如何发布XML数据在安卓服务器 [英] how to post xml data to server in android
本文介绍了如何发布XML数据在安卓服务器的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
由于我是新到Android请为我提供的教程的链接来发布XML数据的服务器上。我面临的问题是执行职务的请求
公共无效uploadFileToServer（）
{
DefaultHttpClient的HttpClient =新DefaultHttpClient（）;
HttpPost httppost =新HttpPost（url_context +/命令/命令）;
httppost.addHeader（接受，为text / xml）;
httppost.addHeader（内容类型，应用程序/ XML）;
尝试
{
StringEntity实体=新StringEntity（的xmlString，UTF-8）;
entity.setContentType（应用程序/ XML）;
httppost.setEntity（实体）;
HTT presponse响应= httpClient.execute（httppost）;
BasicResponseHandler ResponseHandler的=新BasicResponseHandler（）;
字符串strResponse = NULL;
如果（响应！= NULL）
{
尝试 {
strResponse = responseHandler.handleResponse（响应）;
}赶上（Htt的presponseException E）
{
e.printStackTrace（）;
}赶上（IOException异常E）
{
e.printStackTrace（）;
}
}
}
赶上（例外前）
{
ex.printStackTrace（）;
}
}
解决方案
craete基于此示例XML文件
的DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance（）;
DocumentBuilder的docBuilder = docFactory.newDocumentBuilder（）;
//根元素
文档的文档= docBuilder.newDocument（）;
元rootElement的= doc.createElement（订单）;
doc.appendChild（rootElement的）;
//设置属性类
ATTR RATTR = doc.createAttribute（Order_atrribute）;
Rattr.setValue（curtrade）;
rootElement.setAttributeNode（RATTR）;
// companyid元素
元的员工= doc.createElement（companyid）;
rootElement.appendChild（工作人员）;
//缩短方式
// staff.setAttribute（ID，1）;
//名字元素
元素名字= doc.createElement（的OrderItems）;
firstname.appendChild（doc.createTextNode（HII））;
staff.appendChild（名字）;
和写的内容转换成XML文件
的TransformerFactory的TransformerFactory = TransformerFactory.newInstance（）;
变压器变压器= transformerFactory.newTransformer（）;
DOMSource的源=新DOMSource的（文件）;
StreamResult结果=新StreamResult（新文件（this.getFilesDir（）getAbsolutePath（），file.xml））;
//的String = this.getFilesDir（）getAbsolutePath（）;
//输出到控制台进行测试
// StreamResult结果=新StreamResult（的System.out）;
transformer.transform（源，结果）;
按
上传您的文件 DefaultHttpClient的HttpClient =新DefaultHttpClient（）;
HttpPost httppost =新HttpPost（url_context +/orders/order.php）;
字符串文件路径= this.getFilesDir（）getAbsolutePath（）。
文件F =新的文件（文件路径，file.xml）;
// byte []的数据= FileOperator.readBytesFromFile（F）;
字符串的内容= getFileContents（F）;
StringEntity SE =新StringEntity（内容，HTTP.UTF_8）;
se.setContentType（为text / xml）;
httppost.setEntity（SE）;
f.delete（）;
HTT presponse HTT presponse = httpClient.execute（httppost）;
Log.d（xml1，HTT presponse.toString（））;
HttpEntity resEntity = HTT presponse.getEntity（）;
Log.d（XML2，resEntity.toString（））;
字符串RESULT1 = EntityUtils.toString（resEntity）;
Log.d（XML，作家=+ RESULT1）;
梅索德getFileContent是
公共字符串getFileContent（最后文件的文件）抛出IOException异常{
最后的InputStream的InputStream =新的FileInputStream（文件）;
最后的BufferedReader读卡器=新的BufferedReader（新的InputStreamReader（InputStream中））;
最后StringBuilder的StringBuilder的=新的StringBuilder（）;
布尔做= FALSE;
而（！做）{
最后串线= reader.readLine（）;
做=（行== NULL）;
如果（线！= NULL）{
stringBuilder.append（线）;
}
}
reader.close（）;
inputStream.close（）;
返回stringBuilder.toString（）;
}

As i am new to android Please provide me the link of the tutorial to post xml data on the server. I am facing the problem is executing the post request
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();
}
}
解决方案
craete your xml file based on this example
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);
and write the content into xml file
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);
post your file by
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);
methode getFileContent is
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();
}
