Question

我正在尝试使用批量api发布以下内容。我有ES 2.2.0

{"index":{"_index":"junktest","_type":"test"}}
{"DocumentID":"555662","Tags":["B","C","D"],"Summary":"Summary Text","Status":"Review","Location":"HDFS","Error":"None","Author":"Abc Mnb","Sector":"Energy","Created Date":"2013-05-23"},
{"DocumentID":"555663","Tags":["A","B","C"],"Summary":"Summary Text","Status":"Review","Location":"HDFS","Error":"None","Author":"Abc Mnb","Sector":"Energy","Created Date":"2013-04-25"}

作为

curl -XPOST "http://localhost:9200/_bulk" --data-binary @post.json

但是我得到了

  {"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Malformed
     action/metadata line [3], expected START_OBJECT or END_OBJECT but found [VALUE_
STRING]"}],"type":"illegal_argument_exception","reason":"Malformed action/metadata line [3], expected START_OBJECT or END_OBJECT but found [VALUE_STRING]"},"status":400}

为什么},无效？我甚至没有使用逗号尝试过，但我仍然得到错误，即使我没有,！

我的语法有什么问题？

修改

我能够通过

让它工作

{"index":{"_index":"junktest","_type":"test"}}
{"DocumentID":"555662","Tags":["B","C","D"],"Summary":"Summary Text","Status":"Review","Location":"HDFS","Error":"None","Author":"Abc Mnb","Sector":"Energy","Created Date":"2013-05-23"}
{"index":{"_index":"junktest","_type":"test"}}
{"DocumentID":"555663","Tags":["A","B","C"],"Summary":"Summary Text","Status":"Review","Location":"HDFS","Error":"None","Author":"Abc Mnb","Sector":"Energy","Created Date":"2013-04-25"}

这是使用批量api索引多个记录的唯一方法吗？

Answer 1

来自文档

REST API端点是/ _bulk，它需要以下JSON 结构：
INTERNET

action_and_meta_data\n optional_source\n action_and_meta_data\n optional_source\n .... action_and_meta_data\n optional_source\n是可选的，但document source是强制性的，两者用新行分隔。鉴于这些限制，您只能为每个操作指定一条记录。

同样在您提供的示例中，您没有在元数据中传递“_id”，这意味着“_id”是自动生成的。可能是故意的，但请记住，如果您打算更新文档，则无法使用action_meta_data。

最后一条记录之后的换行符对于让它正常工作非常重要。我通过在最后一条记录的末尾添加\ n（换行符）解决了类似的问题。

e.g。这不起作用：

＆＃34; {＆＃34; name＆＃34;：＆＃34; Central School＆＃34;，＆＃34; description＆＃34;：＆＃34; CBSE Affiliation＆＃34;，＆＃34;街道＆＃34;：＆＃34;哪敢＆＃34;}＆＃34;

但这将

＆＃34; {＆＃34; name＆＃34;：＆＃34; Central School＆＃34;，＆＃34; description＆＃34;：＆＃34; CBSE Affiliation＆＃34;，＆＃34;街＆＃34;：＆＃34; Nagan＆＃34;} \ n ＆＃34;

Answer 3

JSON结构中应该没有换行符，之前我正在使用此输入，它产生了上述错误，

{ 
"index" : { "_index" : "ecommerce", "_type" : "product", "_id" : "1002" 
} 
}
{ "id": 2}

现在它可以正常使用以下输入

{ "index" : { "_index" : "ecommerce", "_type" : "product", "_id" : "1002" } }
{ "id": 2}
{"index":{ "_index" : "ecommerce", "_type" : "product","_id":"1003"}}
{ "id": 3,"name":"Dot net"}
