一、前言
为什么会产生这个需求呢?
我们公司作为乙方,老是被客户追着要一份API文档,当我们把一个 Swagger 文档地址丢给客户的时候。客户还是很不满意,嫌不够正式!!死活坚持要一份 word 文档 。然后领导给了个接口模板,就把这个活交给我了......我去,近10个微服务,几百个接口,这不得要了我的命啊(最后整理出来将近200页的 word 文档)。最后,还是领导有办法:要不我们把Swagger的 json文件转成word文档吧!
一直坚持一句话。作为使用者,人要迁就机器;作为开发者,要机器迁就人。
二、思路
领导提供了一个接口模板,类似下面这样,其实就是一个word的table页。想到 html 可以转 word ,那么问题就变成了 :
1、解析JSON 文件
2、把JSON文件的内容填充进html 的Table中
3、由html直接转成word
几百个接口,一气呵成!如下,还有一个简单的示例,就是请求参数 和 返回值 。怎么处理呢?在程序中写了 HTTP 的请求,封装了需要的参数去执行了一个请求,得到相应的返回值!
三、实现
1、封装对象
按照面向对象的思想,一个接口Table就是一个对象,可变的请求参数和返回参数也封装成一个对象......
public class Table { /** * 大标题 */ private String title; /** * 小标题 */ private String tag; /** * url */ private String url; /** * 响应参数格式 */ private String responseForm; /** * 请求方式 */ private String requestType; /** * 请求体 */ private List<Request> requestList; /** * 返回体 */ private List<Response> responseList; /** * 请求参数 */ private String requestParam; /** * 返回值 */ private String responseParam; public String getTitle() { return title; } public void setTitle(String title) { this.title = title; } public String getTag() { return tag; } public void setTag(String tag) { this.tag = tag; } public String getUrl() { return url; } public void setUrl(String url) { this.url = url; } public String getResponseForm() { return responseForm; } public void setResponseForm(String responseForm) { this.responseForm = responseForm; } public String getRequestType() { return requestType; } public void setRequestType(String requestType) { this.requestType = requestType; } public List<Request> getRequestList() { return requestList; } public void setRequestList(List<Request> requestList) { this.requestList = requestList; } public List<Response> getResponseList() { return responseList; } public void setResponseList(List<Response> responseList) { this.responseList = responseList; } public String getRequestParam() { return requestParam; } public void setRequestParam(String requestParam) { this.requestParam = requestParam; } public String getResponseParam() { return responseParam; } public void setResponseParam(String responseParam) { this.responseParam = responseParam; } }
public class Request { /** * 请求参数 */ private String description; /** * 参数名 */ private String name; /** * 数据类型 */ private String type; /** * 参数类型 */ private String paramType; /** * 是否必填 */ private Boolean require; /** * 说明 */ private String remark; public String getDescription() { return description; } public void setDescription(String description) { this.description = description; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getType() { return type; } public void setType(String type) { this.type = type; } public Boolean getRequire() { return require; } public void setRequire(Boolean require) { this.require = require; } public String getRemark() { return remark; } public void setRemark(String remark) { this.remark = remark; } public String getParamType() { return paramType; } public void setParamType(String paramType) { this.paramType = paramType; } }
public class Response { /** * 返回参数 */ private String description; /** * 参数名 */ private String name; /** * 说明 */ private String remark; public Response(String description, String name, String remark) { this.description = description; this.name = name; this.remark = remark; } public String getDescription() { return description; } public void setDescription(String description) { this.description = description; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getRemark() { return remark; } public void setRemark(String remark) { this.remark = remark; } }
2、解析 json
先来看看Swagger json文件的格式吧!需要注意的是这个 json 文件默认的 host 是没有加 http:// 前缀的,需要我们手动加上,因为程序的HTTP请求不像浏览器一样会自动补上 http:// 的前缀 ......
解析JSON真是一件枯燥的工作,大家可以按照自己想要生成模板的样子修改这边的代码......需要提的是,这里有一点让我纠结了好久。怎么伪造接口的请求参数发送HTTP请求以避免不会抛异常呢?最后还是参考了Swagger的方式,即:如果是 String 类型的参数,就把这个参数置为"string";如果是 Integer 类型的参数,就把这个参数置为 0 ;如果是Double 类型的参数,就置为 0.0 ;如果是其他没办法预见的类型,就全部置为 null;
解析 JSON 用的是Spring推荐的 jackson ,这部分感觉没什么好说的,直接上代码吧!
@Service public class TableServiceImpl implements TableService { @Override public List<Table> tableList() { List<Table> list = new LinkedList(); try { ClassLoader classLoader = TableService.class.getClassLoader(); URL resource = classLoader.getResource("data.json"); Map map = new ObjectMapper().readValue(resource, Map.class); //得到host,用于模拟http请求 String host = String.valueOf(map.get("host")); //解析paths LinkedHashMap<String, LinkedHashMap> paths = (LinkedHashMap) map.get("paths"); if (paths != null) { Iterator<Map.Entry<String, LinkedHashMap>> iterator = paths.entrySet().iterator(); while (iterator.hasNext()) { Table table = new Table(); List<Request> requestList = new LinkedList<Request>(); String requestType = ""; Map.Entry<String, LinkedHashMap> next = iterator.next(); String url = next.getKey();//得到url LinkedHashMap<String, LinkedHashMap> value = next.getValue(); //得到请求方式,输出结果类似为 get/post/delete/put 这样 Set<String> requestTypes = value.keySet(); for (String str : requestTypes) { requestType += str + "/"; } Iterator<Map.Entry<String, LinkedHashMap>> it2 = value.entrySet().iterator(); //解析请求 Map.Entry<String, LinkedHashMap> get = it2.next();//得到get LinkedHashMap getValue = get.getValue(); String title = (String) ((List) getValue.get("tags")).get(0);//得到大标题 String tag = String.valueOf(getValue.get("summary")); //请求体 ArrayList parameters = (ArrayList) getValue.get("parameters"); if (parameters != null && parameters.size() > 0) { for (int i = 0; i < parameters.size(); i++) { Request request = new Request(); LinkedHashMap<String, Object> param = (LinkedHashMap) parameters.get(i); request.setDescription(String.valueOf(param.get("description"))); request.setName(String.valueOf(param.get("name"))); request.setType(String.valueOf(param.get("type"))); request.setParamType(String.valueOf(param.get("in"))); request.setRequire((Boolean) param.get("required")); requestList.add(request); } } //返回体,比较固定 List<Response> responseList = listResponse(); //模拟一次HTTP请求,封装请求体和返回体,如果是Restful的文档可以再补充 if (requestType.contains("post")) { Map<String, String> stringStringMap = toPostBody(requestList); table.setRequestParam(stringStringMap.toString()); String post = NetUtil.post(host + url, stringStringMap); table.setResponseParam(post); } else if (requestType.contains("get")) { String s = toGetHeader(requestList); table.setResponseParam(s); String getStr = NetUtil.get(host + url + s); table.setResponseParam(getStr); } //封装Table table.setTitle(title); table.setUrl(url); table.setTag(tag); table.setResponseForm("application/json"); table.setRequestType(StringUtils.removeEnd(requestType, "/")); table.setRequestList(requestList); table.setResponseList(responseList); list.add(table); } } return list; } catch (IOException e) { e.printStackTrace(); } return null; } //封装返回信息,可能需求不一样,可以自定义 private List<Response> listResponse() { List<Response> responseList = new LinkedList<Response>(); responseList.add(new Response("受影响的行数", "counts", null)); responseList.add(new Response("结果说明信息", "msg", null)); responseList.add(new Response("是否成功", "success", null)); responseList.add(new Response("返回对象", "data", null)); responseList.add(new Response("错误代码", "errCode", null)); return responseList; } //封装post请求体 private Map<String, String> toPostBody(List<Request> list) { Map<String, String> map = new HashMap<>(16); if (list != null && list.size() > 0) { for (Request request : list) { String name = request.getName(); String type = request.getType(); switch (type) { case "string": map.put(name, "string"); break; case "integer": map.put(name, "0"); break; case "double": map.put(name, "0.0"); break; default: map.put(name, "null"); break; } } } return map; } //封装get请求头 private String toGetHeader(List<Request> list) { StringBuffer stringBuffer = new StringBuffer(); if (list != null && list.size() > 0) { for (Request request : list) { String name = request.getName(); String type = request.getType(); switch (type) { case "string": stringBuffer.append(name+"&=string"); break; case "integer": stringBuffer.append(name+"&=0"); break; case "double": stringBuffer.append(name+"&=0.0"); break; default: stringBuffer.append(name+"&=null"); break; } } } String s = stringBuffer.toString(); if ("".equalsIgnoreCase(s)){ return ""; } return "?" + StringUtils.removeStart(s, "&"); } }
3、html 模板
我们需要一个和 Word Table 模板一样的HTML 页面,然后利用JSP的 foreach 遍历后台得到的 List<Table> 集合,一气呵成,生成所有接口......
