本文整理匯總了TypeScript中mime.extension函數的典型用法代碼示例。如果您正苦於以下問題：TypeScript extension函數的具體用法？TypeScript extension怎麽用？TypeScript extension使用的例子？那麽, 這裏精選的函數代碼示例或許可以為您提供幫助。
在下文中一共展示了extension函數的4個代碼示例，這些例子默認根據受歡迎程度排序。您可以為喜歡或者感覺有用的代碼點讚，您的評價將有助於係統推薦出更棒的TypeScript代碼示例。
示例1: GetFilenameForMediaEvent
private GetFilenameForMediaEvent(content: IMatrixEventContent): string {
if (content.body) {
if (path.extname(content.body) !== "") {
return content.body;
}
return `${path.basename(content.body)}.${mime.extension(content.info.mimetype)}`;
}
return "matrix-media." + mime.extension(content.info.mimetype);
}示例2:
import * as mime from "mime";
let str: string;
const obj: {} = {};
const fallback = '';
str = mime.lookup(str, fallback);
str = mime.extension(str);
mime.load(str);
mime.define(obj);
str = mime.charsets.lookup(str);
示例3: function
filename: function (req, file, cb) {
cb(null, file.fieldname + '-' + Date.now() + '.' + mime.extension(file.mimetype))
