使用Laravel创建API资源

下面是我的数据，我想用这个创建API资源-

array:1 [
  0 => JobPosted {#2635
    -id: 1
    -jobTitle: "Business Development Executive"
    -noOfPosition: 1
    -experience: "2-5"
    -jobLocation: "Mumbai"
    -jobSkill: "Good communication skill, knowledge of Mandarin"
    -jobDescription: "Good communication skill, knowledge of Mandarin"
    -isClosed: false
    -isActive: true
  }
]

我在用拉威尔的教义。 我的工作资源是

public function toArray($request){
        return [
            'jobTitle' => $this->getJobTitle(),
            'noOfPosition' => $this->getNoOfPosition(),
            'experience' => $this->getExperience(),
            'jobLocation' => $this->getJobLocation(),
            'jobSkills' => $this->getJobSkill(),
            'jobDescription' => $this->getJobDescription()
        ];
    }

JobResourceCollection如下所示

 public function toArray($request){
            return parent::toArray($request);
        }

而JobController是

public function getJobs(Request $request){
  $jobs = $this->jobPostedService->getJobPosted($limit);
  return response()->json(new JobResourceCollection($jobs), 200);
}

执行此操作后，我得到的错误如下

Symfony\Component\Debug\Exception\FatalThroTableError （E_ERROR）对数组上的成员函数first（）的调用

---

通过使用解决了该问题

 public function getJobs(Request $request){
  $jobs = $this->jobPostedService->getJobPosted($limit);
  return response()->json(new JobResourceCollection(collect($jobs)), 200);
}

而不是

public function getJobs(Request $request){
  $jobs = $this->jobPostedService->getJobPosted($limit);
  return response()->json(new JobResourceCollection($jobs), 200);
}

请使用jobpostedservice上的getJobPosted方法
