using wininet in C++ -

-

i have server if sent "https://mydomain/dir1/dir2/login.html?u=1234&t=5678" respond xml document. know how can in wininet?

here have done far:

std::string getlogindata(void) {     hinternet hinternet, hconnection, hrequest;     std::string retval;      hinternet = internetopen(l"my application", internet_open_type_direct, null, null, 0);     if(null != hinternet)     {         hconnection = internetconnect(hinternet, l"mydomain", internet_default_https_port, l"", l"", internet_service_http, 0, null);         if(null != hconnection)         {             const wchar_t* lplpszaccepttypes[] = {l"text/xml", l"application/xml", l"application/xhtml+xml", null};              hrequest = httpopenrequest(hconnection, l"get", l"dir1/dir2/login.html", null, null, lplpszaccepttypes,                 internet_flag_dont_cache | internet_flag_ignore_cert_cn_invalid | internet_flag_ignore_cert_date_invalid |                 internet_flag_ignore_redirect_to_http | internet_flag_ignore_redirect_to_https | internet_flag_keep_connection |                 internet_flag_no_auth | internet_flag_no_ui | internet_flag_pragma_nocache, 0);             if(null != hrequest)             {                 const char params[] = {"u=1234&t=5678"};                  bool rc = httpsendrequest(hrequest, null, 0, (void*)params, strlen(params));                  if(rc) // here rc = 0 , getlasterror() returns 12152                 {                     dword availdatalen;                     char buff[4096];                     dword readcount = error_internet_connection_reset;                      internetquerydataavailable(hinternet, &availdatalen, 0, 0);                     while(0 < availdatalen)                     {                         internetreadfile(hinternet, buff, min(sizeof(buff), availdatalen), &readcount);                         availdatalen -= readcount;                         retval = retval + buff;                     }                 }                 internetclosehandle(hrequest);             }             internetclosehandle(hconnection);         }         internetclosehandle(hinternet);     }     return retval; }

but can see in code httpsendrequest() fails , getlasterror() returns 12152

thank in advance sam

that's error_winhttp_invalid_server_response. best guess you're making http request on https port.

i don't know api looks need add internet_flag_secure httpopenrequest call, , / or in flags parameter of internetconnect call too:

internet_flag_secure
uses secure transaction semantics. translates using secure sockets layer/private communications technology (ssl/pct) , meaningful in http requests. flag used httpopenrequest , internetopenurl, redundant if https:// appears in url.the internetconnect function uses flag http connections; request handles created under connection inherit flag.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

fortran - Function return type mismatch -

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
