發送 IRI 數組時，Symfony ApiPlatform GraphQl 突變失敗

Question

在 Symfony 5 + ApiPlatform v2.6 中使用 GraphQl 突變和 Angular 11 客戶端（Apollo）進行翻譯

1. 需要保存RecipeStepsTranslation 實體來獲取IRI
2. 然后需要保存RecipeStepEntity

執行步驟 1 時一切正常，使用 Promise.all() 獲取 IRI 並將其作為數組傳遞（這是 GraphQl 突變的請求參數）。

這是接收一些必需參數的突變和 IRI 數組（之前創建的翻譯）。 請注意，格式、拼寫錯誤或參數名稱/類型不會引發錯誤或異常。

mutation createRecipeSteps($cookOrder: Int!, $translations: [String]) {
  createRecipeSteps(input: {cookOrder: $cookOrder, translations: $translations}) {
    recipeSteps {
      id
    }
  }
}

// set of variables used
{
  "translations": [
    "/api/recipe_steps_translations/1863",
    "/api/recipe_steps_translations/1864",
    "/api/recipe_steps_translations/1865"
  ],
  "cookOrder": 0
}

發送突變后，我收到以下異常：

正如建議的那樣，我嘗試使用 object 更改語言環境表示（es|en）的鍵，但我得到了相同的異常。

如果我按要求傳遞一個字符串數組，為什么會給我這個錯誤。 提前致謝！

Answer 1

我只是從您處理翻譯和錯誤的事實中猜測，語言環境字符串應該是數組鍵，您示例中的第一個鍵將是int 0 ，它會引發錯誤。

因此，在 php 中，它可能期望類似這樣的字符串關聯數組：

[
  "en" => "/api/recipe_steps_translations/1863",
  "es" => "/api/recipe_steps_translations/1864",
  "fr" => "/api/recipe_steps_translations/1865"
]

在 js 中定義該數據如下所示：

let translations = {
  en: "/api/recipe_steps_translations/1863",
  es: "/api/recipe_steps_translations/1864",
  fr: "/api/recipe_steps_translations/1865"
}

JSON 表示將是：

JSON.stringify(translations)
// or
"{\"en\":\"/api/recipe_steps_translations/1863\",\"es\":\"/api/recipe_steps_translations/1864\",\"fr\":\"/api/recipe_steps_translations/1865\"}"
