在复制期间，在沙发底座精简版的安卓模拟器中获取 http 404 错误

Question

在我的Mac 10.9.2中我安装了沙发基础服务器，它正在运行http://127.0.0.1:8091它有它的默认桶，包括啤酒样品

我启动同步服务器为

./sync_gateway -bucket="beer-sample" 

在控制台中记录以下内容

14:00:55.903306 ==== Couchbase Sync Gateway/0.94 ====
14:00:55.979850 Configured Go to use all 2 CPUs; setenv GOMAXPROCS to override this

14:00:56.057680 Starting admin server on 127.0.0.1:4985
14:00:56.090556 Starting server on :4984 ...

在安卓中，我的复制代码看起来像

Replication pullReplication = database.createPullReplication("http://10.0.2.2:4984");
pullReplication.start();

然后我在模拟器中运行我的安卓应用程序，并在更改事件侦听器中记录错误

        if (!replication.isRunning()){
            Log.d(TAG, "Replication is not running due to " + replication.getLastError().getMessage());
            Log.d(TAG, "Replication is not running due to " + replication.getLastError().getCause());
            Log.d(TAG, "Replication is not running due to " + replication.getLastError().getStackTrace());
            Log.d(TAG, "Replication is not running due to " + replication.getLastError().toString());
        }

记录的

Note: I am using 10.0.2.2 instead of 127.0.0.1 because i read in forum that's how simulator maps the host machine. But i also tried 127.0.0.1 earlier which also gives the same result.

同时我在同步网关控制台日志中看到一个新条目，例如

14:05:13.532393 HTTP:  #006: GET /_changes?feed=normal&heartbeat=300000

我试图在浏览器中重复此查询，例如

> http://127.0.0.1:4984/_changes?feed=normal&heartbeat=300000

正在显示

{"error":"not_found","reason":"unknown URL"}

我在这里犯了什么错误？我是沙发基地的新手。

Answer 1

设法克服了这个错误：

在 https://github.com/couchbaselabs/GrocerySync-Android 找到一个参考项目

对我的原始步骤/代码所做的主要更改是

1. 已执行同步网关作为./sync_gateway -bucket="beer-sample" -url=“http://localhost:8091/beer-sample" -verbose

2. 在同步URL中添加了数据库，例如" http://10.0.2.2:4984/beer-sample"，即database.createPullReplication("http://10.0.2.2:4984/beer-sample");

3. 遇到授权错误。通过在终端中执行以下命令来允许匿名访问（暂时）启用GUEST帐户

   curl -X PUT 本地主机：4985/beer-sample/_user/GUEST --data '{"disabled"：false， "admin_channels"：["public"]}'

Answer 2

或者为sync_gateway创建一个配置（例如config.json），如下所示：

{
   "interface":":4984",
   "adminInterface":":4985",
   "log":["REST"],
   "databases":{
      "registratura7":{
         "server":"http://YOUR_IP:8091",
         "bucket":"registratura7",
         "sync":`function(doc) {channel(doc.channels);}`,
         "users": { "GUEST": {"disabled": false, "admin_channels": ["*"] } }
      }
   }
}

然后像这样运行sync_gateway：sync_gateway config.json。这将在 CouchDB 网关上启用 GUEST 帐户。
