如何使用Laravel在MySQL中插入表情符号？

Question

我的MySQL数据库排序规则是：utf8mb4_unicode_ci如下所示：

但是，当我尝试使用Laravel将其插入表中时，它会引发以下错误：

SQLSTATE[22007]: Invalid datetime format: 1366 Incorrect string value: '\xF0\x9F\x98\x89' for column `challenges`.`challenges`.`description` at row 1 (SQL: insert into `challenges` (`hashtag`, `title`, `description`, `challenge_id`, `image_name`, `category_id`, `duration`, `link`, `user_id`, `updated_at`, `created_at`) values (emojiasd, Emoji Test, Hey this is an emoji 😉, 5edccab9327c4, challenge-55edccab9327e81591528121.png, 2, 0, ?, 5ec443a71e40b, 2020-06-07 11:08:41, 2020-06-07 11:08:41))

这是我控制器中的存储方法：

public function store(Request $request)
    {
        //
        $this->validate($request, [
            'hashtag' => 'required',
            'title' => 'required',
            'description' => 'required',
            'category' => 'required',
            'image' => 'required|image|mimes:jpeg,png,jpg|max:2048',
            'duration' => 'required'
        ]);

        $challenge = new Challenge;
        $replace = array (' ', '#');
        $challenge->hashtag = strtolower(str_replace($replace, '', $request->input('hashtag')));
        $challenge->title = $request->input('title');
        $challenge->description = $request->input('description');
        $challenge->challenge_id = uniqid();

        $image = $request->file('image');
        $imageName = 'challenge-' . uniqid(5) . time() . '.' . $image->extension();
        $image->move(storage_path('app/public/challenges/'), $imageName);

        $challenge->image_name = $imageName;
        $challenge->category_id = $request->input('category');
        if ($request->input('duration') == 1) {
            $challenge->duration = $request->input('duration_days');
        } else {
            $challenge->duration = 0;
        }
        $challenge->link = $request->input('link');
        $challenge->user_id = Auth::id();
        $challenge->save();

        return redirect('/')->with('success', 'Challenge Created');
    }

这更多的是数据库和迁移的最终问题，然后在laravel上出现错误的格式错误。请尝试：

1）数据库：将数据库默认排序规则更改为utf8mb4。看起来都完成了

2）表：将表排序规则更改为CHARACTER SET utf8mb4 COLLATE utf8mb4_bin。

查询：

更改表表名转换为字符集utf8mb4收集utf8mb4_bin

3）代码：

运行插入查询以获得能够处理表情符号的初始测试插入表名（列名）中的值“”

4）在数据库连接中设置utf8mb4：

使用原始mysql查询编写更新表迁移脚本并运行php artisan migration命令

使用Illuminate \ Database \ Migrations \ Migration;

类UpdateTableCharset扩展了迁移{

/**
 * Run the migrations.
 *
 * @return void
 */
public function up() {
        DB::unprepared('ALTER TABLE `table_name` CONVERT TO CHARACTER SET utf8mb4');
}

/**
 * Reverse the migrations.
 *
 * @return void
 */
public function down() {
        DB::unprepared('ALTER TABLE `table_name` CONVERT TO CHARACTER SET utf8');
}

}

注意：您仍然必须将数据库配置保留为utf8mb4

希望这对您有帮助
