一: 请求URL
public JSONObject HttpPostFromWorklight(String requestParm, String xslFileName, String strURL) { System.out.println("strURL=" + strURL); System.out.println("请求参数:" + requestParm); ResultNew resultNew = new ResultNew(); JSONObject json = new JSONObject(); try { URL url = new URL(strURL);// 创建连接 HttpURLConnection connection = (HttpURLConnection) url.openConnection(); connection.setDoOutput(true); connection.setDoInput(true); connection.setUseCaches(false); connection.setInstanceFollowRedirects(true); connection.setRequestMethod("POST");// 设置请求方式 connection.setRequestProperty("Accept", "text/xml; charset=utf-8");// 设置接收数据的格式 connection.setRequestProperty("Content-Type", "text/xml; charset=utf-8");// 设置发送数据的格式 connection.connect(); OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream(), "UTF-8");// utf-8编码 out.append(requestParm); out.flush(); out.close(); // 读取响应 int length = (int) connection.getContentLength();// 获取长度 InputStream is = connection.getInputStream(); if (length != -1) { byte[] data = new byte[length]; byte[] temp = new byte[512]; int readLen = 0; int destPos = 0; while ((readLen = is.read(temp)) > 0) { System.arraycopy(temp, 0, data, destPos, readLen); destPos += readLen; } String result = new String(data, "UTF-8"); System.out.println("RE:" + result); String src = returnXml(result, xslFileName, "utf-8"); //System.out.println("src:" + src); JSONObject jsonObject = JSON.parseObject(src); //System.out.println("json:" + jsonObject.getString("Items")); resultNew.setStatusReason("OK"); resultNew.setIsSuccessful(true); resultNew.setStatusCode(connection.getResponseCode()); json = (JSONObject) JSONObject.toJSON(resultNew); // 判断json if (jsonObject.getString("Items").startsWith("[")) { json.put("Items", jsonObject.getJSONArray("Items")); } else if (jsonObject.getString("Items").startsWith("{")) { json.put("Items", jsonObject.getJSONObject("Items")); } //System.out.println("JSONObject:" + json); } } catch (Exception e) { // TODO: handle exception e.printStackTrace(); } return json; }
二: xml通过xsl转换
/** * 转换文件(xml通过xsl转换) * @param xml 转换文件 * @param xsl 转换模板 * @param encoding 字符编码 * @return String 返回转换后的xml字符串 * @throws Exception */ public static String returnXml(String xml, String xsl, String encoding) throws Exception { String xslname = CRMService.class.getResource("/").getPath() + "xslFile/" + xsl; System.out.println("xslname:" + xslname); // 获取字符串输入流 StringWriter stringWriter = new StringWriter(); // 获取打印输出流,并设置输出为字符流形式 PrintWriter printWriter = new PrintWriter(stringWriter); // 根据输入的String,获取XML字符串是输入源 Source srcSource = new StreamSource(new ByteArrayInputStream(xml.getBytes(encoding))); // 设置转换结果输出为打印流 Result destResult = new StreamResult(printWriter); // 获取转换模板 // ClassLoader cl = CRMService.class.getClassLoader(); // InputStream is = cl.getResourceAsStream(xsl); File file = new File(xslname); InputStream is = new FileInputStream(file); Source xslSource = new StreamSource(is); // 创建转换工厂 TransformerFactory transFact = TransformerFactory.newInstance(); // 创建转换对象 Transformer trans = transFact.newTransformer(xslSource); // 实行转换 trans.transform(srcSource, destResult); // 把转换结果赋值到 返回的字符串中 String xmlParsed = stringWriter.toString(); // 关闭打印流 printWriter.close(); return xmlParsed; }
