发送 IRI 数组时，Symfony ApiPlatform GraphQl 突变失败

Question

在 Symfony 5 + ApiPlatform v2.6 中使用 GraphQl 突变和 Angular 11 客户端（Apollo）进行翻译

1. 需要保存RecipeStepsTranslation 实体来获取IRI
2. 然后需要保存RecipeStepEntity

执行步骤 1 时一切正常，使用 Promise.all() 获取 IRI 并将其作为数组传递（这是 GraphQl 突变的请求参数）。

这是接收一些必需参数的突变和 IRI 数组（之前创建的翻译）。 请注意，格式、拼写错误或参数名称/类型不会引发错误或异常。

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
}

发送突变后，我收到以下异常：

正如建议的那样，我尝试使用 object 更改语言环境表示（es|en）的键，但我得到了相同的异常。

如果我按要求传递一个字符串数组，为什么会给我这个错误。 提前致谢！

Answer 1

我只是从您处理翻译和错误的事实中猜测，语言环境字符串应该是数组键，您示例中的第一个键将是int 0 ，它会引发错误。

因此，在 php 中，它可能期望类似这样的字符串关联数组：

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

在 js 中定义该数据如下所示：

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

JSON 表示将是：

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