libreoffice-calc - Macro Webservice Libre Office - 多次调用

Question

我正在从 Libre Office 宏调用网络服务。我使用它将数据从 Calc 传递到网络服务器，但是宏调用了网络服务 5 次，即使该命令只调用了一次：

svc = createUnoService("com.sun.star.sheet.FunctionAccess")
dim ss as string
ss = getWSAdress() + "webservices/" + t
sendWS=svc.callFunction("WEBSERVICE",Array(ss))

我可以避免 Web 服务被调用 5 次吗？

Answer 1

刚测试过。WEBSERVICE在每次调用时发出以下 HTTP 1.1 请求：

PROPFIND /test HTTP/1.1
Keep-Alive: 
Connection: TE, Keep-Alive
TE: trailers
Host: 192.168.0.10:2000

</prop></propfind>

PROPFIND /test HTTP/1.1

HEAD /test HTTP/1.1

GET /test HTTP/1.1

Accept-Encoding: gzip
Pragma: no-cache

所以你是对的。每次调用有 5 个请求。PROPFIND 请求来自 HTTP WebDAV扩展。

因此，要么您的 Web 服务必须支持 WebDAV，要么它必须只对 GET 请求作出反应。
