400发送HTTP发布请求以从身份验证代码获取令牌时出现错误请求?

我正在尝试访问account.google.com，以从使用HTTP发布请求收到的授权代码中获取令牌.

I am trying to access accounts.google.com to get token from authorization code received using HTTP post request.

    var searchurl = "https://accounts.google.com/o/oauth2/token";

    $.ajax({
        dataType: "json",
        url:searchurl,
        data: {code:auth_code, client_id:'client_id', client_secret:'secret', redirect_uri:'http%3A%2F%2Flocalhost:8085%2FGmailIntegration%2FgetAuthResponse1.jsp', grant_type:'authorization_code'},
        type:"Post",
        contentType:"application/x-www-form-urlencoded",
        success:function(data) {
            alert(data);
        },
        error: function(jqXHR, exception) {
            console.log(jqXHR);

        }
    });

错误:

这是我正在使用的文档: Web服务器收到授权代码后，可以将授权代码交换为访问令牌和刷新令牌.该请求是一个HTTPs帖子，并包含以下参数:

here is the document which i am using: After the web server receives the authorization code, it may exchange the authorization code for an access token and a refresh token. This request is an HTTPs post, and includes the following parameters:

字段说明 代码初始请求返回的授权代码 client_id在应用程序注册期间获得的client_id client_secret在应用程序注册期间获取的客户端机密 redirect_uri向应用程序注册的URI grant_type如OAuth 2.0规范中所定义，此字段必须包含authorization_code的值 实际的请求可能如下所示:
