如何将xml数据发布到android中的服务器

Question

因为我是android新手请提供本教程的链接以在服务器上发布xml数据。我面临的问题是执行POST请求

public void uploadFileToServer() 
{ 
     DefaultHttpClient httpClient = new DefaultHttpClient(); 
     HttpPost httppost = new HttpPost(url_context + "/orders/order"); 
     httppost.addHeader("Accept", "text/xml"); 
     httppost.addHeader("Content-Type", "application/xml"); 
     try 
     { 
      StringEntity entity = new StringEntity(xmlString, "UTF-8"); 
      entity.setContentType("application/xml"); 
      httppost.setEntity(entity); 
      HttpResponse response = httpClient.execute(httppost); 
      BasicResponseHandler responseHandler = new BasicResponseHandler(); 
      String strResponse = null; 
      if (response != null) 
      { 
       try { 
        strResponse = responseHandler.handleResponse(response); 
        } catch (HttpResponseException e) 
        { 
         e.printStackTrace(); 
        } catch (IOException e) 
        { 
          e.printStackTrace(); 
        } 
      } 

     } 
     catch (Exception ex) 
     { 
       ex.printStackTrace(); 
     } 
}

了解创建基于这个例子

DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance(); 
    DocumentBuilder docBuilder = docFactory.newDocumentBuilder(); 

    // root elements 
    Document doc = docBuilder.newDocument(); 
    Element rootElement = doc.createElement("Order"); 
    doc.appendChild(rootElement); 

    //set attribute to class 
    Attr Rattr = doc.createAttribute("Order_atrribute"); 
    Rattr.setValue(curtrade); 
    rootElement.setAttributeNode(Rattr); 

     // companyid elements 
     Element staff = doc.createElement("companyid"); 
     rootElement.appendChild(staff); 
     // shorten way 
     // staff.setAttribute("id", "1"); 

     // firstname elements 
     Element firstname = doc.createElement("orderitems"); 
     firstname.appendChild(doc.createTextNode("hii")); 
     staff.appendChild(firstname); 

XML文件和写的内容转换成XML文件

TransformerFactory transformerFactory = TransformerFactory.newInstance(); 
    Transformer transformer = transformerFactory.newTransformer(); 
    DOMSource source = new DOMSource(doc); 
    StreamResult result = new StreamResult(new File(this.getFilesDir().getAbsolutePath(),"file.xml")); 
    //String s=this.getFilesDir().getAbsolutePath(); 
    // Output to console for testing 
    //StreamResult result = new StreamResult(System.out); 
    transformer.transform(source, result); 

通过

DefaultHttpClient httpClient = new DefaultHttpClient(); 
    HttpPost httppost = new HttpPost(url_context + "/orders/order.php"); 
    String filePath = this.getFilesDir().getAbsolutePath(); 
    File f=new File(filePath,"file.xml"); 
    //byte[] data = FileOperator.readBytesFromFile(f); 
    String content=getFileContents(f); 
    StringEntity se = new StringEntity(content, HTTP.UTF_8); 
    se.setContentType("text/xml"); 
    httppost.setEntity(se); 
    f.delete(); 
    HttpResponse httpresponse = httpClient.execute(httppost); 
    Log.d("xml1", httpresponse.toString()); 
    HttpEntity resEntity = httpresponse.getEntity(); 
    Log.d("xml2", resEntity.toString()); 
    String result1 = EntityUtils.toString(resEntity); 
    Log.d("xml", "writer = "+result1); 

梅索德getFileContent上传您的文件

public String getFileContent(final File file) throws IOException { 
    final InputStream inputStream = new FileInputStream(file); 
    final BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream)); 
    final StringBuilder stringBuilder = new StringBuilder(); 

    boolean done = false; 
    while (!done) { 
     final String line = reader.readLine(); 
     done = (line == null); 

     if (line != null) { 
      stringBuilder.append(line); 
     } 
    } 
    reader.close(); 
    inputStream.close(); 

    return stringBuilder.toString(); 
}

按照此tutorial 1，tutorial 2这answer上发送XML数据。

并且对于任何查询都要求您的服务器人员调试您的请求并告诉您确切的问题。
