获取OAUTH2令牌

本文介绍了获取OAUTH2令牌的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试从我们的IDM服务器中检索OAUTH2令牌-我尝试了几种基本示例，但所有示例均返回200状态且未包含任何代码.我可以通过邮递员使用以下标头来毫无困难地做到这一点:

I'm trying to retrieve a OAUTH2 token from our IDM server - I've tried several flavors of rudimentary examples, but all of them return a 200 status with no code included. I can do it with no trouble via postman, using a header of:

Content-Type application/x-www-form-urlencoded

...，然后发送client_id，redirect_uri和代码参数.我回来的东西看起来像这样:

... and sending the client_id, redirect_uri and code parameters. I get something back that looks like this:

{ "access_token": "abcd...", "token_type": "bearer", "expires_in": 3600 }

这是超级基本代码，旨在做的只是看我是否可以抓住令牌(此时):

Here's the super rudimentary code intended to do no more than see if I can grab the token (at this point):

public class Service { public String getToken() { String client_id = "f2e8..."; String redirect_uri = "mysite/"; String code = "AAAAAA..."; form = new Form(); form.param("client_id", client_id); form.param("code", code); form.param("redirect_uri", redirect_uri); JerseyClientBuilder jerseyClientBuilder = new JerseyClientBuilder(); JerseyWebTarget jerseyWebTarget = jerseyClientBuilder.build().target("token-source-site/"); Response response = jerseyWebTarget.request().post(Entity.form(form)); return response.toString(); } }

但是我得到的只是:

InboundJaxrsResponse{context=ClientResponse{method=POST, uri=token-source-site/, status=200, reason=OK}}

是否有任何关于Postman可能在做的事情的想法，认为我的代码不是?

Any thoughts on what Postman might be doing that my code isn't?

推荐答案

仅在Response上调用toString()时，它不会显示在响应正文中.您需要通过调用Response#readEntity从其中提取主体.

It's not going to show to the response body when you just call toString() on the Response. You need to extract the body from it by calling Response#readEntity.

但是即使尝试将其提取为字符串，您仍然有必须解析该字符串的问题.最好的办法是为令牌响应创建一个POJO

But even trying to extract it to a String, you have the problem of still having to parse the string. Best thing to do is to create a POJO for the token response

public class AccessTokenResponse { @JsonProperty("access_token") private String accessToken; @JsonProperty("token_type") private String tokenType; @JsonProperty("expires_in") private long expiresIn; // getters and setters }

那你就可以做

Response response = jerseyWebTarget.request().post(Entity.form(form)); return response.readEntity(AccessTokenResponse.class);

使方法返回AccessTokenResponse，因此客户端也可以访问其他属性.

Make the method return AccessTokenResponse, so the client has access to the other properties also.

要使其正常工作，您将需要具有Jackson提供商的依赖项

For this to work, you will need to have the Jackson provider dependency
