Oauth 2.0 400发送http post请求以从身份验证代码获取令牌时请求错误？

我正在尝试访问accounts.google.com，从使用HTTP post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"

以下是我正在使用的文件： 在web服务器接收到授权码之后，它可以将授权码交换为访问令牌和刷新令牌。此请求是HTTPs post，包括以下参数：

字段描述 code从初始请求返回的授权代码 客户端id在应用程序注册期间获得的客户端id client_secret在应用程序注册期间获得的客户机密 重定向\u uri向应用程序注册的uri 根据OAuth 2.0规范中定义的grant_类型，此字段必须包含AUTHORITION_代码的值 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

对此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

我让它工作了。。我正在为那些深陷其中的人分享代码：

$.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);
        }
    });

但现在我有了新的问题。url得到200个OK响应，但我根本没有得到响应

谢谢。这帮了我的忙。我忘了在内容类型中添加'charset=utf-8'，它解决了我的问题。如果你解决了问题，请发布解决方案。谷歌服务器需要Json。文档中的错误。发送json而不是表单编码。但保持内容类型为形式-encoded@pamu你能发布一个完整的答案吗。我尝试发送json。但是没有运气。
