PHP：我可以在它的第一个深度上拆分 JSONstring 而不必重新编码吗？

Question

因为我不知道 behat 是否可以用字符串以外的任何东西注入我的 Behat FeatureContext 函数参数，所以我想知道我是否可以拆分字符串，这样我就可以得到 json_objects.

我已经设法用 json_decode 和 json_encode 做到了这一点，但是当我第一次解码对象字符串时感觉有点重复，仅将其编码回单个对象。

每个示例具有以下 Behat 功能：

Feature: Provide a consistent standard JSON API endpoint

  In order to build interchangeable front ends
  As a JSON API developer
  I need to allow Create, Read, Update, and Delete functionality

  Background:
    Given there are Albums with the following details:
      """
      [{
        "artist":"Pink Floyd",
        "title":"The Dark Side of the Moon",
        "songs":[
          {"title":"Speak to Me", "length":254}
          {"title":"Breathe", "length":192}
          {"title":"On the Run", "length":188}
        ] 
      },
      {
        "artist":"AC/DC",
        "title":"Back to Black",
        "songs":[
          {"title":"Hells Bells", "length":205}
          {"title":"Shoot to Thrill", "length":302}
          {"title":"What Do You Do for Money Honey", "length":244}
        ] 
      }]    
      """
      And the "Content-Type" request header is "application/json"

和 FeatureContext.php 中的以下函数：

...

public function thereAreAlbumsWithTheFollowingDetails(string $jsonString) {
    $albums = json_decode($jsonString, true);

    foreach ($albums as $album) {
        $albumJson = json_encode($album);
        $this->apiContext->setRequestBody($albumJson);
        $this->apiContext->requestPath("/api/album", "POST");
    }
}

...

Answer 1

据我了解，您想添加一些数据来设置场景，在这种情况下，我会放弃 json，因为那是一个实现细节：

Given there are Albums with the following details:
  | artist     | title                     | songs                            |
  | Pink Floyd | The Dark Side of the Moon | Speak to Me, Breathe, On the Run |
  | AC/DC      | Back to Black             | Hells Bells, Shoot to Thrill, What Do You Do for Money Honey |
...

然后在 FeatureContext 上将数据转换为 json 如果你需要的话，但就个人而言，如果你做对了，我会注入相同的服务应该在 /api/album 控制器中使用它来创建相册。

我正在学习通过 REST 添加第一个测试对象的教程，但这并不一定会发生。

我还了解到 Behat 的嵌套表格不是一个好主意。

https://joebuschmann.com/specflow-nested-tables-a-bad-idea/

behat.yml

default:
    suites:
        default:
            contexts:
                - App\Features\Bootstrap\FeatureContext:
                    container: '@service_container'
                    entityManager: "@doctrine.orm.default_entity_manager"
                - Imbo\BehatApiExtension\Context\ApiContext
    extensions:
        Imbo\BehatApiExtension:
            apiClient:
                base_uri: http://127.0.0.1:8000
        Behat\Symfony2Extension:
            kernel:
                bootstrap: config\behat\bootstrap.php
                class: App\Kernel

下面的代码不完全正确，但已经足够接近了。

FeatureContext.php

...

/**
     * @Given there are Albums with the following details:
     */
    public function thereAreAlbumsWithTheFollowingDetails(TableNode $table) {
        foreach ($table->getColumnsHash() as $row) {
            $album = new Album();
            $album->setTitle($row['title']);
            $album->setReleaseDate(new \DateTime($row['release_date']));
            array_push($this->entities, $album);
        }
        $this->em->flush();
    }

    /**
     * @Given albums with the following Songs:
     */
    public function albumsWithTheFollowingSongs(TableNode $table) {
        $i = 0;
        foreach ($table->getColumnsHash() as $row) {
            $song = new Song($row['title']);
            $this->entities[$i]->setSong($song);
            $i = $i + 1;
        }
    }

    /**
     * @When they are saved into the database
     */
    public function theyAreSavedIntoTheDatabase() {
        foreach ($this->entities as $entity) {
            $this->em->persist($entity);
        }
        $this->em->flush();
    }
...
