Symfony ApiPlatform GraphQl 突变在发送 IRI 数组时失败

如何解决Symfony ApiPlatform GraphQl 突变在发送 IRI 数组时失败

在 Symfony 5 + ApiPlatform v2.6 中使用 GraphQl 突变与 Angular 11 客户端 (Apollo) 进行翻译，我正在展示以下工作流程：

需要保存 RecipestepsTranslation 实体以获取 IRI
然后需要保存 RecipestepEntity

执行第 1 步时一切正常，使用 Promise.all() 获取 IRI 并将其作为数组传递（这是 GraphQl 突变请求的参数）。

这是接收一些必需参数和 IRI 数组（之前创建的翻译）的突变。请注意，没有在格式、拼写错误或参数名称/类型方面引发错误或异常。

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：

正如我所建议的，我试图用一个对象更改语言环境表示（es|en）的键，但我得到了同样的异常。

如果我按要求传递字符串数组，为什么会出现此错误。提前致谢！

解决方法

我只是从你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，你的例子中的第一个键是 int 0 ，它会抛出错误。

所以在 php 中，它可能会期待这样的 associative 字符串数组：

[
  "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
"{\&quot;en\&quot;:\&quot;/api/recipe_steps_translations/1863\&quot;,\&quot;es\&quot;:\&quot;/api/recipe_steps_translations/1864\&quot;,\&quot;fr\&quot;:\&quot;/api/recipe_steps_translations/1865\&quot;}"
