JSON Schema的验证机制很简单,首先你需要维护一份JSON文件,这个文件就是标准的你想要的JSON文件格式,例如: {"definitions": {},"$schema": "http://json-schema.org/draft-07/schema#","$id": "http://example.com/root.json","type": "object","title": "The Root Schema","required": ["checked"...

添加对teacherName属性的约束后,JSON Schema如下,其中: 往properties中加入了teacherName的描述和约束信息 往required列表中加入teacherName字段 { "$schema": "http://json-schema.org/draft-07/schema#", "$id": "http://example.com/teacher.schema.json", "title": "老师信息", "description": "柠檬班的...
For example, to create a collection that holds longitude and latitude values and require validating those values as numbers: MySQL Shell JavaScript Code var coll = schema.createCollection("longlang", { validation: { level: "strict", schema: { "id": "http://json-schema.org/geo", "$...
在这个例子中，我们介绍一个新的 JSON Schema，里面包含两个属性:使用 minmimum 校验关键字使用 maximum 校验关键字组合这两个，产生一个 range (范围的校验){ // 前面提到了，id 可以作为引用的 URI "$id": "https://example.com/geographical-location.schema.json", "$schema": "http://json-schema...
For example, this schema validation does not allow documents wherestoreLocationisnull: db.createCollection("sales", { validator: { "$jsonSchema": { "properties": { "storeLocation": {"bsonType":"string"} } } } } ) With the preceding validation, this document is rejected: ...
创建JSON Schema 在src/main/resources目录下创建一个validation.json文件,然后在里面制定一套详尽的验证规则,比如下面这样: 复制 { "$schema": "http://json-schema.org/draft-07/schema#", "title": "Order Event", "description": "Order event schema for example", ...
The following example inserts documents that comply with the above schema validation rules: db.employees.insert({"name" : { "firstName" : "Carol" , "lastName" : "Smith"}, "employeeId": "c720a" , "salary": 1000.0 }) db.employees.insert({ "name" : { "firstName" : "William", "...
You can combine JSON Schema validation with query operator validation. For example, consider a sales collection with this schema validation: db.createCollection("sales", { validator: { "$and": [ // Validation with query operators { "$expr": { "$lt": ["$lineItems.discountedPrice", "$line...
描述性关键字在Json Schema中并不会产生实际的约束,但是对于阅读和理解Json Schema中相关约束有非常大的帮助。可以理解为Json Schema对于Json数据的说明文档。 描述性关键字主要包括: title:描述对象的标题 Description:对数据进行说明描述 default:所描述对象的默认值 example:从draft 06支持的关键字,提供当前约束的示例...
