如何在scrapy中发起请求时自定义 headers

我一般使用 yield Request()发起请求，尝试过改动settings中的 DEFAULT_REQUEST_HEADERS，也尝试过在Request()的构造函数中传入headers，都没有效果

请问各位强人：如何设置自己设置url的headers 发送到 HTTP server

没记错的话，如下THCAR* szHeader = L"X-Online-Host: 10.0.0.172 ept: /* ";字段名|冒号|空格|字段值|回车换行，依此类推

HttpRequest.headers["token"]=token这边是个什么用法呢

有headers（String s)这个方法吗？是不是getHeaders(java.lang.String name) ？ getHeaderNames public java.util.Enumeration getHeaderNames() Returns an enumeration of all the header names this request contains. If the request has no headers, this method returns an empty enumeration. Some servlet containers do not allow do not allow servlets to ess headers using this method, in which case this method returns null Returns: an enumeration of all the header names sent with this request; if the request has no headers, an empty enumeration; if the servlet container does not allow servlets to use this method, null
