Node抛出错误时NodeJS抛出UnhandledPromiseRejectionWarning

Posted 2023-02-20

当用户有意输入错误的objectId时，我想处理该错误，但是当我在函数检查objectID中压缩该错误时，出现此错误：UnhandledPromiseRejectionWarning：错误：INVALID_ID

功能检查对象ID：

function checkObjectId(...ids) 
    ids.forEach(id => 
        const objectId = mongoose.Types.ObjectId.isValid(id);
        if (!objectId) throw new MyError('INVALID_ID',404);
    );

服务：

static async updateAuthor(_id, content) 
    checkObjectId(_id);
    const author = await Author.findByIdAndUpdate(_id, content,  new: true );
    if (!author) throw new MyError('CAN_NOT_FIND_AUTHOR', 404);
    return author;

路由器：

    routerAuthor.put('/:_id',async (req, res) => 
        AuthorService.updateAuthor(req.params._id,req.body)
        .then(author => res.send(success : true, author))
        .catch(res.onError);
    );
app.use((req, res, next) => 
    res.onError = function(error) 
        const body =  success: false, message: error.message ;
        if (!error.statusCode) console.log(error);
        res.status(error.statusCode || 500).send(body);
    ;
    next();
);

答案

static async updateAuthor(_id, content) try checkObjectId(_id); const author = await Author.findByIdAndUpdate(_id, content, new: true ); if (!author) throw new MyError('CAN_NOT_FIND_AUTHOR', 404); return author; catch (e) throw new Error(e);
