pusher presence 无法使用 angularjs 和 golang 获取成员

pusher presence can't get members using angularjs and golang

到目前为止,我正在尝试使用 here 中的示例,这就是我的设置

// 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。但我没有得到任何会员数?我可以用

从 API 得到回复
"{\"auth\":\"7d6e393c49c579c43a0c:6cd45662ef57fbc3ab16d8052c43bf95e7415846f736c2499bac7628ca3b75bc\",\"channel_data\":\"{\\"user_id\\":\\"56f9e5ffcc1cb466a624a3cf\\",\\"user_info\\":{\\"twitter\\":\\"pusher\\"}}\"}"

但有错误

Uncaught SyntaxError: Unexpected token :

我是不是遗漏了什么或者我的设置有误?

NVM,解决了问题。在 Go 示例的文档中缺少 return 它在 jsonp 中带有回调函数。响应应该是这样的...

Pusher.auth_callbacks['1']({auth: "7d6e393c49c579c43a0c:33a442fcc9d3bf67febfeeb59e5a8e4f0364901069534cdef006b0b047df9f75",…});
