我的表格如下:

<form name="signupForm" id="signupForm" method="POST" ng-submit="create()">
            <input type="hidden" name="username" id="username" value="mtest">
            <input type="text" placeholder="Account name" name="webid" ng-model="account.webid" ng-focus="isFocused" ng-blur="isFocused = false"><br>
            <input type="text" placeholder="Full name" name="name" ng-model="account.name"><br>
            <input type="text" placeholder="Email" name="email" ng-model="email"><br>
            <input type="text" placeholder="Picture URL" name="pictureURL" ng-model="account.pictureURL"><br>
            <keygen id="spkac" name="spkac" challenge="randomchars" keytype="rsa" form="signupForm" hidden>
            <br>
            <input type="submit" id="submit" value="Submit">
</form>

数据按如下方式传递给POST:

$http({
          method: 'POST', 
          url: uri,
          data: $("#signupForm").serialize(),
          headers: {
            'Content-Type': 'application/x-www-form-urlencoded',
            'Accept': 'application/x-x509-user-cert'
          },
          withCredentials: true
        }).

一旦我提交表格以发送POST http请求,我就会得到$("#signupForm").serialize(),如下所示:

"username=mtest&webid=mtest.databox.me%2Fprofile%2Fcard%23me&name=M+Test&email=mtest%40test.com&pictureURL=picURL&spkac="

为什么keygen元素总是空的?我在做什么事吗?

任何答案都表示赞赏,提前谢谢。

解决!

因此,准备HTTP请求以执行此操作不会因某些原因而起作用。相反,需要设置表单操作并立即提交表单以便发送keygen。这是解决方案:

模板中的操作是参数化的:

    <form name="signupForm" id="signupForm" method="POST" action="{{actionUrl}}">
     ...
    <input type="submit" id="btnSubmit" value="Submit" ng-click="completeForm()">

并且控制器设置操作并按如下方式提交表单:

$scope.completeForm = function () {
        $scope.actionUrl = "https://" + document.getElementById("username").value + "...";
        document.getElementById("signupForm").submit();     
};
