  • Upload the file in pieces, using the filesize, chunk, and offset parameters.
  • Have the MediaWiki server fetch a file from a URL, using the url parameter.
  • Complete an earlier upload that failed due to warnings, using the filekey parameter.

Note that the HTTP POST must be done as a file upload (i.e. using multipart/form-data) when sending the file.

Cargar advertencias

Note that an upload may fail due to a number of warning conditions. This can be overridden by setting ignorewarnings=1. Some notable warnings include:

  • exists: A file with the given name already exists. If this warning is ignored, the uploaded file will replace the existing file.
    • no-change: A file with the given name already exists and is exactly the same as the uploaded file.
    • duplicateversions: A file with the given name already exists and an old version of that file is exactly the same as the uploaded file.
  • was-deleted: a file with the given name used to exist but has been deleted.
  • duplicate: The uploaded file exists under a different (or the same) name. Uploading a duplicate may be undesirable.
  • duplicate-archive: The uploaded used to exist under a different (or the same) name but has been deleted. This may indicate that the file is inappropriate and should not be uploaded.
  • badfilename: The file name supplied is not acceptable on this wiki, for instance because it contains forbidden characters

Ejemplo

Hacer cualquier solicitud POST es un proceso de varios pasos:

  1. Inicia sesión, a través de uno de los métodos descritos en API:Login .
  2. GET un CSRF token .
  3. Envía una solicitud POST, con el token CSRF, para cargar un archivo.

Ejemplo 1: Cargar un archivo local directamente

Al cargar archivos directamente, la solicitud debe usar multipart/form-data como Content-Type o enctype, application/x-www-form-urlencoded no funcionará.

Ejemplo 3: Carga archivo en fragmentos

Dado que cargar un archivo enorme en una única POST HTTP puede no ser fidedigno, la API también admite un modo de carga fragmentado, donde puede realizar múltiples solicitudes con partes del archivo. Esto está disponible en MediaWiki versión 1.20 y superior, aunque antes de la versión 1.25, los SVG no se podían cargar a través de carga fragmentada. Esto es utilizado por Extensión:UploadWizard en los navegadores que admiten FileAPI, cargando archivos en fragmentos de 1 megabyte, pero puedes elegir tu propio tamaño. Esto funciona en conjunción con el modo oculto, para construir un archivo en piezas y luego cometerlo al final.

Paso 1: Pasa contenido para el primer fragmento

Para todos los fragmentos, excepto el último fragmento, recibirá esto:

Resultado 1
{
	"upload": {
		"offset": 5000,
		"result": "Continue",
		"filekey": "16gqn54g1z98.4g5brp.42588.jpg"
	}
}

Paso 2: Pasa el parámetro filekey para el segundo y más fragmentos

Obtendrás el parámetro filekey del resultado de continuación anterior también:

Para el último fragmento, recibirás esto:

Paso 3: Carga final usando filekey para cometer la carga fuera del área oculta

El resultado de la carga final incluirá el completo, objeto preciso imageinfo, comparable a lo que obtendrías de una carga no fragmentada.
