Question

从我正在尝试构建的单个页面应用程序访问外部api时遇到问题。

我可以使用用户名和密码从Postman登录，然后我获得了一个AuthenticationTicket，我可以用于第二次请求的个人数据。

当我尝试从应用程序登录时，我得到了“No'Access-Control-Allow-Origin'标题出现在请求的资源上。”

我无法使用jsonp，因为它必须发布logindata？！

        $.ajax
        ({
          beforeSend: function (x) {
          x.setRequestHeader('Authorization', 'Basic Username=x&Password=y');
        },
        type: "GET",
        url: "https://test.com/api/login/",
        dataType: 'json',
        async: false,
        success: function () {
            alert('you're in!');
        }

    });

Answer 1

尝试使用JSONP的数据类型：

 dataType: 'jsonp',

Answer 2

当然，C＃修复了这笔交易。

        WebRequest req = WebRequest.Create(@"https://url.com/api/login/?param=value&param2=value");
        req.Method = "GET";
        req.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes("Username:Password"));
        HttpWebResponse resp = req.GetResponse() as HttpWebResponse;
