

I can connect my microsoft web service and I can insert record with this service easily.
I get a confirmation code as a response for record insert. But I have a problem with encoding. The response message must like this 1Exa9GwOIO6pP35l4TJ1Bw== but instead of this I get a response like this 4�� u #
When I try this service on a browser I get the expected response as
in 1Exa9GwOIO6pP35l4TJ1Bw==
But when I try it on an android device with gsoap I get a response such as this one 4�� u #
How can I solve this encoding problem?
TheGameSoapProxy service;
_ns1__PlayerRegisterResponse* response = new _ns1__PlayerRegisterResponse();
std::string telNO =m_pEditTel->getText();
std::string telefonIME = "111";
std::string simCardID = "222";
std::string Username = m_pEditName->getText();
std::string takim = Takim.c_str();
_ns1__PlayerRegister* ps = new _ns1__PlayerRegister();
ps->telefonNumarasi = &telNO;
ps->telefonIME = &telefonIME;
ps->simCardID = &simCardID;
ps->Username = &Username;
ps->takim = &takim;
if (service.PlayerRegister(ps, response) == SOAP_OK)
{
string *ptrSonuc = response->PlayerRegisterResult;
CCLog( (char*)ptrSonuc );
}
As per other question here on SO:
add the line below to your typemap.dat file:
xsd__string = | wchar_t* | wchar_t*
And then use wstrings instead of strings.
I'm working on a C++ program that will automatically backup my work to my FTP server. So far I am able to upload a single file, by specifying a file name using this
CString strFilePath = szFile ;
int iPos = strFilePath.ReverseFind('\\');
CString strFileName = strFilePath.Right((strFilePath.GetLength()- iPos-1) );
CString strDirPath = m_szFolderDroppedIn ;
strDirPath = strDirPath.Mid(0,strDirPath.GetLength() - 1);
int iPost = strDirPath.ReverseFind('\\');
CString strDirName = strDirPath.Right((strDirPath.GetLength()- iPost -1) );
bool curdir = ftpclient.SetServerDirectory((char*)strDirName.GetBuffer(strDirName.GetLength()));
//Upload to Server
int uploadret = ftpclient.PutFile(szFile,(char*)strFileName.GetBuffer(strFileName.GetLength()),0,true,dwLastError);
m_lsDroppedFiles.RemoveAll();
break;
}
Now I want to be able to iterate through a directory (Which contains subdirectories) and recursively call. I'm having a problem getting a hold of the files in the directory.
Any help or code snippet...
Since you are using MFC, you can use the CFileFind class. Example code is given in MSDN. Alternatively, you can use boost.filesystem for the same.
#Swapnil: If you use boost::filesystem, there is a recursive_directory_iterator
