Android Firebase v1 HTTP api不支持嵌套的JSON对象

当前情况

我们发送了一个POST请求

https://fcm.googleapis.com/fcm/send

向我们的Android应用程序提供通知JSON负载。我们的通知负载是标准数据包中的嵌套JSON对象。我们的邮递员有效载荷样本如下所示

{
 "registration_ids": [
   "${registration_id}"],
   "priority":"HIGH", 
 "data": {
   "notification": {
     "title": "Notification Data Title From Postman",
     "body": "Notification Data Body From Postman",
     "imageurl": "https://d2x51gyc4ptf2q.cloudfront.net/content/uploads/2015/10/GettyImages-51205958-700x367.jpg"
   },
   "fcm_options": {
           "analytics_label": "postman"
     }
 }
}

{
  "message": {
    "token": "${token}",
    "data": {
      "notification": {
        "title": "Notification Data Title From v1 API",
        "body": "Notification Data Body From v1 API",
        "imageurl": "https://d2x51gyc4ptf2q.cloudfront.net/content/uploads/2015/10/GettyImages-51205958-700x367.jpg",
        "extra_key": "extra_value"
      }
    },
    "android": {
      "priority": "HIGH",
      "fcm_options": {
        "analytics_label": "Test_Command_line"
      }
    }
  }
}

"data": {
    "title": "Title that is not nested",
    "body": "Body that is not nested",
    "imageurl": "https://timedotcom.files.wordpress.com/2016/08/margot-robbie-beer-shower.jpg",
}

{
  "name": "projects/<project_id>/messages/<message_id>"
}

请求标头如下所示：

Content-Type: application/json; charset=utf-8`
Authorization: key={{server_key}}

在本例中，数据对象中的嵌套JSON对象用于成功构建通知，如下所示

"data": {
       "notification": {
         "title": "Notification Data Title From Postman",
         "body": "Notification Data Body From Postman",
         "imageurl": "https://d2x51gyc4ptf2q.cloudfront.net/content/uploads/2015/10/GettyImages-51205958-700x367.jpg"
       }
}

服务器密钥从Firebase控制台的项目设置中获取。此有效负载已成功交付到适当设备上的Android应用程序，以创建通知

"data": {
       "notification": {
         "title": "Notification Data Title From Postman",
         "body": "Notification Data Body From Postman",
         "imageurl": "https://d2x51gyc4ptf2q.cloudfront.net/content/uploads/2015/10/GettyImages-51205958-700x367.jpg"
       }
}

问题

我们想迁移到。我正在尝试使用验证并向Android设备发送通知。下面给出了我希望通过v1api发送的有效负载

{
 "registration_ids": [
   "${registration_id}"],
   "priority":"HIGH", 
 "data": {
   "notification": {
     "title": "Notification Data Title From Postman",
     "body": "Notification Data Body From Postman",
     "imageurl": "https://d2x51gyc4ptf2q.cloudfront.net/content/uploads/2015/10/GettyImages-51205958-700x367.jpg"
   },
   "fcm_options": {
           "analytics_label": "postman"
     }
 }
}

{
  "message": {
    "token": "${token}",
    "data": {
      "notification": {
        "title": "Notification Data Title From v1 API",
        "body": "Notification Data Body From v1 API",
        "imageurl": "https://d2x51gyc4ptf2q.cloudfront.net/content/uploads/2015/10/GettyImages-51205958-700x367.jpg",
        "extra_key": "extra_value"
      }
    },
    "android": {
      "priority": "HIGH",
      "fcm_options": {
        "analytics_label": "Test_Command_line"
      }
    }
  }
}

"data": {
    "title": "Title that is not nested",
    "body": "Body that is not nested",
    "imageurl": "https://timedotcom.files.wordpress.com/2016/08/margot-robbie-beer-shower.jpg",
}

{
  "name": "projects/<project_id>/messages/<message_id>"
}

当我们向v1httpapi发出httppost请求时，我得到一个400错误，错误消息如下

{
  "error": {
    "code": 400,
    "message": "Invalid JSON payload received. Unknown name \"title\" at 'message.data[3].value': Cannot find field.\nInvalid JSON payload received. Unknown name \"body\" at 'message.data[3].value': Cannot find field.\nInvalid JSON payload received.

    "status": "INVALID_ARGUMENT",
    "details": [
      {
        "@type": "type.googleapis.com/google.rpc.BadRequest",
        "fieldViolations": [
          {
            "field": "message.data[3].value",
            "description": "Invalid JSON payload received. Unknown name \"title\" at 'message.data[3].value': Cannot find field."
          },
          {
            "field": "message.data[3].value",
            "description": "Invalid JSON payload received. Unknown name \"body\" at 'message.data[3].value': Cannot find field."
          },
          {
            "field": "message.data[3].value",
            "description": "Invalid JSON payload received. Unknown name \"imageurl\" at 'message.data[3].value': Cannot find field."
          },
          {
            "field": "message.data[3].value",
            "description": "Invalid JSON payload received. Unknown name \"extra_key\" at 'message.data[3].value': Cannot find field."
          }
        ]
      }
    ]
  }
}

但当数据有效负载未按如下所示嵌套时

{
 "registration_ids": [
   "${registration_id}"],
   "priority":"HIGH", 
 "data": {
   "notification": {
     "title": "Notification Data Title From Postman",
     "body": "Notification Data Body From Postman",
     "imageurl": "https://d2x51gyc4ptf2q.cloudfront.net/content/uploads/2015/10/GettyImages-51205958-700x367.jpg"
   },
   "fcm_options": {
           "analytics_label": "postman"
     }
 }
}

{
  "message": {
    "token": "${token}",
    "data": {
      "notification": {
        "title": "Notification Data Title From v1 API",
        "body": "Notification Data Body From v1 API",
        "imageurl": "https://d2x51gyc4ptf2q.cloudfront.net/content/uploads/2015/10/GettyImages-51205958-700x367.jpg",
        "extra_key": "extra_value"
      }
    },
    "android": {
      "priority": "HIGH",
      "fcm_options": {
        "analytics_label": "Test_Command_line"
      }
    }
  }
}

"data": {
    "title": "Title that is not nested",
    "body": "Body that is not nested",
    "imageurl": "https://timedotcom.files.wordpress.com/2016/08/margot-robbie-beer-shower.jpg",
}

{
  "name": "projects/<project_id>/messages/<message_id>"
}

然后我得到一个200 OK的回复。下面给出了响应主体

{
 "registration_ids": [
   "${registration_id}"],
   "priority":"HIGH", 
 "data": {
   "notification": {
     "title": "Notification Data Title From Postman",
     "body": "Notification Data Body From Postman",
     "imageurl": "https://d2x51gyc4ptf2q.cloudfront.net/content/uploads/2015/10/GettyImages-51205958-700x367.jpg"
   },
   "fcm_options": {
           "analytics_label": "postman"
     }
 }
}

{
  "message": {
    "token": "${token}",
    "data": {
      "notification": {
        "title": "Notification Data Title From v1 API",
        "body": "Notification Data Body From v1 API",
        "imageurl": "https://d2x51gyc4ptf2q.cloudfront.net/content/uploads/2015/10/GettyImages-51205958-700x367.jpg",
        "extra_key": "extra_value"
      }
    },
    "android": {
      "priority": "HIGH",
      "fcm_options": {
        "analytics_label": "Test_Command_line"
      }
    }
  }
}

"data": {
    "title": "Title that is not nested",
    "body": "Body that is not nested",
    "imageurl": "https://timedotcom.files.wordpress.com/2016/08/margot-robbie-beer-shower.jpg",
}

{
  "name": "projects/<project_id>/messages/<message_id>"
}

我随官方的Golang图书馆和它的物品发送如下：

{
 "data": {
   "age":"37",
   "elite":"1",
   "message":"test 4",
   "name":"Денис"},
 "notification":{
   "title":"У Вас 2 новых сообщения!",
   "body":"test 4"},
 "android":{
   "collapse_key":"1",
   "priority":"normal",
   "data":{
     "badge":"2",
     "sound":"1",
     "type":"1"}},
 "fcm_options":{
   "analytics_label":"1"},
 "token":"some_token"}

运气好吗？我也面临同样的问题。@derryltomas将JSON负载字符串化，发送是一个键：值对。在Firebase消息处理程序中反序列化。谢谢！同时我也想到了这一点。我注意到设备上接收到的有效负载似乎与旧API完全相同，这使我得出结论，FCM一直在进行内部串接。你也注意到了同样的情况吗？或者，您是否必须调整应用程序代码中的任何内容以响应从HTTP V1 API接收到的新负载？我不必更改Android代码库，但我的后端服务必须更新模板，并序列化JSON对象。
