我试图执行一个php CURL请求ElasticSearch索引几个条目在同一时间(与_bulk)，但我总是得到基于请求体不同的错误

使用上面的参数字符串，我得到这个错误:
"error":{"root_cause":[{"type":"action_request_validation_exception"，"reason":"Validation Failed: 1: no requests added;"}]，"type":"action_request_validation_exception"，"reason":"Validation Failed: 1:没有添加请求;"},"状态":400}
我用JSON编码的单个请求测试了它，它工作得很好。
那么，如何使用php curl执行_bulk索引呢?

我终于让它工作了!
