node.js – web-push未知问题,WebPushError“收到意外响应代码”400

在使用GCM和chrome开发 web-push期间.我最近遇到过这个问题(几小时前一切都还能正常工作)

我不确定是否由于GCM的某些变化或云的停机而发生这种情况……任何信息都将受到赞赏.

我的代码

var payload = JSON.stringify({
    title: 'notification title',
    body: 'message body'
});
webPush.sendNotification(params.endpoint, {
    userPublicKey: params.userPublicKey,
    userAuth: params.userAuth,
    payload: payload
}).then(function (res) { 
    // console.log of stuff
})
.catch(function(error){
    console.log(error);
    process.exit(1);
});

跟踪：

@Lihn,粘贴你的有效载荷.从错误消息,似乎您发送格式错误的json消息.

您可以使用this service来检查json中的语法问题.

GCM docs声明状态代码400表示无法解析json消息.
