postman:用postman实现post提交json数据(postman 7.31.1)

一,用postman摸拟js的JSON.stringify方式提交数据到接口:

我们这里看一个例子:用json方式提交用户名和密码后,

接口返回一个jwt的token字符串,

1,headers:

添加一项: Content-Type

取值为: application/json

如图:

2,body标签:

形式选择:raw

格式选择:JSON

如图:

3,提交后可以看到结果:

二,用js实现json格式提交数据的例子:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>使用 jwt 登录页面</title>
</head>
<body>
<div>
    <input type="text" id="userName" name="userName" value="" placeholder="username">
</div>
<div>
    <input type="password" id="password" name="password" value="" placeholder="password">
</div>
<div>
    <input type="button" id="btnSave" onclick="go_login()"  value="登录">
</div>
<script src="https://cdn.bootcss.com/jquery/1.11.3/jquery.js"></script>
<script>
        //登录
        function go_login() {
            var username=$("#userName").val();
            var password=$("#password").val();
            if ($("#userName").val() == "") {
                alert('userName is empty');
                $("#userName").focus();
                return false;
            }
            if ($("#password").val() == "") {
                alert('password is empty');
                $("#password").focus();
                return false;
            }
            var postData = {
                "username":username ,
                "password" : password
            }
            $.ajax({
                cache: true,
                type: "POST",
                url: "/auth/authenticate",
                contentType: "application/json;charset=UTF-8",
                data:JSON.stringify(postData),
                dataType: "json",
                async: false,
                error: function (request) {
                    console.log("Connection error");
                },
                success: function (data) {
                    //save token
                    console.log("data:");
                    console.log(data);
                    if (data.code == 0) {
                        //success
                        alert("success:"+data.msg+";token:"+data.data.token);
                        //save token
                        localStorage.setItem("token",data.data.token);
                    } else {
                        //failed
                        alert("failed:"+data.msg);
                    }
                }
            });
        };
</script>
</body>
</html>

关键的一行代码是:

JSON.stringify(postData)
