Postman使用记录,通过表格动态赋值循环调用接口 - Using CSV and JSON data files in the Postman Collection Runner

1.GET请求,通过导入csv文件来处理
GET http://localhost:8080/web/addstudent?sno={{sno}}&name={{name}}&sex={{sex}}

2.POST请求，通过导入json文件来处理。
示例中的excel表格数据通过http://tools.jb51.net/code/excel_col2json/ 转换成json格式
POST http://localhost:8080/web/addstudent2
{"sno":"{{sno}}","name":"{{name}}","sex":"{{sex}}"} //注意带上双引号，否则入参的请求会报错

Data File 赋值的参数通过"{{参数}}"来实现。

集合运行器让我们导入CSV或JSON文件，然后在HTTP请求和脚本中使用来自数据文件的值。这些变量称为数据变量。要在Postman UI中使用它们，必须遵循与环境或全局变量相同的语法。使用相同的语法可以帮助您使用虚拟环境值在Postman内部测试单个请求。当你运行测试用例集，你不需要改变任何东西。

在点击下方蓝色的 Run按钮之前，可以先点击 箭头所指的 Preivew按钮先预览一下数据的格式是否正确。

//model:
public class Student implements Serializable{
    private static final long serialVersionUID = -339516038496531943L;
    private String sno;
    private String name;
    private String sex;
    public String getSno() {
        return sno;
    }
    public void setSno(String sno) {
        this.sno = sno;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getSex() {
        return sex;
    }
    public void setSex(String sex) {
        this.sex = sex;
    }
}

//controller: (演示功能：通过接口将学号，姓名，性别添加到数据库中)
    @RequestMapping(value = "/addstudent", method = RequestMethod.GET)
    public int saveStudent(String sno,String name,String sex) {
        Student student = new Student();
        student.setSno(sno);
        student.setName(name);
        student.setSex(sex);
        return this.studentService.add(student);
    }

    @RequestMapping(value = "/addstudent2", method = RequestMethod.POST)
    public int saveStudent2(@RequestBody Student student) {
        return this.studentService.add(student);
    }

实际在导入的时候，选择csv或者json文件都可以。以上仅仅是演示两种情况。
