    @RequestMapping("/redirect") //获取授权码时的回调地址，使用获得的授权码获取access_token
    public Map get(@RequestParam(value = "code") String code){
        OkHttpClient httpClient=new OkHttpClient();

        RequestBody requestBody=new FormBody.Builder()
                .add("grant_type","authorization_code")
                .add("client","user")

                .build();

        Request request=new Request.Builder()
                .url(accessTokenUri)
                .post(requestBody)
                .addHeader("Authorization","Basic dXNlcjoxMjM0NTY=")
                .build();

        Map result=null;

        try {
            Response response=httpClient.newCall(request).execute();
            System.out.println(response);

            ObjectMapper objectMapper=new ObjectMapper();
            result=objectMapper.readValue(Objects.requireNonNull(response.body()).string(),Map.class);

            System.out.println("access_token："+result.get("access_token"));
            System.out.println("token_type："+result.get("token_type"));
            System.out.println("refresh_token："+result.get("refresh_token"));
            System.out.println("expires_in："+result.get("expires_in"));
            System.out.println("scope："+result.get("scope"));
        }catch (Exception e){
            System.out.println(e.getMessage());
        }

        return result;
    }
}

说明：获取授权码后需要设置redirect_uri，且需要与获取授权码时的redirect_uri地址一致，否则会报错

"error": "invalid_grant","error_description": "Redirect URI mismatch."

*************************

使用测试

*********************

获取授权码

localhost:8081/oauth/authorize?client_id=user&response_type=code&redirect_uri=http//localhost:8082/redirect

                   

client的属性autoApprove：false手动授权，true自动授权

                   

获取授权后跳转到回调地址：http://localhost:8082/redirect

        

*********************

refresh token操作

localhost:8081/oauth/token

查询参数：grant_type=refresh_token&refresh_token=86ba104c-7d96-4f0b-bcde-161cb12dbb4e

header：key：Authorization，value：Basic dXNlcjoxMjM0NTY=

        

        

*********************

获取数据

localhsot:8082/hello

header：key：Authorization，value：bearer 36c6a366-bfa1-462d-bf27-8c88c0893c45

        

localhost:8082/hello2

header：key：Authorization，value：bearer 36c6a366-bfa1-462d-bf27-8c88c0893c45
