问题描述
限时送ChatGPT账号..我有一个授权服务器 [用 @SpringBootApplication
注释的简单类,@RestController
,@Configuration
,@EnableAuthorizationServer
&oauth2 安全性] 运行在端口 8081
上,工作正常 &使用 POST
方法从 POSTMAN 请求时提供访问令牌以及键值对形式的必要参数,http://localhost:8080/oauth/token
,但是我应该如何在java中实现camel路由通过在body中传递参数来获取访问令牌?
I have an authorization server [Simple Class annotated with @SpringBootApplication
,
@RestController
,@Configuration
,@EnableAuthorizationServer
& oauth2 security] running on port 8081
which works fine & provides the access token when requested from POSTMAN using POST
method along with needful parameters in the form of key value pair,
http://localhost:8080/oauth/token
, but how should i implement the camel route in java to get the access token by passing parameters in body ?

这个问题更多是关于使用 Apache Camel 发送 multipart/form-data
.前段时间我在玩它,并使用自定义处理器解决了它,将标题转换为 multipart/form-data
格式,并使用 Content-Disposition: form-data
.
This question is more about sending multipart/form-data
with Apache Camel. I was playing with it some time ago and solved it with custom Processor, converting headers to multipart/form-data
format with Content-Disposition: form-data
.
这是我的处理器将标头转换为 multipart/form-data
格式:
This is my Processor converting headers to multipart/form-data
format:
public class PrepareMultipartFormData implements Processor {
private String[] multipartHeaders;
public PrepareMultipartFormData(String... multipartHeaders) {
this.multipartHeaders = multipartHeaders;
}
@Override
public void process(Exchange exchange) throws Exception {
addMultipart(exchange.getIn(), multipartHeaders);
}
private static void addMultipart(Message message, String... multipartKeys){
final String boundary = "---------------------------"+RandomStringUtils.randomAlphanumeric(9);
message.setHeader(Exchange.CONTENT_TYPE, "multipart/form-data;boundary="+boundary);
StringBuilder sb = new StringBuilder("--").append(boundary);
for (String key: multipartKeys) {
sb.append("\r\n")
.append("Content-Disposition: form-data; name=\"").append(key).append("\"")
.append("\r\n\r\n")
.append(message.getHeader(key, String.class))
.append("\r\n")
.append("--").append(boundary);
}
message.setBody(sb.toString());
}
}
您需要向 OAuth 请求令牌发送:
HTTP 标头授权标头 - 这是由端点选项指定的标准HTTP组件的一部分authUsername
和 authPassword
Content-Type - 这是添加到我的 PrepareMultipartFormData
处理器
HTTP headers
Authorization header - This is part of standard HTTP component specified by endpoint options authUsername
and authPassword
Content-Type - This is added in my PrepareMultipartFormData
Processor
grant_type用户名密码client_id
最终路线可以这样实现:
(用一些表达式替换常量,以动态设置它.如果您只需要 token
响应,请添加一些解组,因为此路由返回 JSON)
Final route can be implemented in this way:
(Replace constants with some expressions, to set it dynamically. If you need only token
in response, add some unmarshalling, since this route returns JSON)
from("direct:getTokenResponse")
.setHeader(Exchange.HTTP_METHOD, constant("POST"))
.setHeader(Exchange.HTTP_PATH, constant("oauth/token"))
.setHeader("grant_type", constant("password"))
.setHeader("username", constant("admin"))
.setHeader("password", constant("admin1234"))
.setHeader("client_id", constant("spring-security-oauth2-read-write-client"))
.process(new PrepareMultipartFormData("grant_type", "username", "password", "client_id"))
.to("http://localhost:8080?authMethod=Basic&authUsername=oauth-endpoint-username&authPassword=oauth-endpoint-password")
.convertBodyTo(String.class)
.to("log:response");

使用 PrepareMultipartFormData#addMultipart 实现apache/http/entity/mime/MultipartEntityBuilder.html" rel="nofollow noreferrer">MultipartEntityBuilder.
Updating answer to provide a bit shorter implementation of PrepareMultipartFormData#addMultipart
using MultipartEntityBuilder.
private static void addMultipart(Message message, String... multipartKeys) throws Exception{
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
for (String key: multipartKeys) {
builder.addTextBody(key, message.getHeader(key, String.class));
}
HttpEntity resultEntity = builder.build();
message.setHeader(Exchange.CONTENT_TYPE, resultEntity.getContentType().getValue());
message.setBody(resultEntity.getContent());
}
