使用cURL想接口发送数据,出现等待相应的时间很长的现象,怎么解决。
背景:java提供一个地址,我用自己本地的浏览器(环境用的WAMP Server)访问这个地址,很快,非常快,就能得到数据。
现在转到生产环境上,我用cURL访问这个地址,发送数据,完,出现很大的问题。
具体问题:在页面上点一下用cURL向那个地址发送,我获得返回的数据,我以为会像我本地测试的一样快,非也,有的快,有的慢,有的慢的要死,我用Firebug一看,出现的问题都是在等待相应的时间很长上,如下图。
思考: 我觉得问题不该处在java上,毕竟用浏览器访问获得数据是非常快的,那么问题只能出现在PHP上,是用了cURL出的问题?还是说服务器配置有什么问题?请大家多多提出意见。

你可以拿多几台服务器测试一下,用排除法。
我自己采集完数据后再返回速度都是正常的。
类似远程调用可以参考SOAP
可能和网络状况有关系吧。1、检查一下服务器到java服务那台机器的网络,简单测试使用 ping ;2、看看服务器的DNS 配置。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
