特定规范化和非规范化上下文在 Symfony 5 Api-Platform 中不起作用

如何解决特定规范化和非规范化上下文在 Symfony 5 Api-Platform 中不起作用

我正在关注 Piotr Jura 的 this course。

如您所见，在顶部@ApiResource 注释中，我试图为不同的组设置单独的规范化和非规范化上下文。

当我通过在 localhost:8000/api/users 使用 POST 请求和正文创建用户进行测试时

{
    "username": "test_user1","password": "TestUserPassword1","email": "testUser1@email.com","name": "Test User"
}

我收到此回复

{
    "@context": "/api/contexts/ConstraintViolationList","@type": "ConstraintViolationList","hydra:title": "An error occurred","hydra:description": "username: This value should not be blank.\npassword: This value should not be blank.\nname: This value should not be blank.\nemail: This value should not be blank.","violations": [
        {
            "propertyPath": "username","message": "This value should not be blank.","code": "c1051bb4-d103-4f74-8988-acbcafc7fdc3"
        },{
            "propertyPath": "password",{
            "propertyPath": "name",{
            "propertyPath": "email","code": "c1051bb4-d103-4f74-8988-acbcafc7fdc3"
        }
    ]
}

我在这里做错了什么？请帮忙！！

我正在使用：

PHP 7.4.3
Symfony 5

    }
}

解决方法

您是否确保在向服务器发送 POST 请求时使用 Content-Type: application/json 标头？否则 Symfony 将无法正确解码您的身体负载。
