[英]How to validate certain fields of a nested json object using JOI validation
I need help regarding how to validate certain fields of a nested json object using JOI validation. 我需要有关如何使用JOI验证来验证嵌套json对象的某些字段的帮助。 In my example I have an object which contains two sub objects ie
clientObj
and agentObj
. 在我的示例中,我有一个包含两个子对象的对象,即
clientObj
和agentObj
。 I'm only interested in validating the username
field which is required but I don't want to validate the remaining fields. 我只对验证必填的
username
段感兴趣,但我不想验证其余字段。 If I only mention that field, by deleting all other fields, in my schema and joi.validate()
function I get 422 error. 如果我仅提及该字段,则通过删除所有其他字段,在我的架构和
joi.validate()
函数中,我将收到422错误。 Code is given below: 代码如下:
exports.callAuthentication = function (req, res, next) {
let connectSchema = {
clientObj: joi.object().keys({
name: joi.string().min(3).max(38),
email: joi.string().min(3).max(38),
language: joi.string().min(3).max(38),
username: joi.string().min(3).max(38).required(),
mobile_no: joi.string().min(3).max(38),
time_zone: joi.string().min(3).max(38),
system_phone: joi.string().optional().allow('').min(3).max(38),
phone_no_info: joi.any().optional().allow(''),
voicemail_pin: joi.string().min(3).max(38),
display_picture: joi.string().min(3).max(38),
external_extension: joi.string().min(3).max(38)
}),
agentObj: joi.object().keys({
userId: joi.number(),
username: joi.string().min(3).max(38).required(),
name: joi.string().min(3).max(38),
email: joi.string().min(3).max(38),
status: joi.string().min(3).max(38),
role: joi.string().min(3).max(38)
})
};
const data = req.body;
joi.validate(data, connectSchema, (err) => {
if (err) {
// send a 422 error response if validation fails
res.status(422).json({
status: 'error',
message: err.details[0].message
});
} else {
req.body = data;
next();
}
});
}
You can allow unknown keys with { allowUnknown: true }
您可以使用
{ allowUnknown: true }
允许未知密钥
const data = { clientObj: { username: 'username', otherProp: 'otherProp' }, agentObj: { otherProp2: 'otherProp2' } }; const schema = Joi.object().keys({ clientObj: Joi.object().keys({ username: Joi.string().required() }) }); Joi.validate(data, schema, { allowUnknown: true }, (err) => { console.log(`err with allowUnknown: ${err}`); }); Joi.validate(data, schema, { allowUnknown: false }, (err) => { console.log(`err without allowUnknown: ${err}`); });
