【http】http/1.1 八种请求方式

OPTIONS

返回服务器针对特定资源所支持的HTTP请求方法。也可以利用向Web服务器发送'*'的请求来测试服务器的功能性。

HEAD

向服务器索要与GET请求相一致的响应，只不过响应体将不会被返回。这一方法可以在不必传输整个响应内容的情况下，就可以获取包含在响应消息头中的元信息。

GET

向特定的资源发出请求。注意：GET方法不应当被用于产生“副作用”的操作中。

POST

向指定资源提交数据进行处理请求（例如提交表单或者上传文件）。数据被包含在请求体中。POST请求可能会导致新的资源的建立和/或已有资源的修改。

PUT

向指定资源位置上传其最新内容。

DELETE （后台需要实现逻辑）

请求服务器删除Request-URI所标识的资源。（后台需要有实现逻辑）

TRACE

回显服务器收到的请求，主要用于测试或诊断。

CONNECT
