angularjs 的$http.jsonp请求报错，代码如下：

data = {
    a:A,
    b:B,
    c:C,
}
$http.jsonp('url',data).success(function(res){
    console.log(res);
}).error(function(err){
    console.log(err);//控制台打印fasle
})
并报错:Uncaught SyntaxError: Invalid or Unexpected token  url（请求链接）

点击这个链接，拿到数据，在json在线校验中校验，发现B字段中有换行，但是用链接在浏览器中访问也没发现有换行。联系后台，后台说自己入库的时候没有换行符，我前端也拿不到数据，没办法处理，这种情况还有可能是啥原因，应该怎么解决?

Thank you for the invitation. I didn’t see the address. There should be something wrong with the returned data format.
You can open https://www.w3schools.com/js/... in the browser, then use the developer tools to view the Network panel to view the HTTP information.

Example of using XMLHttpRequest object to request data

<!DOCTYPE html>
<html lang="en" ng-app="myapp">

    <script src="https://cdn.bootcss.com/angular.js/1.6.3/angular.min.js"></script>
</head>
<body ng-app="myapp">
<p ng-controller="AppCtrl">
    <h4>Users List</h4>
    <ul>
        <li ng-repeat="member in members">
            <p>
                ID：<span>{{member.id}}</span>
                Name: <span>{{member.login}}</span>

        </li>
    </ul>

<script type="text/javascript">
