ios - 安装GraphQL iOS框架

Question

我想将apollo框架添加到我的iOS项目中。我正在关注documentation但无法构建它。

我通过cocoapods安装了阿波罗

我向目标添加了代码生成构建步骤(将其置于编译源上方...)

我通过apollo模式下载了该模式:download --endpoint = http://localhost:4000/graphql schema.json。我将schema.json文件添加到项目的根目录中。

我构建了它并得到以下错误:

apollo@1.2.0
在20.385秒内添加416程序包
++ exec /Users/PATH/node_modules/.bin/apollo codegen:generate --queries = --schema = schema.json API.swift
›警告:阿波罗更新从1.2.0到1.7.0
› 错误:标记-查询期望值为
命令/ bin / sh失败，退出代码为2

我的 schema.grapqhl 文件如下所示:

type Query {
  """ User """
  users: [User!]!
  user(username: String!): User

  """ Question """
  questions: [Question!]!
  question(id: Int!): Question

  }

  type Mutation {
  """ User """
    createUser(username: String!): User
    updateUser(username: String!, newUsername: String!): [Int!]!
    deleteUser(username: String!): Int!

  """ Question """
    createQuestion(text: String!, category: Int!, active: Boolean!): 
    Question
    updateQuestion(id: Int!, text: String!, category: Int!, active: Boolean!): [Int!]!
    deleteQuestion(id: Int!): Int!
 }

 type Subscription {
   answerAdded: Answer
 }

 type Question {
  id: Int!
  text: String!
  categoryId: QuestionCategory!
  active: Boolean!
  createdAt: String!
  updatedAt: String!
  }
  ......

似乎查询参数没有输入:
阿波罗代码生成:生成--queries = --schema = schema.json API.swift

如果我自己通过终端尝试

apollo codegen:generate --queries=schema.graphql --schema=schema.json API.swift

我收到以下错误:

Warning: apollo update available from 1.2.0 to 1.7.0

您能帮我找出为什么我无法构建该项目吗？是否因为我的schema.graphl文件错误？

由@Sergej Birklin回答，我想与您分享另一个查询-

Profile.graphql

query MyProfile{
    player {
        me {
            id
            secret
            name
            email
            state
            country
            timezone
            picture
            pictureType
            audio
            rank
        }
    }
}

就像我们只是查询我的个人资料信息(我是 播放器类型)一样，查询将返回我需要的信息，例如我的ID，姓名，电子邮件，状态等。

如您所述，它将创建MyProfileQuery

希望这对您有帮助
