r - 如何将 SOAP 请求 curl 转换为 RCurl

Question

我应该如何转换这个类轮:

curl -d @request.xml -o response.xml http://www.sample.com/soap

它正在访问如下所示的请求 xml:

<?xml version="1.0" encoding="utf-8"?>
     <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:req="http://sample.com/">
    <soap:Body>
      <req:getEvents>
        <start>2014-12-12T00:00:00+0100</start>
        <end>2014-12-13T00:00:00+0100</end>
        <type>TYPE</type>
      </req:getEvents>
     </soap:Body>
    </soap:Envelope>

响应写入 response.xml
我想将响应直接读入 r

Answer 1

以下是 httr 的方法:

library(httr)
r <- POST("http://www.sample.com/soap", body = upload_file("request.xml"))
stop_for_status(r)
content(r)
