最近再做接口自动化测试，其中有几个方法比较重要

1.获取http状态码

/** 返回接口状态码

**/

public staticString getHttpCode(String url) {

String code= null;try{

URL u= newURL(url);

URLConnection uc=u.openConnection();

HttpURLConnection huc=(HttpURLConnection)uc;

code= newInteger(huc.getResponseCode()).toString();

}catch(Exception e) {//TODO Auto-generated catch block

e.printStackTrace();

}returncode;

}

2.获取json

/** 3个参数

**/

public staticString getJson(String base_url, String para1, String value1, String para2, String value2, String para3, String value3) {

String url= base_url + para1 + "=" + value1 + "&"

+ para2 + "=" + value2 + "&"

+ para3 + "=" +value3;

String result= "";

String code=getHttpCode(url);if(!code.startsWith("2")) {

result= "*******接口的状态码为："+code+"*******"+url;

}else{

StringBuilder json= newStringBuilder();try{

URL u= newURL(url);

URLConnection uc=u.openConnection();

BufferedReader bd= new BufferedReader(new InputStreamReader(uc.getInputStream(),"UTF-8"));

String s= null;while((s=bd.readLine())!=null) {

json.append(s);

}

bd.close();

}catch(Exception e) {//TODO Auto-generated catch block

e.printStackTrace();

}

result=json.toString();

}returnresult;

}

3.获取json中的某个值，如{"a","1"}

public staticString getJsonValue(String json, String name){

String s= null;

JSONObject jobj=JSONObject.fromObject(json);//JSONObject jobj = JSONObject.fromObject("{‘total‘:‘0‘,‘message‘:‘用户编号不能为空‘,‘data‘:‘‘,‘code‘:‘2‘,‘rows‘:‘‘}");

Iterator it =jobj.keys();while(it.hasNext()){

String key=it.next().toString();

String value=jobj.getString(key);if(key.equals(name)) {

s=value.trim();

}

}returns;

}

4.获取双重json中第二维json的某个值，如{"a","1",{"b","1"}}

public staticString getJsonValue(String json,String jdate, String name){

JSONObject jobj=JSONObject.fromObject(json);

JSONObject dataList=jobj.getJSONObject(jdate);

String balance=dataList.getString(name);returnbalance;

}

5.获取json中包含数组中的第N个json，如{"a","1","b","[{"a2","1"},{"b2","1"}]"}

/*获取jsonArray*/

public static String getJsonArray(String json, String arr_name, intindex) {

JSONObject jobj=JSONObject.fromObject(json);

JSONArray childs=jobj.getJSONArray(arr_name);

JSONObject job=childs.getJSONObject(index);returnjob.toString();

}

6.连接数据库

public static ListconnectSqlList(String sql,String userNum, String col) {

String url= "jdbc:mysql://172.16.30.209:3306/a_test";

String name= "gmsd";

Connection con= null;

ResultSet rs= null;

String rssql= null;

List list = new ArrayList();try{

Class.forName("com.mysql.jdbc.Driver").newInstance();

con= DriverManager.getConnection(url,name,"dlnu1234");

PreparedStatement pst=con.prepareStatement(sql);

pst.setString(1, userNum);

rs=pst.executeQuery();while(rs.next()) {

rssql=rs.getString(col);

list.add(rssql);

}

}catch(Exception e) {//TODO Auto-generated catch block

e.printStackTrace();

}finally{try{

rs.close();

con.close();

}catch(SQLException e) {//TODO Auto-generated catch block

e.printStackTrace();

}

}returnlist;

}
