.net - Send custom header for all WCF REST OPTION calls -

-

i'm trying implement standalone wcf rest service. 1 problem have have send custom objects, webget can't handle. i'm trying send them post instead of get.

now of course can't make jsonp request post data. work around this, have send allow-origin header calls made "options" http-method. there

  • a way apply header each option call?
  • a way intercept , allow option-calls without setting [webrequest(method = "*")](instead of [webrequest(method = "post")]
  • a way add headers , return request without calling wcf method?

or alternatively, how can override parameter-serialization method of webget?

i tried solve custom endpoints , messagedispatchers, doesn't seem work.

i figured out how overwrite parameter serialization of webget. this question pointed me in right direction.

i had overwrite httpbehavior , add own querystringconverter, uses newtonsoft json serializer.

     public class customquerystringconverter :system.servicemodel.dispatcher.querystringconverter         {             public override bool canconvert(type type)             {                 return true;             }              public override object convertstringtovalue(string parameter, type parametertype)             {                 if (base.canconvert(parametertype))                 {                     return base.convertstringtovalue(parameter, parametertype);                 }                 else                 {                     object param = newtonsoft.json.jsonconvert.deserializeobject(parameter, parametertype);                     return param;                 }             }              public override string convertvaluetostring(object parameter, type parametertype)             {                 if (base.canconvert(parametertype))                 {                     return base.convertvaluetostring(parameter, parametertype);                 }                 else                 {                     return newtonsoft.json.jsonconvert.serializeobject(parameter);                 }             }         }

this removes need sending options headers , post data.

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...
