Java 通过post将数据从android发送到node.js？

我使用nodejs作为服务器，java（android）作为客户端，通过post成功地将数据从android发送到节点。但是我的问题是，android发送的数据（字符串）由空格和新行（回车）组成，它在节点上收到，但字符已更改

例如，我从android发送这个字符串

Hello
I learn android

字符串send to node和received，但我在node中得到了它

Hello%0AI+learn+android

我使用此代码在android中将字符串发送到节点

 public void btnOnClick(){
      String text= URLEncoder.encode(editText.getText().toString(), "utf-8"); //I get from editText and convert to utf-8
      sendToNode(text);

}


public void sendToNode(String text){
    try {                       

                 HttpClient httpclient = new DefaultHttpClient();
                 HttpPost httppost = new HttpPost("http://myDomain.com:8888/");
                 UrlEncodedFormEntity form;
                 try {
                     Log.i("kirim ke node isitextAsli ",text);
                     List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();


                     nameValuePairs.add(new BasicNameValuePair("datanah",text));
                     form=new UrlEncodedFormEntity(nameValuePairs,"UTF-8");
                     httppost.setEntity(form);

                     HttpResponse response = httpclient.execute(httppost);


                     Log.i("HTTP Post", "Response from server node = " + response.getStatusLine().getReasonPhrase() + "  Code = " + response.getStatusLine().getStatusCode());
                 } catch (ClientProtocolException e) {
                     Log.e("HTTP Post", "Protocol error = " + e.toString());
                 } catch (IOException e) {
                     Log.e("HTTP Post", "IO error = " + e.toString());
       }
}

我如何解决我的问题

请帮助，谢谢。

字符串是URL编码的，正如您在代码中明确要求的那样（并且需要定期发布）。在服务器上解码

要在服务器端对其进行解码，请执行以下操作：

var querystring = require('querystring'); 
querystring.unescape(data.replace(/\+/g, " "));

下面是编码和解码的示例，您希望在服务器部分进行解码

        String encoded;  
        try {  
            encoded = URLEncoder.encode(input, "UTF-8");  

        System.out.println("URL-encoded by client with UTF-8: " + encoded);  

        String incorrectDecoded = URLDecoder.decode(encoded, "ISO-8859-1");  
        System.out.println("Then URL-decoded by server with ISO-8859-1: " + incorrectDecoded);  

        String correctDecoded = URLDecoder.decode(encoded, "UTF-8");  
        System.out.println("Server should URL-decode with UTF-8: " + correctDecoded);  
        } catch (UnsupportedEncodingException e) {  
            // TODO Auto-generated catch block  
            e.printStackTrace();  
        }

是否检查“文本”中的值？它的值是什么？是的，我知道，值是Hello%0AI+learn+android，因为我将文本编码为utfyou need res.on（“数据”…如何在服务器中解码？我尝试过使用文本手动代码。替换（/++/，“”）它不起作用。Node.js有一个内置函数来做这件事。请尝试

var querystring=require（'querystring'））

querystring.unescape（数据）；

@FMontano：我尝试过在某些情况下工作，只有新行（enter）可以工作，但空格仍然是“+”而不是“@ltvie，尝试

querystring.unescape（data.replace（/\+/g）”；

        String encoded;  
        try {  
            encoded = URLEncoder.encode(input, "UTF-8");  

        System.out.println("URL-encoded by client with UTF-8: " + encoded);  

        String incorrectDecoded = URLDecoder.decode(encoded, "ISO-8859-1");  
        System.out.println("Then URL-decoded by server with ISO-8859-1: " + incorrectDecoded);  

        String correctDecoded = URLDecoder.decode(encoded, "UTF-8");  
        System.out.println("Server should URL-decode with UTF-8: " + correctDecoded);  
        } catch (UnsupportedEncodingException e) {  
            // TODO Auto-generated catch block  
            e.printStackTrace();  
        }
