我正在尝试使用 Apache Http 从 Java 桌面/独立应用程序获取访问令牌:
StringBuilder sb = new StringBuilder();
sb.append("code").append('=').append(authorization_code)
.append('&').append("client_id").append('=').append(client_id)
.append('&').append("client_secret").append('=').append(client_secret)
.append('&').append("redirect_uri").append('=').append("urn:ietf:wg:oauth:2.0:oob2")
.append('&').append("grant_type").append('=').append("authorization_code");
HttpPost httppost
= new HttpPost("https://accounts.google.com/o/oauth2/token");
httppost.setEntity(new StringEntity(sb.toString()));
System.out.println(httppost.getURI());
System.out.println(new String(
EntityUtils.toByteArray(httppost.getEntity())));
httppost.getEntity().getContent();
HttpClient httpclient = new DefaultHttpClient();
HttpResponse resp = httpclient.execute(httppost);
byte[] ba = EntityUtils.toByteArray(resp.getEntity());
System.out.println(new String(ba));
请求网址为:
https://accounts.google.com/o/oauth2/token
内容是:
code=4/uktjFRIoKS-VTwADJjO6vSYV3ZyU.Qop5zb7BIj0bOl05ti8ZT3bH57rDdgI
&client_id=128871852795.apps.googleusercontent.com
&client_secret=***********************
&redirect_uri=urn:ietf:wg:oauth:2.0:oob2
&grant_type=authorization_code
我得到:
{
"error" : "invalid_request"
}
我阅读了其他类似的 SO 问题,但它并没有解决我的问题。
我究竟做错了什么?
