postman高級應用（5）-Pre-requestScript發送請求

1. 發送get請求
   
   按 Ctrl+C 復制代碼

    
                var host = pm.environment.get("host"); 
   const csrfTokenServlet = {
    url: `https://${host}/{path}?csrfType=test`,
    method: 'GET'
   }; 
                pm.sendRequest(csrfTokenServlet, (err, response) => {
    if (err) {
    console.log(err);
    } else {
    pm.environment.set("csrfToken", response.json()['data']);
    console.log(response.json()['data'])
    }
   }); 
               

2. 發送post請求
   

   # content-type/x-www-form-urlencoded
   
   var host = pm.environment.get("host"); 
   
   var data = {
   "organCode":"10000065",
   }
   const postRequest = {
     url: `https://${host}/${path}`,
     method: 'POST',
     header:'Content-Type:application/x-www-form-urlencoded',
     body: {
       mode: 'x-www-form-urlencoded',
       raw: "organCode=10000062"
     }};
   pm.sendRequest(postRequest, (err, response) => {
       if (err) {
           console.log(err);
       } else {
           console.log(response.json());
       }
   });
   
   或者
   
   var host = pm.environment.get("host"); 
   
   var data = {
   "organCode":"10000065",
   }
   const postRequest = {
     url: `https://${host}/${path}`,
     method: 'POST',
     header:'Content-Type:application/x-www-form-urlencoded',
     body: {
       mode: 'urlencoded',
       urlencoded: "organCode=10000062"
     }};
   pm.sendRequest(postRequest, (err, response) => {
       if (err) {
           console.log(err);
       } else {
           console.log(response.json());
       }
   });
   
   # content-type/json
   var data = {
   "key1":"value1",
   "key2":"value2",}
   const echoPostRequest = {
     url: 'http://ip:port/XXX,
     method: 'POST',
     header:'Content-Type:application/json',
     body: {
       mode: 'raw',
       raw: JSON.stringify(data)
     }};
   pm.sendRequest(echoPostRequest, function (err, res) {
       console.log(res.json());
   });

   postman(六)：詳解在Pre-request Script中如何執行請求
   

   postman 在pre-request中發送application/x-www-form-urlencoded 格式表單
   

   postman pre-request-script 操作方法記錄

3. 實例：請求中需要引用另一條請求結果中的id字段，現在prerequest-script中發送請求如下：1.先定義隨機函數 2.定義發送請求設置 3.設置隨機數 4.發送請求並設置需要引用的變量

   function randomFrom(lowerValue,upperValue)
   {
   return Math.floor(Math.random() * (upperValue - lowerValue + 1) + lowerValue);
   }
   var settings = {
   "url": pm.environment.get("server")+"/column/search?device_id=6148CE69-070B-490B-ACCC-0658B3042457&Open-Platform=WEB&userId="+pm.environment.get("user_id")+"&token="+pm.environment.get("token")+"&limit=15&offset=0&column=RECOMMEND&curSelectId=&columnBannerId=0",
   "method": "GET",
   "header": {
   "access_token": pm.environment.get("token"),
   "user_id": pm.environment.get("user_id"),
   "User-Agent": "ABCMainMoudle/2.1.1 (iPhone; iOS 13.2.2; Scale/2.00)"}
   }
   var i=randomFrom(1,20)
   pm.sendRequest(settings, (err, response) => {
   if (err) {
   console.log(err);
   } else {
   console.log(response.json());
   var res=response.json().data;
   var id_de=res.items[i]["id"]
   pm.environment.set("id", JSON.stringify(id_de));
   }
   });

    再在params中引用id，id={{id}}
