我正在尝试HTTP使用基本身份验证将 XML字符串发布到WebMethods服务器.我试图使用位于HTTP Builder之上的REST插件.我尝试过一些事情,导致0长度响应.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.希望有人有一个指针来执行XML的HTTP Post.

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

解决方法

这就是我最终的结果.它是常见HTTP客户端的标准用法

对于SSL上的基本身份验证,您可以使用您的网址：https://user:pass@www.target.com/etc

Grails记得将HTTPClient jar复制到lib文件夹,或者在我的情况下我安装了包含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()
}
