Java 如何将一堆XML从Android传递到RESTful方法，而不将其放入URL？

我知道如何在C#中实现这一点，事实上我写了一篇关于它的技巧，但我不知道如何在Java/Android中实现它

到目前为止，我的代码是：

protected void doInBackground(String... params) {
    String URLToCall = "http://10.0.2.2:28642/api/DeliveryItems/PostArgsAndXMLFileAsStr";
    String result = "";
    String stringifiedXML = params[0];
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(URLToCall);
    List<NameValuePair> nvp = new ArrayList<NameValuePair>();
    nvp.add(new BasicNameValuePair("serialNum", "42"));
    nvp.add(new BasicNameValuePair("siteNum", "Some Site"));
    try {
        httppost.setEntity(new UrlEncodedFormEntity(nvp));
        HttpResponse response = httpclient.execute(httppost);
        result = response.toString();
    } catch (ClientProtocolException e) {
        Log.e("ClientProtocolException", e.toString());
    } catch (UnsupportedEncodingException uex) {
        Log.e("UnsupportedEncodingException", uex.toString());
    } catch (IOException iox) {
        Log.e("IOException", iox.toString());
    }
}

如您所见，我在URL中传递了两个（小的）VAL（serialNum和siteNum），但是我如何传递stringifiedXML（它相当大，如果塞进URL中，看起来会比满满一堆粉刺状的笨蛋丑陋17倍）

C#客户机代码使用WebClient，但我不知道Java中是否有分析类

更新 作为对阿菲（希望他不是德国人）的回应，根据我所看到的：

那么，你是说，我应该这样设置，而不是我上面所说的：

String result = "";
String stringifiedXML = params[0];
String serNum = params[1];
String siteNum = params[2];

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(URLToCall);
List<NameValuePair> nvp = new ArrayList<NameValuePair>();
nvp.add(new BasicNameValuePair("stringifiedXML", stringifiedXML));

…使用所有这些调用服务器：

String URLToCall = builder.build().toString();
try {
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(URLToCall);
    httppost.setEntity(new UrlEncodedFormEntity(nvp));
    HttpResponse response = httpclient.execute(httppost);
    result = response.toString();

…调用AsyncTask的代码如下：

_postDeliveryItemTask = new PostDeliveryItemTask();
_postDeliveryItemTask.execute(XMLFileAsStr, "42", "some Site");

?

更新2 显然不是，因为代码在到达“

HttpResponse response=httpclient.execute（httppost）；

”时记录了以下内容：

为什么在主机名为“10.0.2.2:28642”时，它会声称“由以下原因引起：java.lang.IllegalArgumentException:主机名可能不为null”，对吗

URLToCall最终成为“

http://10.0.2.2%3A28642%2Fapi/DeliveryItems/PostArgsAndXMLFileAsStr?serialNum=42&siteNum=some%20Site

“

使用StringEntity而不是FormEntity？您是说StringEntity代表XML，FormEntity代表其他两个参数吗？可能吗？我知道（非常确定）您不能将多个带有[FromBody]装饰/注释的arg传递给Web API…您希望在请求正文中同时包含表单编码数据和xml吗？或者您希望这两个参数位于查询字符串中？您可以使用URI生成器生成URI，以将它们放入查询字符串中，而不是将它们放入请求实体中。+1仅用于Hitchhiker引用，如果您希望将数据作为名为“stringifiedXML”的表单参数输入。要使主体仅为实际的XML，如果要将其自动编组到服务器中的对象中，通常需要使用StringEntity

_postDeliveryItemTask = new PostDeliveryItemTask();
_postDeliveryItemTask.execute(XMLFileAsStr, "42", "some Site");
