发送http post请求以从身份验证代码获取令牌时出现400错误请求？

Question

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

    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：

"NetworkError: 400 Bad Request - https://accounts.google.com/o/oauth2/token?
 code=4/PlKII3f0vsPUhl1QNIUXkiIhlfGA.sq9lFf-oCiIcXE-sT2ZLcbRFnpEphQI&client_id={clientid}   
 &client_secret={secret}&redirect_uri=https://oauth2-login-
 demo.appspot.com/code&grant_type=authorization_code"

这是我正在使用的文档： Web 服务器收到授权码后，可以用授权码交换访问令牌和刷新令牌。该请求是一个 HTTPS 帖子，包含以下参数：

字段说明 code 初始请求返回的授权码 client_id 应用注册时获取的client_id client_secret 应用注册时获取的客户端秘钥 redirect_uri 向应用程序注册的 URI grant_type 按照 OAuth 2.0 规范中的定义，该字段必须包含一个值 authorization_code 实际请求可能如下所示：

POST /o/oauth2/token HTTP/1.1
Host: accounts.google.com
Content-Type: application/x-www-form-urlencoded

code=4/P7q7W91a-oMsCeLvIaQm6bTrgtp7&
client_id=8819981768.apps.googleusercontent.com&
client_secret={client_secret}&
redirect_uri=https://oauth2-login-demo.appspot.com/code&
grant_type=authorization_code

对该请求的成功响应包含以下字段：

Field   Description
access_token    The token that can be sent to a Google API
refresh_token   A token that may be used to obtain a new access token. Refresh tokens are valid until the user revokes access. This field is only present if access_type=offline is included in the authorization code request.
expires_in  The remaining lifetime on the access token
token_type  Indicates the type of token returned. At this time, this field will always have the value Bearer

我得到了这个工作..我正在为那些坚持这个的人分享代码：

$.ajax({
        dataType: "json",
        url:searchurl,
        data: {code:code, client_id:'clientid', client_secret:'secret', redirect_uri:'http://localhost:8085/GmailIntegration/getAuthResponse.jsp', grant_type:'authorization_code'},
        type:"POST",
        contentType:"application/x-www-form-urlencoded; charset=utf-8",
        crossDomain:true,
        cache : true, 
        success:function(data) {
            alert(data);
        },
        error: function(jqXHR, exception, errorstr) {
            console.log(jqXHR);
            alert(errorstr);
        }
    });

但现在我有新问题。 url 得到 200 OK 响应，但我根本没有得到响应
