◆ DNS_resolve_async()

bool mrpt::utils::net::DNS_resolve_async ( const std::string &  server_name,
std::string &  out_ip,
const unsigned int  timeout_ms = 3000 
)

Resolve a server address by its name, returning its IP address as a string - This method has a timeout for the maximum time to wait for the DNS server.

For example: server_name="www.google.com" -> out_ip="209.85.227.99"

Returns
true on success, false on timeout or other error.

◆ http_get() [1/2]

ERRORCODE_HTTP BASE_IMPEXP mrpt::utils::net::http_get ( const string &  url,
vector_byte out_content,
string &  out_errormsg,
int  port = 80,
const string &  auth_user = string(),
const string &  auth_pass = string(),
int *  out_http_responsecode = NULL,
mrpt::utils::TParameters< string > *  extra_headers = NULL,
mrpt::utils::TParameters< string > *  out_headers = NULL,
int  timeout_ms = 1000 
)

Perform an HTTP GET operation (version for retrieving the data as a vector_byte)

Parameters
urlMust be a simple string of the form "http://<servername>/<relative-address>".
portThe server port, if different from 80.
extra_headersIf provided, the given extra HTTP headers will be sent.
out_errormsgOn exit will contain a description of the error or "Ok".
out_contentThe buffer with the retrieved data.
out_http_responsecodeIf provided, will hold the HTTP code, eg: 200, 404...
out_headersIf provided, a copy of all the headers returned by the server will be saved here.
auth_userSend a basic HTTP authorization request with the given user & password.
auth_passSend a basic HTTP authorization request with the given user & password.
Returns
The error or success code.
