如何在Vapor中向Firebase云消息API发送POST请求

我试图使用Vapor 1.5和Firebase遗留协议向Firebase Notifications API发出POST请求，但收到失败响应

响应是JSON（节点：node.node.object（[“multicast\u id”： 节点号（5936281277445399934），“故障”：节点号（0）， “规范的_id”：Node.Node.number（0），“results”： Node.Node.array（[Node.Node.object（[“message_id”）： Node.Node.string（“0:1527074314969790%c7ade8b9f9fd7ecd”））]， “成功”：节点.节点.编号（1）]）

编辑 通过邮递员发出请求失败，错误为“请求缺少身份验证密钥（FCM令牌）”

在

发送通知（有效负载：）

中，我有一个输入错误，我错过了键后的

=

。它应该是

“key=\（fcmLegacyServerKey）”

在

sendNotification（payload:）

中，不应调用

payload.makeBody

，我应该将JSON对象

payload

作为参数传递给.post请求

通知的JSON对象显然从一开始就格式不好。我想发送的消息类型是通知，但我传入了一个名为

aps

的密钥。我应该已通过键

通知

，如下所示

嘿，比尔西。看到你在上一篇文章中的评论，来到这里。我以前没有使用过vapor，但是授权值的格式是否应该像

“key\（fcmLegacyServerKey）”

？它不应该是普通服务器键值吗？如果这不起作用，也许可以遵循通过邮递员发送的格式，即“key=（fcmLegacyServerKey）”？@AL。我附上了邮递员的屏幕截图，该请求也返回401。那应该是200美元。现在，回到您的问题fcmLegacyServerKey:String是一个变量，所以使用“key=（fcmLegacyServerKey）”是合法的，本质上就像“key=123456AA”
