Graphql & Validation of GraphQL query document failed

Caused by: org.gradle.process.internal.ExecException: Process 'command '/Users/jake/Documents/code/riseon_android/riseon-parents-android/app/.gradle/nodejs/node-v6.7.0-darwin-x64/bin/node'' finished with non-zero

我们知道，Graphql 不需要后端每个请求都提拱接口，只需要提供一个base接口，就可以访问一系列的数据，按需请求，按需返回数据。

前言

schema.json & *.graphq文件

那么Graph是如何完成这个过程的呢？
依靠schema.json 和 接口定义文件 *.graphql (暂且这么称呼)

作用说明

schema.json 文件
是根据服务器的网络地址通过命令生成的（ios 可以直接生成schema.json，Android 生成可以参考我的另一篇《Graphql & Android 生成 schema.json 文件步骤》），
其主要作用有点类似Android中的binder机制，中介并规范双方通信，加密（个人拙见）

*.graphql文件
可按需建立多个，真正体现graphql灵活性的正在于此！
相当于前端自己在写接口，graph会根据该类文件生成辅助类，而后直接调用就行了

Rise.graphql

附部分文件内容：（需要按照教程语法码）

# 用户登录
mutation Login($mobile:String!, $password: String!) {
  createUserToken(mobile:$mobile,password: $password) {
    id
    token{
        token
      expired_at
      refresh_expired_at
    }
  }
}

在代码中使用

// LoginMutations 是自动生成的
 LoginMutation.builder()
                    .mobile(et_login_phone.text.toString())
                    .password(et_login_password.text.toString())
                    .build().request({
                        loadingDialog.dismiss()
                        startActivity()
                        finish()
                    },{
                        _,_->
                        loadingDialog.dismiss()
                        false
                    })

注意

而我要说的正在于此！下面是我今天在Rise.graphql文件中添加新的配置时的报错：

Caused by: org.gradle.process.internal.ExecException: Process 'command '/Users/jake/Documents/code/riseon_android/riseon-parents-android/app/.gradle/nodejs/node-v6.7.0-darwin-x64/bin/node'' finished with non-zero
error: Validation of GraphQL query document failed

百思不得其解，后来才发现graphql的个别独特的参数类型，导致这个错误，看下面：

id 的类型 是 ID ，而不是 int，我想当然的认为是 int ，导致报错

原来 id 的类型 是 ID ，而不是 int，我想当然的认为是 int ，导致报错

The ID scalar type represents a unique identifier, often used to refetch an object or as key for a cache. The ID type appears in a JSON response as a String; however, it is not intended to be human-readable. When expected as an input type, any string (such as "4") or integer (such as 4) input value will be accepted as an ID.
