一、正常json参数的请求方式

代码片段如下：

String result = HttpUtil.post(URL_DEFAULT+"d38e4357cb96dce5", JSONUtil.parseObj(Dict.create()
                    .set("fileName", cityTransitMapParams.getFileName())
                    .set("appKey",cityTransitMapParams.getAppKey())
                    .set("signature",cityTransitMapParams.getSignature())
                    .set("timestamp",cityTransitMapParams.getTimesTampStr())
                    .set("servertype",cityTransitMapParams.getServertype())
                    .set("proxyToken",proxyToken)
            ).toString());

二、form-data请求参数的请求方式

代码片段如下：

HttpRequest post = HttpUtil.createPost(URL_DEFAULT + "/login"); 

Map<String, Object> paramMap = new HashMap<>();  
paramMap.put("userName",cityTransitMapLoginParams.getUserName()); 
paramMap.put("password",cityTransitMapLoginParams.getPassword()); 
paramMap.put("clientId",cityTransitMapLoginParams.getClientId()); 
paramMap.put("serviceId",cityTransitMapLoginParams.getServiceId()); 

post.form(paramMap); 
String result = post.execute().body();
