Java+自定义XML请求

针对多个XML请求 .

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 response = restTemplate.postForEntity(url, entity, String.class);
        if (response.getStatusCode().is2xxSuccessful()) {
            String body = response.getBody();
            String s = subString(body, "<" + methodName + "Result>", "");
            return JSON.parseObject(s);
        }
        return null;
    }

拼接XML请求体

 private String getXmlInfo(String methodName, String params) {
        StringBuilder sb = new StringBuilder();
        sb.append("");
        sb.append("");
        sb.append("");
        sb.append("     <" + methodName + " xmlns='http://www.data86.net/'>");
        sb.append("" + params + "");
        sb.append("     ");
        sb.append(" ");
        sb.append(" ");
        return sb.toString();
    }
    

截取返回体中的内容

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

        
        int strStartIndex = str.indexOf(strStart);
        int strEndIndex = str.indexOf(strEnd);

        
        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";
        }
        
        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 = "***** *****";
        JSONObject login = XMLRequest("Login", url, paramsss);
        return login.get("Guid").toString();
    }
