【问题描述】：

我正在尝试弄清楚如何使用 GraphQL 向 strpi 后端（使用 React/Apollo）查询“小于”/“大于”。基本上我希望奖金数额“不小于”$min_bonus，并且“不大于”然后 $max_bonus...

什么是解决这个问题的好方法？

我的查询：

import { gql } from "@apollo/client";


const BONUSES_QUERY = gql`

query bonuses($min_bonus, $max_bonus, $welcome_bonus: Boolean, $deposit_bonus: Boolean, $monthly_bonus: Boolean, $weekly_bonus: Boolean, $slots_bonus: Boolean, $nodeposit_bonus: Boolean ) {
    
  welcome_bonuses: bonuses(where: 
    { 
      welcome_bonus: $welcome_bonus
      
    })
  {
    ...BonusParts
  }

  deposit_bonuses: bonuses(where: { deposit_bonus: $deposit_bonus })
  {
    ...BonusParts
  }

  monthly_bonuses: bonuses(where: { monthly_bonus: $monthly_bonus })
  {
    ...BonusParts
  }

  weekly_bonuses: bonuses(where: { weekly_bonus: $weekly_bonus })
  {
    ...BonusParts
  }

  slots_bonuses: bonuses(where: { slots_bonus: $slots_bonus })
  {
    ...BonusParts
  }

  nodeposit_bonuses: bonuses(where: { nodeposit_bonus: $nodeposit_bonus })
  {
    ...BonusParts
  }

}
fragment BonusParts on Bonuses {
          name
          casino { 
            name
            aff_link
            logo { 
              url 
            }
          }
          slug
          title
          amount
          code
          min_deposit
          value
          wager
          cashable
          bonus_type {
            name
          }      
  }


`;

export default BONUSES_QUERY;

【解决方案1】：

您说您想要大于和小于，但您的描述表明您想要大于或等于且小于或等于，所以我的建议是。如果您不想包含限制，您可以将_gt 转为_gte 等。

Here is the relevent Strapi documentation.

您可以像这样将_gte 和_lte 附加到where 子句中的字段。

import { gql } from "@apollo/client";


const BONUSES_QUERY = gql`

query bonuses($min_bonus, $max_bonus, $welcome_bonus: Boolean, $deposit_bonus: Boolean, $monthly_bonus: Boolean, $weekly_bonus: Boolean, $slots_bonus: Boolean, $nodeposit_bonus: Boolean ) {
    
  welcome_bonuses: bonuses(where: 
    { 
      deposit_bonus_gt: $min_bonus, 
      deposit_bonus_lt: $max_bonus,
      welcome_bonus: $welcome_bonus
      
    })
  {
    ...BonusParts
  }

  deposit_bonuses: bonuses(where: 
    { 
      deposit_bonus_gt: $min_bonus, 
      deposit_bonus_lt: $max_bonus,  
      deposit_bonus: $deposit_bonus 
    })
  {
    ...BonusParts
  }

  ...
