elasticsearch _bluk 批量导入操作报错。

官方语法：
action_and_meta_data\n
optional_source\n
action_and_meta_data\n
optional_source\n
....
action_and_meta_data\n
optional_source\n
我执行导入操作，加上\n报错：{"took":2,"errors":true,"items":[{"index":{"_index":"test","_type":"testlog","_id":"1","status":400,"error":{"type":"mapper_parsing_exception","reason":"failed to parse","caused_by":{"type":"json_parse_exception","reason":"Unexpected character ('\\' (code 92)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')\n at [Source: org.elasticsearch.common.io.stream.InputStreamStreamInput@25b8faa5; line: 1, column: 47]"}}}},{"index":{"_index":"test","_type":"testlog","_id":"2","status":400,"error":{"type":"mapper_parsing_exception","reason":"failed to parse","caused_by":{"type":"json_parse_exception","reason":"Unexpected character ('\\' (code 92)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')\n at [Source: org.elasticsearch.common.io.stream.InputStreamStreamInput@3b4fbb46; line: 1, column: 47]"}}}}]}
并且数据录不进去。
不加\n数据录进去了，本来4个文档，值录进去3个，也报错：{"took":113,"errors":false,"items":[{"index":{"_index":"test","_type":"testlog","_id":"1","_version":1,"_shards":{"total":2,"successful":1,"failed":0},"status":201}},{"index":{"_index":"test","_type":"testlog","_id":"2","_version":1,"_shards":{"total":2,"successful":1,"failed":0},"status":201}},{"index":{"_index":"test","_type":"testlog","_id":"3","_version":1,"_shards":{"total":2,"successful":1,"failed":0},"status":201}}]}
