Question

您想帮我吗？我有这样的一个ajax

var id = {{@$projectid}};
var datatab = JSON.stringify({data: change})
$.ajax({
  url: 'save/'+id,
  type: 'POST',
  dataType: 'JSON',
  data: {json:datatab},
  success: function(response, textStatus, jqXHR) {
});

然后，我想将datatab作为json传递到json字段中的数据库这是我在控制器中的保存功能

 public function save($project_id=0, Request $request)
 {
    $project_id = $request->project_id;
    $weight = $request->weight;

    TaskPlanning::create([
        'project_id' => $project_id,
        'weight' => $weight
    ]);

    return response()->json([]);
}

在数据库中，权重字段为json。我想将我的json文件从ajax保存为weight 这是我的模特

class TaskPlanning extends Model
{
    protected $table = 'p_task_planning';
    protected $fillable = ['project_id','weight'];

    public function project()
    {
        return $this->belongsTo(Project::class,'project_id','id');
    }

    public function milestone()
   {
       return $this->belongsTo(Milestone::class,'milestone_id','id');
   }

   protected $casts = [
      'weight' => 'array'
   ];
 }

Answer 1

尝试一下

var id = {{@$projectid}};
var datatab = JSON.stringify({data: 'change'});
$.ajax({
  url: 'save/'+id,
  type: 'POST',
  dataType: 'JSON',
   data: {_token   : '{!! csrf_token() !!}',
          weight   : datatab,
          project_id : id 
         },
  success: function(response, textStatus, jqXHR) {
});

Answer 2

使用 axios 代替$ .ajax。

请确保您添加了元标记

<meta name="csrf-token" content="{{ csrf_token() }}" >

然后

像这样使用axios ..它将自动加载csrf令牌

axios.post('save/'+id, data).then(function (response) {
    //response
});

将json从ajax传递到laravel控制器
