用Python请求处理Graphql变异

我正在尝试使用waveapps API。看来我的变异手术做得不对

我想创建一个。下面是我的代码：

query = """ mutation ($input: MoneyTransactionCreateInput!) {moneyTransactionCreate(input: $input) {moneyTransaction {id externalId date description anchor{accountId amount direction} lineItems[{accountId amount balance}]}}}"""

moneyTransaction = {'businessId':'5ODAtNzQ3OS00ZGQ4LTg5NWYtMzU4ZWNiNDNmMTI2', 
'externalId':'21', 'date':'2020-05-16', 'description':'my money', 'anchor':{'accountId':'1', 
'amount':'15.00', 'direction':'DEPOSIT'},
'lineItems':[{'accountId':'1', 'amount':'15.00', 'balance':'CREDIT'}]}

variables = {'input': moneyTransaction}

rex = requests.post(wave_url, json={'query':query, 'variables':variables}, headers=after_headers)

我得到了这个错误：

'{"errors":[{"extensions":{"id":"e6b88a8d-a5f8-4331-80db-191dbb319690","code":"GRAPHQL_PARSE_FAILED"},"message":"Syntax Error: Expected Name, found [","locations":[{"line":1,"column":183}]}]}\n'

我遗漏了一些东西，但无法找出问题所在。我是Graphql新手

您的查询中有多余的方括号。方括号仅在指定列表类型时使用——在选择集中不需要使用它们

mutation ($input: MoneyTransactionCreateInput!) {
  moneyTransactionCreate(input: $input) {
    moneyTransaction {
      id
      externalId
      date
      description
      anchor {
        accountId
        amount
        direction
      }
      lineItems {
        accountId
        amount
        balance
      }
    }
  }
}

这也奏效了

mutation ($inputMoneyTransactionCreate: MoneyTransactionCreateInput!) {
  moneyTransactionCreate(input: $inputMoneyTransactionCreate) {
    didSucceed
    inputErrors {
      code
      message
      path
    }
  }
}

和变量已更改为：

variables = {'inputMoneyTransactionCreate': moneyTransaction}
