siiprop

Which file information to get:

timestamp
Adds timestamp for the uploaded version.
canonicaltitle
Adds the canonical title of the file. If the file has been revision deleted, a filehidden property will be returned.
url
Gives URL to the file and the description page. If the file has been revision deleted, a filehidden property will be returned.
size
Adds the size of the file in bytes and the height, width and page count (if applicable).
dimensions
Alias for size.
sha1
Adds SHA-1 hash for the file. If the file has been revision deleted, a filehidden property will be returned.
mime
Adds MIME type of the file. If the file has been revision deleted, a filehidden property will be returned.
thumbmime
Adds MIME type of the image thumbnail (requires url and param siiurlwidth). If the file has been revision deleted, a filehidden property will be returned.
metadata
Lists Exif metadata for the version of the file. If the file has been revision deleted, a filehidden property will be returned.
commonmetadata
Lists file format generic metadata for the version of the file. If the file has been revision deleted, a filehidden property will be returned.
extmetadata
Lists formatted metadata combined from multiple sources. Results are HTML formatted. If the file has been revision deleted, a filehidden property will be returned.
bitdepth
Adds the bit depth of the version. If the file has been revision deleted, a filehidden property will be returned.
badfile
Adds whether the file is on the MediaWiki:Bad image list
Values (separate with | or alternative): badfile, bitdepth, canonicaltitle, commonmetadata, dimensions, extmetadata, metadata, mime, sha1, size, thumbmime, timestamp, url
Default: timestamp|url
siiurlwidth

If siiprop=url is set, a URL to an image scaled to this width will be returned.

For performance reasons if this option is used, no more than 50 scaled images will be returned.

Type: integer
Default: -1
siiurlheight

Similar to siiurlwidth.

Type: integer
Default: -1
siiurlparam

A handler specific parameter string. For example, PDFs might use page15-100px. siiurlwidth must be used and be consistent with siiurlparam.

Default: (empty)


示例

发出任何POST请求都是一个多步骤的过程:

  1. 使用API:登录 中描述的方法之一登录。
  2. API:令牌 所示,取得(GET)編輯/CSRF令牌
  3. 发送带有CSRF令牌的POST请求以在页面上执行操作。

下面的示例代碼涵蓋了這些步驟。

可能的错误

代码 信息
notloggedin 上传暂存功能只对已登录用户可用。
stashedfilenotfound 无法在暂存处找到文件:key
stashpathinvalid 文件密钥的格式不正确,或属于其他无效格式:key
uploadstash-bad-path-bad-format 键“#####”的格式不正确。

参数历史

  • v1.23: 启用canonicaltitle, commonmetadata, extmetadata
  • v1.18: 启用siifilekey, siiurlparam
  • v1.18: 弃用siisessionkey

附加提醒

  • 尽管它出现在自己的stashimageinfo键下,而不像其他属性模块那样出现在pages键下,但该模块的输出与API:Imageinfo 的输出相同。
