Java+自定义XML请求

针对多个XML请求 .

1. 发起请求方法

    public JSONObject XMLRequest(String methodName, String url, String paramsss) throws JsonProcessingException {
        RestTemplate restTemplate = new RestTemplate();
        String xmlInfo = getXmlInfo(methodName, paramsss);
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.TEXT_XML);
        HttpEntity entity = new HttpEntity(xmlInfo, headers);
        ResponseEntity<String> response = restTemplate.postForEntity(url, entity, String.class);
        if (response.getStatusCode().is2xxSuccessful()) {
            String body = response.getBody();
            String s = subString(body, "<" + methodName + "Result>", "</" + methodName + "Result>");
            return JSON.parseObject(s);
        }
        return null;
    }

2. 拼接XML请求体

 private String getXmlInfo(String methodName, String params) {
        StringBuilder sb = new StringBuilder();
        sb.append("<?xml version='1.0' encoding='UTF-8'?>");
        sb.append("<soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/' >");
        sb.append("<soap:Body>");
        sb.append("     <" + methodName + " xmlns='http://www.data86.net/'>");
        sb.append("" + params + "");
        sb.append("     </" + methodName + ">");
        sb.append(" </soap:Body>");
        sb.append(" </soap:Envelope>");
        return sb.toString();
    }
    

3. 截取返回体中的内容

 public String subString(String str, String strStart, String strEnd) {

        /* 找出指定的2个字符在 该字符串里面的 位置 */
        int strStartIndex = str.indexOf(strStart);
        int strEndIndex = str.indexOf(strEnd);

        /* index 为负数 即表示该字符串中 没有该字符 */
        if (strStartIndex < 0) {
            return "字符串 :---->" + str + "<---- 中不存在 " + strStart + ", 无法截取目标字符串";
        }
        if (strEndIndex < 0) {
            return "字符串 :---->" + str + "<---- 中不存在 " + strEnd + ", 无法截取目标字符串";
        }
        /* 开始截取 */
        String result = str.substring(strStartIndex, strEndIndex).substring(strStart.length());
        return result;
    }

eg:`

  public String LYHLogin() throws JsonProcessingException {
        String url = "http://121.89.178.60/WebServices/UserAdminService.asmx";
        String paramsss = "<LoginName>*****</LoginName> <LoginPwd>*****</LoginPwd>";
        JSONObject login = XMLRequest("Login", url, paramsss);
        return login.get("Guid").toString();
    }
