Android httpclient接收xml乱码问题解决方法
因为字符编码的问题，害我折腾了两个小时。以下是代码，大家看一下就明白了。
String url = "http://www.google.com/ig/api?weather=,,,31174165,121433841"; DefaultHttpClient client = new DefaultHttpClient(); HttpUriRequest req = new HttpGet(url); HttpResponse resp = client.execute(req); HttpEntity ent = resp.getEntity(); int status = resp.getStatusLine().getStatusCode(); if(L.Debug) { L.d("" + status); } // 若状态码为 200 ，则表示OK if (status == HttpStatus.SC_OK) { //String result = EntityUtils.toString(ent); if(L.Debug) { //L.d(result); } InputStream stream = ent.getContent(); BufferedReader br = new BufferedReader(new InputStreamReader(stream, "utf-8")); DocumentBuilder b = DocumentBuilderFactory.newInstance() .newDocumentBuilder(); String xmlString = ""; for(String temp = br.readLine(); temp != null;xmlString += temp ,temp = br.readLine()); // 去除字符串中的换行符，制表符，回车符。 xmlString = xmlString.replaceAll("/n|/t|/r", ""); InputStream stream2 = new ByteArrayInputStream(xmlString.getBytes()); Document d = b.parse(new InputSource(stream2)); NodeList n = d.getElementsByTagName("forecast_conditions"); String tips = ""; tips += n.item(0).getChildNodes().item(0).getAttributes() .item(0).getNodeValue(); if(L.Debug) { L.d("" + tips ); L.d("" + n.item(0).getChildNodes().getLength()); //L.Toast(tips, this); } br.close(); stream.close(); stream2.close(); }
关键是这一行代码
BufferedReader br = new BufferedReader(new InputStreamReader(stream, "utf-8"));
将接收的流放入buffer里，处理成utf-8的编码（如果还是乱码，那请改为gb2312或者gbk）
方法二
String url = "http://www.google.com/ig/api?weather=,,,31174165,121433841"; DefaultHttpClient client = new DefaultHttpClient(); HttpUriRequest req = new HttpGet(url); HttpResponse resp = client.execute(req); HttpEntity ent = resp.getEntity(); int status = resp.getStatusLine().getStatusCode(); // If the status is equal to 200 ，that is OK if (status == HttpStatus.SC_OK) { String result = EntityUtils.toString(ent); if(L.Debug) { L.testCharset(result); } // Encode utf-8 to iso-8859-1 result = new String(result.getBytes("ISO-8859-1"), "UTF-8"); DocumentBuilder b = DocumentBuilderFactory.newInstance() .newDocumentBuilder(); String xmlString = result; // Remove the newline,tabs and return characters from string xmlString = xmlString.replaceAll("/n|/t|/r", ""); InputStream stream = new ByteArrayInputStream(xmlString.getBytes()); Document d = b.parse(new InputSource(stream)); getWeatherBean(d); stream.close(); }
// 以下是测试字符编码的 public static void testCharset(String datastr){ try { String temp = new String(datastr.getBytes(), "GBK"); Log.v("TestCharset","****** getBytes() -> GBK ******/n"+temp); temp = new String(datastr.getBytes("GBK"), "UTF-8"); Log.v("TestCharset","****** GBK -> UTF-8 *******/n"+temp); temp = new String(datastr.getBytes("GBK"), "ISO-8859-1"); Log.v("TestCharset","****** GBK -> ISO-8859-1 *******/n"+temp); temp = new String(datastr.getBytes("ISO-8859-1"), "UTF-8"); Log.v("TestCharset","****** ISO-8859-1 -> UTF-8 *******/n"+temp); temp = new String(datastr.getBytes("ISO-8859-1"), "GBK"); Log.v("TestCharset","****** ISO-8859-1 -> GBK *******/n"+temp); temp = new String(datastr.getBytes("UTF-8"), "GBK"); Log.v("TestCharset","****** UTF-8 -> GBK *******/n"+temp); temp = new String(datastr.getBytes("UTF-8"), "ISO-8859-1"); Log.v("TestCharset","****** UTF-8 -> ISO-8859-1 *******/n"+temp); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } }
先用testCharset这个方法，测试哪一种编码没有出现乱码，再修改result = new String(result.getBytes("ISO-8859-1"), "UTF-8");里面对应的编码。
