## 逻辑流
### 1、添加逻辑流

### 2、进入逻辑流脚本编辑

- request：用于获取请求参数
获取get参数示例：`String state = request.getParameter("state");`
获取post参数示例：`String body = this.parseRequst(request);`
```javascript
//取body参数
    public static String parseRequst(HttpServletRequest request){
        String body = "";
        try {
            request.setCharacterEncoding("utf-8");
            ServletInputStream inputStream = request.getInputStream();

BufferedReader br = new BufferedReader(new InputStreamReader(inputStream, "utf-8")); //防止乱码
            while (true) {
                String info = br.readLine();
                if (info == null) {
                    break;
                }
                if (body == null || "".equals(body)) {
                    body = info;
                } else {
                    body += info;
                }
            }
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return body;
    }  
```

- response：响应值（groovy优先，groovy未传response时，则以中间层为准）
示例（注：groovy有response时，logicflow参数必传，否则接口返回状态始终为500）：
```javascript
String stringJson = "{\"logicflow\":true,\"status\":200,\"dataPack\":{\"FUSER\":\"测试\",\"FNAME\":\"张三\"}}";
ResponseUtil.responseData(response,"text/plain;charset=UTF-8",stringJson);
```
