Question

我是GraphQL的新手，从事AWS AppSync并使用POSTMAN进行测试

我创建了API，并且能够运行createMutation和List查询

这是我的模式

input CreateUserInput {
    id: ID!
    name: String!
    gender: String!
    email: String!
    password: String!
}

input DeleteUserInput {
    id: ID!
    name: String!
}

type Mutation {
    createUser(input: CreateUserInput!): User
    updateUser(input: UpdateUserInput!): User
    deleteUser(input: DeleteUserInput!): User
}

input UpdateUserInput {
    id: ID!
    name: String!
    gender: String
    email: String
    password: String
}

type User {
    id: ID!
    name: String!
    gender: String!
    email: String!
    password: String!
}

以下在POSTMAN中的工作原理：

查询：

mutation createUser($createuserinput: CreateUserInput!) {
  createUser(input: $createuserinput) {
    id
    name
    gender
    email
    password
  }
}

变量

{
  "createuserinput": {
    "id": "AAAUzF6XsJUCJ7tJw0NREODencTOp6wES",
    "name": "Somename",
    "gender": "male",
    "email": "some@email",
    "password": "12345"
  }
}

以下操作无效

查询

mutation updateUser($updateuserinput: UpdateUserInput!) {
  updateUser(input: $updateuserinput) {
    id
    name
    gender
    email
    password
  }
}

变量

{
  "updateuserinput": {
    "id": "AAAUzF6XsJUCJ7tJw0NREODencTOp6wES",
    "name": "Somename2",
    "gender": "male",
    "email": "some@email2",
    "password": "123456"
  }
}

我得到了错误：

{
    "data": {
        "updateUser": null
    },
    "errors": [
        {
            "path": [
                "updateUser"
            ],
            "data": null,
            "errorType": "DynamoDB:ConditionalCheckFailedException",
            "errorInfo": null,
            "locations": [
                {
                    "line": 2,
                    "column": 3,
                    "sourceName": null
                }
            ],
            "message": "The conditional request failed (Service: AmazonDynamoDBv2; Status Code: 400; Error Code: ConditionalCheckFailedException; Request ID: MG0N1EP32Q7D946OU4JODOQHH7VV4KQNSO5AEMVJF66Q9ASUAAJG)"
        }
    ]
}

我认为该ID未正确传递。我在这里做什么错了？

Answer 1

我找到了问题。

在变异更新和删除中，名称被标记为必填。我还必须传递名称才能更新/删除。

示例：

data = [[
        1 2 3
        4 5 6
        7 8 9

    2 3 4
    5 7 8
    9 1 2

    ]]
--------------------------------------------------------------------------------
local cc = table.concat
--------------------------------------------------------------------------------
function save_csv(filenumber,t)
  io.open(filenumber .. '.csv','w'):write(cc(t,'\n')):close()
end
--------------------------------------------------------------------------------
local filenumber = 1
local ans = {}
for line in (data..'\n'):gmatch '(.-)\n' do
  local s = {}
  for item in line:gmatch '%d+' do s[#s+1] = item end
  if #s > 0 then
    ans[#ans+1] = cc(s,',')
  elseif #ans > 0 then
    save_csv(filenumber,ans)
    filenumber = filenumber + 1
    ans = {}
  end
end

在创建模型时选择名称作为排序键时发生了这种情况

GraphQL更新和删除突变不起作用
