solr使用经验总结

.
看了这篇文档解决的，原来是在solr之上，加了个nginx，去掉nginx，直接使用solr的端口访问即可
原文摘录，大致是说使用了user agent，user agent要求请求里包含content-Length，但是估计solrj的请求里木有，所以去掉代理即可

A server MAY reject a request that contains a message body but not a by responding with .

Unless a transfer coding other than chunked has been applied, a client that sends a request containing a message body SHOULD use a valid header field if the message body length is known in advance, rather than the chunked transfer coding, since some existing services respond to chunked with a status code even though they understand the chunked transfer coding. This is typically because such services are implemented via a gateway that requires a content-length in advance of being called and the server is unable or unwilling to buffer the entire request before processing.

A user agent that sends a request containing a message body MUST send a valid header field if it does not know the server will handle HTTP/1.1 (or later) requests; such knowledge can be in the form of specific user configuration or by remembering the version of a prior received response.

400：
addField()里的字段在schemal.xml中没有配置

另一种方法是给nginx添加模块补丁
