Enviar por POST a webservice
Posted: Thu Jan 06, 2022 12:21 pmEstimados:
Estoy intentando crear una clase para poder subir datos a un especie de webservice mediante POST
Digo "una especie" porque el "webservice" lo estoy haciendo yo.
Aclaro que no soy experto en ninguna de las dos cosas.
El tema es que funciona bien todo, EXCEPTO como graba la imagen en el servidor.
Los datos de campos y fichero de texto plano (el .prg) está siendo enviado bien y lo puedo ver perfectamente en el servidor
Pero la imagen no es leíble (también me paso con un archivo zip). Intuyo que debe ser la codificación pero no le encuentro la vuelta
Dejo el código por si algún experto me puede dar una mano.
La clase es esta:
Agradezco cualquier sugerencia
