用flask搭建一个测试数据生成器(v1.1)

在v1.0版本中实现了"页面点击按钮,生成对应测试数据"的功能,但是在操作页面只有一个按钮,没有提供任何参数(即没有涉及到参数在前后端传递,只是单纯的触发请求);

这次在前端页面给每个按钮加一个参数,用来控制生成测试数据的个数,更改后的页面大概如下

 所以接下来要做如下改造工作:

  1. 改造html模版,在每个按钮后添加一个输入框(添加input标签);
  2. 改造视图函数,例如phone()函数,使它能够接收一个参数,控制生成数据的个数;
  3. 改造js代码,使它能够接收input标签输入的值;

一、修改 base.html 和 base.css

为每个按钮添加一个输入框,另外调整下整体布局,base.html 代码如下

 1 <!DOCTYPE html>
 2 <html lang="en">
 3 <head>
 4     <meta charset="UTF-8">
 5     <title>Title</title>
 6     <link rel="stylesheet" href="{{ url_for('static', filename='base.css') }}" type="text/css">
 7     <script type="text/javascript" src="{{ url_for('static', filename='jquery-3.5.1.js') }}"></script>
 8 </head>
 9 <body>
10     <div class="left">
11     <div class="b1">
12         <form method="get" action="">
13             <button  type="button" id="b01">手机号码</button>
14             <label>
15             <input type="text" name="phone_num" id="pnone_num" value="" placeholder="请输入个数">
16         </label>
17         </form>
18 
19     </div>
20 
21     <div class="b1">
22         <form method="get" action="">
23             <button  type="button" id="b02">身份证ID</button>
24             <label>
25             <input type="text" name="card_id" id="id_num" value="" placeholder="请输入个数">
26         </label>
27         </form>
28     </div>
29 
30     <div class="b1"><button type="button" id="b03">人名</button>
31         <label>
32             <input type="text" name="name" value="" placeholder="请输入个数">
33         </label>
34     </div>
35     <div class="b1"><button type="button" id="b04">一段文字</button></div>
36     <div class="b1"><button type="button" id="b05">特殊字符</button>
37         <label for=""><select name="special" id="select">
38             <option value="5">5个</option>
39             <option value="10">10个</option>
40             <option value="20">20个</option>
41         </select></label>
42     </div>
43 
44     <div class="b1"><button style="background-color:darkred;color: #fcfcfc" type="button" id="b07">清空输出</button></div>
45     </div>
46 
47     <div ><label for="result"></label><textarea class="textera" name="" id="result" cols="103" rows="20"></textarea></div>
48 
49    
50 </body>
51 </html>
View Code

 base.css代码如下

.b1 {
    /*float: left;*/
    /*display: inline;*/
    /*background-color: #7ED321;*/
    margin-right: 20px;
    margin-left: 50px;
    margin-top: 20px;
}

div .left {
    float:left;
    color: #f00;
    border: 2px;
}

input .w {
    width: 1px;
}

.textera {
    position:absolute;
    left: 350px;
    top: 20px;
    background-color: #f1f1d1;
}

二、改造视图函数

因为之前当触发按钮时,触发的get请求如下

http://127.0.0.1:5000/phone

现在要加一个参数,假设参数名为num,希望触发的get请求变为如下形式

http://127.0.0.1:5000/phone?num=

后台路由如果想接收这种形式的参数,例如上面的num,则可以通过下面这种方式

request.args.get("num")

以phone()视图函数为例,改造后如下

def create_phone(num):
    """生成电话"""

    phones = [fake.phone_number() for _ in range(int(num))] 
 
    return " ".join(phones)


@app.route('/phone', methods=['POST', 'GET'])
def phone():

    num = request.args.get("num")
    if num == "":  # 如果接收到的num为空,则默认传5
        data = create_phone(5)
    else:
        data = create_phone(num)
    return data

三、改造js代码,使它能够接收input标签输入的值

在实现过程中,一直在想如何从前端获取input标签输入的num参数值,传递给后端路由

经过多方查找资料,还是从jquery入手,可以先用js获取input标签的值,再拼接到url中,如下

 $(document).ready(function(){
          $("#b01").click(function(){
              var num = $('input[name=phone_num]').val()  // 获取phone输入框的值
              console.log(num)
          htmlobj=$.ajax({url:"http://10.237.4.83:5000/phone?num="+num,async:false}); // 把参数num的值拼接到url中
          $("#result").html(htmlobj.responseText);
          });
        });

get请求也可以这样写
$(document).ready(function(){
$("#b02").click(function(){
var num = $('input[id=id_num]').val()
var data = { //定义data参数值
"num": num
}
console.log(num)
htmlobj=$.ajax({
type: 'get',
url:"http://10.237.4.83:5000/id",
data: data,
async:false});
$("#result").html(htmlobj.responseText);
});
});

最后看一下实现效果:

综上,代码改造全部完成,完整代码如下:
