暫時(shí)我還沒(méi)有把這個(gè)做成一個(gè)插件，只是簡(jiǎn)單的幾行代碼。其中原理就是通過(guò)截圖后，ev.clipboardData 包含了text和圖片文件 數(shù)據(jù)

這是一個(gè)完整的示例，其中

$("#post_content") 便是監(jiān)聽(tīng)paste事件

public function upEditorImg()
    {
        $token = Session::get("user_token");
        if (!$token || $token["id"] <= 0) {
            $this->error("對(duì)不起,您沒(méi)有權(quán)限操作");
        }
        // 獲取表單上傳文件 例如上傳了001.jpg
        $base64 = input("base");
        $savePath = Config::get("storage_path.editor");
        $file = Utils::saveBase642Img($base64, $savePath);
        if (!$file) {
            $this->result([], 500, "上傳失敗,請(qǐng)檢查上傳文件");
        }
        // 移動(dòng)到框架應(yīng)用根目錄/public/uploads/ 目錄下

        if ($file->check(["size" => 1024 * 1024 * 1, "ext" => "jpg,png,jpeg,gif"])) {
            $entity = [
                "create_time" => time(),
                "title" => $file->getInfo("name"),
                "size" => $file->getInfo("size"),
                "ext" => $file->getExtension(),
                "type" => $file->getInfo("type"),
                "path" => "/upload/editor" . $file->getInfo("build_path"),
                "md5" => $file->md5(),
                "uid" => $token["id"],
            ];
            $pic = new BbsPicture();
            $ret = $pic->insertGetId($entity);
            if (!$ret) {
                $this->result([], 500, "上傳失敗,請(qǐng)稍后重試");
            }
            $entity["title"] = "screenshots.{$entity["ext"]}";
            $this->result($entity, 1, "上傳成功", "Json");
        } else {
            $this->result([], 0, $file->getError(), "Json");
        }
    }

PHP使用了ThinkPHP框架，其中Utils是個(gè)人封裝的一個(gè)base64得

    /**
     * @param $content
     * @param $path
     * @return bool|File
     */
    static public function saveBase642Img($content, $path)
    {
        if (preg_match("/^(data:s*image/(w+);base64,)/", $content, $result)) {
            $type = $result[2];
            $file["type"] = "images/" . $type;
            $file["ext"] = $type;
            $file["save_path"] = $path . DS . date("Ymd") . DS;
            if (!is_dir($file["save_path"])) {
                mkdir($file["save_path"], 0777);
            }
            $file["data"] = base64_decode(str_replace($result[1], "", $content));
            $file["name"] = md5($file["data"]) . ".{$file["ext"]}";
            if (!file_put_contents($file["save_path"] . $file["name"], $file["data"])) {
                return false;
            }
            unset($file["data"]);
            $FILE = new File($file["save_path"] . $file["name"]);
            $file["size"] = $FILE->getSize();
            $file["saveName"] = $file["save_path"] . $file["name"];
            $file["build_path"] = DS . date("Ymd") . DS . $file["name"];

            $FILE->setUploadInfo($file);
            return $FILE;
        } else {
            return false;
