Question

我的数据库有很多文档，每个文档都有一个名为doc_type的字段，所以我可以过滤它，但android在尝试过滤时出错：

Map<String, String> parameters = new HashMap<String, String>();
        parameters.put("doc_type", "doc_company");
        PullFilter filter = new PullFilter("company/list", parameters);
        Replicator replicator = ReplicatorBuilder.pull()
                .from(uri).to(ds)
                .filter(filter)
                .build();

错误：

       CouchException: error: Unknown error, reason: Unknown reason, statusCode: 404, msg: Object Not Found, cause: java.io.FileNotFoundException: https://(my_user_here).cloudant.com:443/db_404040/_changes?style=all_docs&feed=normal&filter=company/filter&doc_type=doc_company&limit=1000

我有带过滤功能的文件：

{
  "_id": "_design/company",
  "_rev": "15-49d2081b2e3c35ae833617fd2356e6d3",
  "views": {
    "list": {
      "map": "function (doc) {\n  emit(doc);\n}"
    },
    "filter": {
      "map": "function (doc, req) {\n  emit(doc._id, 1);\n}"
    }
  },
  "language": "javascript"
}

当我访问

时

https://(my_user_here).cloudant.com:443/db_404040/_changes?style=all_docs&feed=normal&filter=company/filter&doc_type=doc_company&limit=1000

它给了我这条消息：

{"error":"not_found","reason":"missing json key: filters"}

怎么了？我完全按照文件说https://github.com/cloudant/sync-android/blob/master/doc/replication.md（最后）

我找到了 - ＆gt; groups.google.com/forum/#!topic/mobile-couchbase/tw5462qMFeM

我从cloudant数据库（在线）中删除了_replicator文档并开始工作

Cloudant同步android过滤拉
