http - Groovy/Grails 通过 HTTP 发布 XML(使用 REST 插件)

Question

我正在尝试使用基本身份验证将 XML 字符串通过 HTTP 发送到 WebMethods 服务器。我试图使用位于 HTTP Builder 之上的 REST 插件。我已经尝试了一些所有导致 0 长度响应的事情。使用 Firefox 海报我使用了完全相同的 XML 和用户身份验证，WebMethods 响应是用一些额外的信息回显请求，所以我在下面的代码中做的是错误的。希望有人能指导如何进行 XML 的 HTTP 发布。

string orderText = "<item>
  <item>1</item>
  <price>136.000000</price>
</item>"


def response = withHttp(uri: "https://someserver.net:4433") {
      auth.basic 'user', 'pass'

          //  have tried body: XmlUtil.serialize(orderText)
      def r = post(path: '/invoke/document', body: orderText, contentType: XML, requestContentType: XML)
        { resp, xml ->
          log.info resp.status
          log.info resp.data
          resp.headers.each {
            log.info "${it.name} : ${it.value}"
          }
        }
     log.info r
     return r   
}

日志说:

04-02-2011 14:19:39,894 DEBUG HTTPBuilder - Response code: 200; found handler:    OrdersService$_closure1_closure2_closure3_closure4@36293b29

这是我最终得到的。这是常见的 HTTP 客户端的标准用法

对于基于 SSL 的基本身份验证，您可以简单地使用您的网址:https://user:pass@www.target.com/etc

Grails 记得将 HTTPClient jar 复制到 lib 文件夹，或者在我的例子中，我安装了包含 HTTPClient 的 REST 插件。

HTTPClient 站点上有很好的文档:http://hc.apache.org/httpcomponents-client-ga/

import org.apache.http.HttpEntity
import org.apache.http.HttpResponse
import org.apache.http.client.HttpClient 
import org.apache.http.client.methods.HttpPost
import org.apache.http.entity.StringEntity
import org.apache.http.impl.client.DefaultHttpClient

def sendHttps(String httpUrl, String data) {
    HttpClient httpClient = new DefaultHttpClient()
    HttpResponse response
    try {
        HttpPost httpPost = new HttpPost(httpUrl)
        httpPost.setHeader("Content-Type", "text/xml")

        HttpEntity reqEntity = new StringEntity(data, "UTF-8")
        reqEntity.setContentType("text/xml")
        reqEntity.setChunked(true)

        httpPost.setEntity(reqEntity)
        log.info "executing request " + httpPost.getRequestLine()

        response = httpClient.execute(httpPost)
        HttpEntity resEntity = response.getEntity()

        log.info response.getStatusLine()
        if (resEntity != null) {
            log.with {
                info "Response content length: " + resEntity.getContentLength()
                if (isDebugEnabled()) {
                    debug "Response Chunked?: " + resEntity.isChunked()
                    debug "Response Encoding: " + resEntity.contentEncoding
                    debug "Response Content: " + resEntity.content.text
                }
            }
        }
        // EntityUtils.consume(resEntity);
    }
    finally {
        // When HttpClient instance is no longer needed,
        // shut down the connection manager to ensure
        // immediate deallocation of all system resources
        httpClient.getConnectionManager().shutdown()
    }
    return response.getStatusLine()
}
