Couchbase lite - Android 同步问题
Couchbase lite - Android sync issue
我已经创建了一个 Ubuntu 虚拟机 运行 Couchbase 服务器，其中有一个 ships 数据桶，其中加载了许多文档。
我正在尝试在 Android 模拟器中测试将此数据桶简单地拉入 Couchbase lite 数据库 运行。但是我遇到了很多问题！
我创建了一个 config.json 来配置同步网关
{
"log":["CRUD+", "REST+", "Changes+", "Attach+"],
"verbose" : true,
"databases": {
"ships": {
"server":"http://192.168.0.9:8091",
"sync":`function (doc) { channel (doc.channels); }`,
"users": {
"GUEST": {
"disabled": false,
"admin_channels": ["*"]
}
}
}
}
}
当我启动同步网关时，它似乎启动正常
E:\Couchbase>sync_gateway ./data/config.json

在我的 MainActivity class 中，我有以下创建同步的方法 URL
private URL createSyncURL(boolean isEncrypted){
URL syncURL = null;
String host = "https://10.0.2.2";
String port = "4984";
String dbName = "ships";
try {
syncURL = new URL(host + ":" + port + "/" + dbName);
} catch (MalformedURLException me) {
me.printStackTrace();
}
return syncURL;
}
以及调用复制过程的方法
private void startReplications() throws CouchbaseLiteException {
Replication pull = application.getDatabase().createPullReplication(this.createSyncURL(false));
pull.setContinuous(true);
pull.start();
if(!pull.isRunning()) {
Log.d(TAG, "Replication is not running due to " +pull.getLastError().getMessage());
Log.d(TAG, "Replication is not running due to " +pull.getLastError().getCause());
Log.d(TAG, "Replication is not running due to " +pull.getLastError().getStackTrace());
Log.d(TAG, "Replication is not running due to " +pull.getLastError().toString());
}
}
当我调用 startReplications() 方法时，我收到以下异常

我不明白为什么我会收到 404 响应？如果我使用浏览器转到 http://127.0.0.1:4984/ships/_local/ee1ac8f4b732441355817ac7e9446c27e4089efb，我会得到以下 JSON 响应
{"error":"not_found","reason":"missing"}
ships 数据桶肯定存在于 couchbase 服务器上
问题是我通过 Couchbase 服务器上的 cbdocloader 工具将文档添加到 Couchbase。
要使同步正常工作，必须通过同步网关添加它们。我通过同步网关 REST API
进行了批量加载
我已经创建了一个 Ubuntu 虚拟机 运行 Couchbase 服务器，其中有一个 ships 数据桶，其中加载了许多文档。
我正在尝试在 Android 模拟器中测试将此数据桶简单地拉入 Couchbase lite 数据库 运行。但是我遇到了很多问题！
我创建了一个 config.json 来配置同步网关
{
"log":["CRUD+", "REST+", "Changes+", "Attach+"],

"databases": {
"ships": {
"server":"http://192.168.0.9:8091",
"sync":`function (doc) { channel (doc.channels); }`,
"users": {
"GUEST": {
"disabled": false,
"admin_channels": ["*"]
}
}
}
}
}
