graphql/验证

graphql/validation 模块完成了 GraphQL 结果的验证阶段。你可以从 graphql/validation 模块或根 graphql 模块导入。例如：

英：The graphql/validation module fulfills the Validation phase of fulfilling a GraphQL result. You can import either from the graphql/validation module, or from the root graphql module. For example:

import { validate } from "graphql/validation" // ES6
var { validate } = require("graphql/validation") // CommonJS

英：Overview

验证(Validation)#

英：Validation

validate(validate)#

function validate(
  schema: GraphQLSchema,
  ast: Document,
  rules?: Array<any>
): Array<GraphQLError>

实现规范的 "验证" 部分。

英：Implements the "Validation" section of the spec.

验证同步运行，返回遇到的错误的数组，如果未遇到错误且文档有效，则返回空数组。

英：Validation runs synchronously, returning an array of encountered errors, or an empty array if no errors were encountered and the document is valid.

可以提供特定验证规则的列表。如果未提供，将使用 GraphQL 规范定义的默认规则列表。

英：A list of specific validation rules may be provided. If not provided, the default list of rules defined by the GraphQL specification will be used.

每个验证规则都是一个返回访问者的函数（请参阅语言/访问者 API）。访问者方法预计会在无效时返回 GraphQLErrors 或 GraphQLErrors 数组。

英：Each validation rules is a function which returns a visitor (see the language/visitor API). Visitor methods are expected to return GraphQLErrors, or Arrays of GraphQLErrors when invalid.

访问者还可以提供 visitSpreadFragments: true，这将改变访问者的行为以跳过顶层定义的片段，而是在遇到扩展时访问这些片段。

英：Visitors can also supply visitSpreadFragments: true which will alter the behavior of the visitor to skip over top level defined fragments, and instead visit those fragments at every point a spread is encountered.

var specifiedRules: Array<(context: ValidationContext): any>

该集包含 GraphQL 规范定义的所有验证规则

英：This set includes all validation rules defined by the GraphQL spec
