Laravel JSON验证因邮递员而失败

如何解决Laravel JSON验证因邮递员而失败

我正在使用邮递员向我的Laravel API发送发帖请求。

{
    "title" : "abc","body" : [
        {"type":"paragraph","data":{"text":"aSADAd"}},{"type":"header","data":{"text":"heading......","level":2}},{"type":"paragraph","data":{"text":"This is a para"}},{"type":"list","data":{"style":"ordered","items":["ABC","XYZ"]}}
    ],"status" : 1
}

body字段是JSON数据字段-编辑器js的JSON.stringify输出。

我的laravel验证规则是-

$validator = Validator::make($request->all(),[
            'title' => 'required|string|max:255','body' => 'required|json','status' => 'required|boolean'
        ]);

但是我遇到了这个错误-

{
    "validation_error": {
        "body": [
            "The body must be a valid JSON string."
        ]
    }
}

解决方法

尝试array

$validator = Validator::make($request->all(),[
    'title' => 'required|string|max:255','body' => 'required|array','status' => 'required|boolean'
]);

这将在您设置模型的情况下起作用

/**
 * The attributes that has json type.
 *
 * @var array
 */
protected $casts = [
    'body' => 'array'
];

像这样，您可以在laravel中使用json mysql

注意：数组转换类型在处理以序列化JSON存储的列时特别有用。例如，如果您的数据库具有包含序列化JSON的JSON或TEXT字段类型，则在Eloquent模型中访问该属性时，将数组强制转换为该属性将自动反序列化为PHP数组：
