PostMan使用案例（1）

postman客户端下载地址：https://www.getpostman.com/apps

1.接口请求的使用
第一步：将接口放URL中，选取请求方式，

第二步：填入请求头信息，参数，如果是post请求，则将参数内容放在body中。
当请求参数值从环境变量中取时，用{{}}括起来，PS：当有环境变量时，记得在右上角选择你定义的那个环境变量，不然会读取环境变量失败



第三步：修改环境变量
点击右上角的眼睛图标，可以查看当前环境变量的值，点击Edit，可以对环境变量进行编辑


第四步：验证或获取返回数据
我验证的接口的返回值：

{"code":0,"message":null,"data":{"id":123456,"loginName":"654321","nickname":null,"realName":"王丹杨","gender":null,"birthday":null,"phone":"15150477114","email":null,"countryId":null,"provinceId":836,"cityId":876,"countyId":null,"address":null,"idCard":null,"avatar":null,"sourceFrom":null,"status":1,"openIdQQ":null,"deviceToken":"AnAm3NhdSgw-uxSOlCd6olHT-Fu21l7RGCNBcOnFNHDj","appPush":null,"schoolStudentInfoBO":{"id":123456,"schoolId":2772,"schoolName":"【测试】测试学校（初中）","jkCode":"654321","studentName":"王丹杨","gender":4,"birthday":null,"idCard":null,"studentNo":"909090","studentCode":"1710106","studentType":2,"phone":"15150477114","email":null,"address":null,"bound":true,"studentId":123456,"clzssesInfo":[{"id":59685,"schoolId":2772,"gradeId":4646,"baseGradeValue":2,"schoolYear":2018,"clzssName":"1班","clzssType":1,"fullName":"1班","sort":2,"finished":null,"status":null,"gradeName":"初二","studentClassSubjects":[{"id":111640,"schoolId":2772,"baseSubjectValue":1,"gradeId":4646,"schoolSubjectName":"数学","sort":1},{"id":111641,"schoolId":2772,"baseSubjectValue":2,"gradeId":4646,"schoolSubjectName":"语文","sort":2},{"id":111642,"schoolId":2772,"baseSubjectValue":3,"gradeId":4646,"schoolSubjectName":"英语","sort":3},{"id":111643,"schoolId":2772,"baseSubjectValue":4,"gradeId":4646,"schoolSubjectName":"物理","sort":4},{"id":111644,"schoolId":2772,"baseSubjectValue":5,"gradeId":4646,"schoolSubjectName":"化学","sort":5},{"id":111645,"schoolId":2772,"baseSubjectValue":6,"gradeId":4646,"schoolSubjectName":"生物","sort":6},{"id":111646,"schoolId":2772,"baseSubjectValue":7,"gradeId":4646,"schoolSubjectName":"政治","sort":7},{"id":111647,"schoolId":2772,"baseSubjectValue":8,"gradeId":4646,"schoolSubjectName":"历史","sort":8},{"id":111648,"schoolId":2772,"baseSubjectValue":9,"gradeId":4646,"schoolSubjectName":"地理","sort":9},{"id":111649,"schoolId":2772,"baseSubjectValue":10,"gradeId":4646,"schoolSubjectName":"信息","sort":10}]}]}},"total":null}

需要更好看的查看请使用json转换
我要获得clzssesInfo里面的数据并保存到全局环境变量中，在下个接口使用这些数据。

var jsonData = JSON.parse(responseBody);
//学生id
postman.setGlobalVariable("studentid", jsonData.data.id);
//get city id
postman.setGlobalVariable("cityId", jsonData.data.cityId);
//get schoolid
postman.setGlobalVariable("schoolId", jsonData.data.schoolStudentInfoBO.schoolId);
//get jikenum
postman.setGlobalVariable("jkCode", jsonData.data.schoolStudentInfoBO.jkCode);

var classinfo = jsonData.data.schoolStudentInfoBO.clzssesInfo;
//classinfo返回是个OBJECT类型的数组，拿下标为0的值
var obj = classinfo[0];
postman.setGlobalVariable("baseGradeValue",obj.baseGradeValue);
//get classid
postman.setGlobalVariable("clzssid",obj.id);
//get gradeid
postman.setGlobalVariable("gradeId",obj.gradeId);

验证接口返回是否是200，

//判断执行结果
var message = jsonData.message;
if (responseCode.code === 200) ;
tests["接口执行成功，code返回200"] = responseCode.code ===200;

if (message === "null");
tests["接口执行成功，message为null"] = responseCode.code ===200;
if(message != "null");
tests["接口执行失败，错误信息"+message];

第五步：Collection使用

添加Collection，将需要一起run的API添加到一个collection中，并取见名知意的名字。

PS：

每个接口之间跑的顺序可以在Tests定义，最后一个接口一定要定义终止程序，否则会进入死循环。

// the next api
postman.setNextRequest("收藏题目");
//是一个终止程序作用
postman.setNextRequest("null");

使用技巧：
打开console控制台快捷键：Ctrl+Alt+C，方便debug脚本
