我知道如何在C＃中做到这一点，其实我写了一个提示它在这里 ，但我不知道如何完成它的Java / Android系统。
我的代码是这样的，到目前为止：
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());
}
}
在Web API方法开始是这样的：
[Route("api/DeliveryItems/PostArgsAndXMLFileAsStr")]
public void PostArgsAndXMLFileAsStr([FromBody] string stringifiedXML, string serialNum, string siteNum)
{
XDocument doc = XDocument.Parse(stringifiedXML);
正如你所看到的，我传递了两个（小）瓦尔斯在URL（SERIALNUM和siteNum），但我怎么能传递stringifiedXML（这是相当大的，而且看起来比17X麻点劳斯的lockerroomful丑陋如果塞到URL）？
C＃的客户端代码使用WebClient的，但我不知道是否有在Java中，以相似的类。
UPDATE
为了响应是Affe（希望他不是德国），并根据我所看到的在这里 ：
所以你说什么，而不是我上面，我应该对其进行设置，如下所示：
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));
......那么这样使用UriBuilder：
Uri.Builder builder = new Uri.Builder();
builder.scheme("http").authority("10.0.2.2:28642").appendPath("api").appendPath("DeliveryItems").appendPath("PostArgsAndXMLFileAsStr").appendQueryParameter("serialNum", "42").appendQueryParameter("siteNum", "Some Site");
...使用所有调用服务器：
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();
...用代码来调用的AsyncTask是像这样：
_postDeliveryItemTask = new PostDeliveryItemTask();
_postDeliveryItemTask.execute(XMLFileAsStr, "42", "some Site");
？
更新2
显然不是，作为代码结束了，在到达“ HttpResponse response = httpclient.execute(httppost); ” Logcatting这样的：

为什么声称，“ 产生的原因：java.lang.IllegalArgumentException异常：主机名不能为空 ” 时提供的主机名-为“10.0.2.2:28642” -对吗？
URLToCall最终被“ http://10.0.2.2%3A28642%2Fapi/DeliveryItems/PostArgsAndXMLFileAsStr?serialNum=42&siteNum=some%20Site ”
