javascript - Joi: "tel"不允许为空

Question

即使 tel 设置为可选，Joi 仍返回以下错误。我们如何解决这个问题？

谢谢。

Error: Joi Failed: ValidationError: child "tel" fails because ["tel" is not allowed to be empty]

---

//Define Joi schema
const schema = {
    email: Joi.string().required().email({
        errorLevel: 64,
        minDomainAtoms: 2 
    }).min(6),
    tel: Joi.string().optional().min(10).max(10),
    password: Joi.string().required().min(8).max(64)
}

//Check inputs
const { error, value } = Joi.validate({ 
    email: args.email, 
    tel: tel, 
    password: args.password 
}, schema)   

Answer 1

...empty strings are not allowed by default and must be enabled with allow(''). However, if you want to specify a default value in case of empty string you have to use a different pattern: Joi.string().empty('').default('default value'). This tells Joi that the empty string should be considered as an empty value (instead of invalid) and which value to use as default.

在你的情况下:

tel: Joi.string().optional().allow('').min(10).max(10)
