温故GraphiQL学习指南相关笔记，加深对GraphiQL基本类型、查询、突变、订阅的理解
结合项目实际理解对象的传递

mutation CreateReviewForEpisode($episode: Episode!, $review: ReviewInput!) {
  createReview(episode: $episode, review: $review) {
    stars
    commentary
  }
}

apollo.perform(mutation: CreateReviewForEpisodeMutation(episode: .jedi, review: review))

文件上传

mutation UploadFile($file:Upload!) {
    singleUpload(file:$file) {
        id
    }
}

// Create the file to upload
guard
                         fileURL: fileURL) else {
    // Either the file URL couldn't be created or the file couldn't be created.
    return 
}

// Actually upload the file
              files: [file]) { result in 
  switch result {
  case .success(let graphQLResult):
  case .failure(let error):
  }
}

有效上传

mutation AvatarUpload($userID: GraphQLID!, $file: Upload!) {
  id
}

无效上传

// Assumes AvatarObject(userID: GraphQLID, file: Upload) exists
mutation AvatarUpload($avatarObject: AvatarObject!) {
  id
}

note:对象需要使用具体文件，如果上传文件数组需要同名，数量也得对应

    name
    ...HeroDetails
    friends {
