Hi! I'm trying to turn a (working) command-line call to curl into an equivalent c++ program.
The following command line I was able to translate into c++ curl --location --request POST 'https://servername.domain/token' \ --header 'Content-Type: application/x-www-form-urlencoded' \ --data-urlencode 'client_id=ie_client' \ --data-urlencode 'client_secret=*secret_code*' \ --data-urlencode 'grant_type=client_credentials' 2>/dev/null Translated to c++, this became bool getToken( std::string & token ) { CURL * curl; CURLcode res; std::string json_record; curl = curl_easy_init(); if ( curl ) { curl_easy_setopt( curl, CURLOPT_URL, " https://servername.domain/token"; ); curl_easy_setopt( curl, CURLOPT_HEADER, "Content-Type: application/x-www-form-urlencoded" ); curl_easy_setopt( curl, CURLOPT_POST, 1L ); curl_easy_setopt( curl, CURLOPT_WRITEFUNCTION, token_callback ); curl_easy_setopt( curl, CURLOPT_WRITEDATA, &json_record ); curl_easy_setopt( curl, CURLOPT_POSTFIELDS, "client_id=ie_client&client_secret=*secret_code*&grant_type=client_credentials" ); res = curl_easy_perform( curl ); curl_easy_cleanup( curl ); if( CURLE_OK != res ) { fprintf( stderr, "curl_easy_perform() failed: %s\n", curl_easy_strerror( res )); return false; } } if ( ! json_record.empty() ) { return true; } return false; } The function retrieves data, from which I am able to extract the token. But it is the second part, using the token that I haven't been able to translate. The (working) command-line for that is curl --location --request POST https://otherserver.domain/command/nodename?commandId=get-some-data\&mode=sync --header "Authorization: Bearer *token_retrieved_by_previous_command_line*" The command-line functions and retrieves the data, no problem. However, the following code always returns an error message from the server bool ExecuteCommand( const char * token ) { CURL * curl; CURLcode res; std::string json_record; curl = curl_easy_init(); if ( curl ) { curl_easy_setopt( curl, CURLOPT_URL, " https://otherserver.domain/command/nodename"; ); curl_easy_setopt( curl, CURLOPT_HEADER, ( ( (std::string)"Authorization: Bearer" ) + token ).c_str() ); curl_easy_setopt( curl, CURLOPT_POST, 1L ); curl_easy_setopt( curl, CURLOPT_FOLLOWLOCATION, 1L ); curl_easy_setopt( curl, CURLOPT_POSTFIELDS, "commandId=get-some-data&mode=sync" ); res = curl_easy_perform( curl ); curl_easy_cleanup( curl ); if( CURLE_OK != res ) { fprintf( stderr, "curl_easy_perform() failed: %s\n", curl_easy_strerror( res )); return false; } } return true; } Although the curl_easy_perform call does succeed, the data returned is not what is expected, it returns *{"error-code":"Internal Error","error-message":"Content type 'application/x-www-form-urlencoded' not supported","request-id":""}* What am I doing wrong? Thank you for any help
