Requête POST pour téléverser un fichier.

Il existe trois méthodes pour téléverser des fichiers via l'API :

  1. Téléverser un fichier local directement
  2. Téléverser une copie d'un fichier à partir d'une URL
  3. Téléverser un fichier local par parties

Toutes ces méthodes imposent que le compte a les droits upload.

Upload a file, or get the status of pending uploads.

Several methods are available:

  • Upload file contents directly, using the file parameter.
  • 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.

Specific parameters:
Other general parameters are available.

Type: boolean (details)
filesize

Filesize of entire upload.

Type: integer
The value must be between 0 and 5,368,709,120.

Avertissements de téléversement

Notez qu'un téléversement peut échouer en raison d'un certain nombre de conditions d'avertissement. Vous pouvez remplacer ce paramètre en définissant ignorewarnings=1. Voici quelques avertissements notables :

  • exists: Un fichier portant le nom donné existe déjà. Si cet avertissement est ignoré, le fichier téléversé remplacera le fichier existant.
    • no-change: Un fichier avec le nom donné existe déjà; il est exactement le même que le fichier téléversé.
    • duplicateversions: Un fichier avec le nom donné existe déjà et l'ancienne version de ce fichier est exactement la même que le fichier téléversé.
  • was-deleted: un fichier avec le nom donné a déjà existé par le passé mais a été supprimé.
  • duplicate: Le fichier téléversé existe sous un nom différent (ou identique). Le téléversement d'un doublon peut être non souhaité.
  • duplicate-archive: Le fichier téléversé existait sous un nom différent (ou identique) mais a été supprimé. Cela peut indiquer que le fichier est inapproprié et ne doit pas être téléversé.
  • badfilename: The file name supplied is not acceptable on this wiki, for instance because it contains forbidden characters
Result
{
  "upload": {
    "result": "Warning",
    "warnings": {
      "badfilename": "My_bad:filename.png"

    "sessionkey": "19mmz8arzreg.9md1cj.2283740.png"
  }
}


Exemple

Faire une requête POST donnée est un processus en plusieurs étapes :

  1. Connectez-vous via l'une des méthodes décrites dans API:Authentification .
  2. Obtenir un CSRF token :
  3. Envoyez une demande POST, avec le jeton CSRF pour téléverser un fichier.

Exemple n°1 : téléverser directement un fichier local

Lorsque vous téléversez des fichiers directement, la requête doit utiliser multipart/form-data en tant que Content-Type ou enctype, application/x-www-form-urlencoded ne fonctionnera pas.

Exemple n°3 : téléverser un fichier par parties

Comme le téléversement d'un gros fichier avec un seul HTTP POST peut devenir peu fiable, l'API prend également en charge un mode de téléversement segmenté, où vous effectuez plusieurs demandes contenant les parties successives du fichier. Ceci est disponible dans MediaWiki version 1.20 et supérieure, bien qu'avant la version 1.25, les SVG ne pouvaient pas être téléversés via le téléchargement groupé. Cela est utilisé par Extension:UploadWizard/fr dans les navigateurs prenant en charge FileAPI, téléchargeant des fichiers en morceaux de 1 mégaoctet, mais vous pouvez choisir votre propre taille. Cela fonctionne en conjonction avec le mode stash, pour construire un fichier par morceaux et ensuite le valider à la fin.

Étape n°1 : transmettre le contenu pour la première partie

Pour tous les morceaux sauf le dernier morceau, vous recevrez ceci :

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

Étape n°2 : passer le paramètre filekey pour les morceaux suivants

Vous obtiendrez également le paramètre filekey à partir du précédent résultat continue :

Pour le dernier morceau, vous recevrez ceci :
