Question

我正在尝试使用here中的示例到目前为止这是我设置的

// angularjs

    // JS
    var presenceClient = new Pusher('API_KEY', {
        authEndpoint: apiServer + "/presence_auth",
        authTransport: 'jsonp',
        encrypted: true            
    })


    var c = pusher.subscribe("presence-testchan")
    Utils.log(c.members.count) // 0
    Utils.log("000============")    
    c.bind('pusher:subscription_succeeded', function(members) {
        Utils.log("succeeded?")
        Utils.log(members)
    })

// golang和存在端点

func Presence(w http.ResponseWriter, r *http.Request, next http.HandlerFunc) {
    params, _ := GetBytes(r.URL.String())

    presenceData := pusher.MemberData{
        UserId: database.GenerateStrObjID(),
        UserInfo: map[string]string{
            "twitter": "pusher",
        },
    }
    response, err := PusherClient.AuthenticatePresenceChannel(params, presenceData)

    if err != nil {
        panic(err)
    }

    respondToJSON(w, string(response))
}


func respondToJSON(w http.ResponseWriter, data interface{}) {

    r := render.New()
    r.JSON(w, http.StatusOK, data)
}

我猜这是基本形式。但我没有得到任何成员的数量？我可以通过

获得API的回复

"{\"auth\":\"7d6e393c49c579c43a0c:6cd45662ef57fbc3ab16d8052c43bf95e7415846f736c2499bac7628ca3b75bc\",\"channel_data\":\"{\\\"user_id\\\":\\\"56f9e5ffcc1cb466a624a3cf\\\",\\\"user_info\\\":{\\\"twitter\\\":\\\"pusher\\\"}}\"}"

但有错误

Uncaught SyntaxError: Unexpected token :

我错过了什么或者我的设置错了吗？

NVM，解决了这个问题..在Go示例的文档中缺少它在jsonp中使用回调函数返回它。响应应该有这样的......

Pusher.auth_callbacks['1']({auth: "7d6e393c49c579c43a0c:33a442fcc9d3bf67febfeeb59e5a8e4f0364901069534cdef006b0b047df9f75",…});
auth:"7d6e393c49c579c43a0c:33a442fcc9d3bf67febfeeb59e5a8e4f0364901069534cdef006b0b047df9f75"
channel_data :"{"user_id":"56fa1231cc1cb48a1cdb243c","user_info":{"twitter":"pusher"}}"

推动者存在无法使用angularjs和golang获得成员
