Question

我正在Windows（OS）上开发Android移动应用程序。我想将数据发送到couchbase服务器。我在同步网关的URL中犯了错误。我也在我的机器上运行服务。我已经设置了couchbase服务器。

我的config.json文件：

{
"log": ["HTTP+"],
"adminInterface": "127.0.0.1:4985",
"interface": "0.0.0.0:4984",
"databases": {
    "db": {
        "server": "http://localhost:8091",
        "bucket": "mobile_data",
        "users": {
            "GUEST": {"disabled": false, "admin_channels": ["*"] }
        }
    }
}
}

我的Android应用代码：

private void initCouchbase() {


// Create replicators to push & pull changes to & from Sync Gateway.
        URL url = null;
        try {
            url = new URL("http://127.0.0.1:4984/db/");
        } catch (MalformedURLException e) {
        e.printStackTrace();
    }
    Replication push = database.createPushReplication(url);
    Replication pull = database.createPullReplication(url);
    push.setContinuous(true);
    pull.setContinuous(true);

 // Start replicators
    push.start();
    pull.start();
}

我正在使用手机进行测试。

我收到与网址相关的错误。

Answer 1

问题在于您的Android应用网址。你有http://127.0.0.1:4984/db/。这会尝试连接到Android设备本身。

您需要在那里拥有服务器的外部IP地址。您使用"interface": "0.0.0.0:4984"正确配置了同步网关。但要注意，您可以访问（"GUEST": {"disabled": false, "admin_channels": ["*"] }访客，因此您没有安全保障。

如何使用同步网关将数据发送到couchbase服务器，如何连接到同步网关，URL？
