项目需求：

输入参数描述是从后台查出来的。

解决：
返回的json：

{
    "count": 1,
    "resultList": [
        {
            "code": "s_x2001_2013",
            "cnName": "国家信息中心_HelloWorld",
            "inType": "10",
            "serviceDesc": "HelloWorld",
            "cataId": "3",
            "cata_title": "国家数据",
            "version": "V1.0",
            "registerId": "sys",
            "register": "system",
            "deptId": "x2001",
            "dept": "国家信息中心",
            "registerDate": "2017-12-22 13:17:59.0",
            "publishDate": "2017-11-16 10:41:25.0",
            "applyCount": null,
            "browseCount": null,
            "status": "8",
            "validityDate": "2017-12-02 09:26:14.0",
            "serviceType": "java,11",
            "methods": [
                {
                    "id": "5",
                    "code": "s_x2001_2013",
                    "methodName": "sayHi",
                    "methodDes": "sayHi",
                    "methodType": "POST",
                    "inputParams": [
                        {
                            "id": "1",
                            "methodId": "5",
                            "name": "text",
                            "position": "body",
                            "type": "1,1",
                            "isRequired": "1",
                            "defaultValue": "",
                            "describe": "text"
                        }
                    ],
                    "responseType": "XML",
                    "outputSuccess": "success1",
                    "outputFailure": "failure1"
                }]
              }
        ]
}

后台代码：

// 调nation_data_admin工程，根据code查服务详情
result = MyHttpClient.getMethod(url);
//服务详情页面去除inputparams的id和methodId
JSONObject jsonObject=new JSONObject(result);
JSONArray jsonResultArray= (JSONArray)jsonObject.get("resultList");
for(int i=0;i<jsonResultArray.length();i++){
    JSONObject jsonResultData=(JSONObject)jsonResultArray.get(i);
    JSONArray jsonMethodsArray=(JSONArray)jsonResultData.get("methods");
    for(int j=0;j<jsonMethodsArray.length();j++){                   
        JSONObject jsonMethodData=(JSONObject)jsonMethodsArray.get(j);
        JSONArray jsonParamArray=(JSONArray)jsonMethodData.get("inputParams");
        for(int k=0;k<jsonParamArray.length();k++){
            JSONObject jsonParamData=(JSONObject)jsonParamArray.get(k);
            jsonParamData.remove("id");
            jsonParamData.remove("methodId");
        }
    }
}
