如this blog post中所述，我们可以使用ProtobufHttpMessageConverter序列化/反序列化Protobuf消息。使用基本身份验证时，如果我选择带有protobuf消息转换器的JSON媒体类型，我可以使用preemptive auth或不使用，它并不重要。但是，如果我选择protobuf媒体类型，我必须使用抢先身份验证否则它不起作用，即服务器按预期返回未经授权的响应，但随后返回基本身份验证响应似乎没有被处理。但是，当我打开抢占式身份验证时，即立即发送基本身份验证响应时，它会按预期工作。尽管如此，这对我来说似乎很奇怪。有人知道为什么吗？
您将在下面找到重现问题的示例代码。例如，只需使用REST Client访问Web服务。
@SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
@Bean
ProtobufHttpMessageConverter protobufHttpMessageConverter() {
return new ProtobufHttpMessageConverter();
}
}
@Configuration
@EnableWebSecurity
class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth)
throws Exception {
auth.inMemoryAuthentication()
.withUser("test").password("test").roles("USER");
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/**").hasRole("USER")
.and()
.httpBasic()
.and()
.sessionManagement().sessionCreationPolicy(
SessionCreationPolicy.STATELESS)
.and()
.csrf().disable();
}
}
@RestController
class CustomerRestController {
@RequestMapping("/")
Data.Customer customer() {
return customer(5, "Toto");
}
private Data.Customer customer(int id, String f) {
return Data.Customer.newBuilder()
.setId(id)
.setName(f)
.build();
}
}
Protobuf消息data.proto：
package demo;
message Customer {
optional int32 id = 1;
optional string name = 2;
}
这是不时使用preemptive auth并使用以下请求标头获得的日志：＆＃34;接受：application / x-protobuf＆＃34;。您可以注意到在未经授权的响应之后没有任何反应（应该处理基本的身份验证响应）。

答案 0 :(得分：2)
这似乎是Spring Boot中的一个问题。我创建了spring-projects/spring-boot/issues#2827。
发生了什么事？
这是因为BasicErrorController正在创建ResponseEntity<Map<String, Object>>。 ProtobufHttpMessageConverter尝试撰写正文时，ProtobufHttpMessageConverter only supports writing protobuf Message objects
解决问题
可以通过创建自定义Controller来处理错误来解决此问题。例如：
package demo;
option java_package = "demo";
option java_outer_classname = "Data";
message MapFieldEntry {
required string key = 1;
required string value = 2;
}
message Error {
repeated MapFieldEntry errors = 1;
}
生成相应的Java类。然后创建一个控制器：
package demo;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.web.ErrorAttributes;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.context.request.RequestAttributes;
import org.springframework.web.context.request.ServletRequestAttributes;
import demo.Data.Error.Builder;
import demo.Data.MapFieldEntry;
/**

@Controller
public class ErrorController {
private final ErrorAttributes errorAttributes;
@Autowired
public ErrorController(ErrorAttributes errorAttributes) {
this.errorAttributes = errorAttributes;
}
@RequestMapping(value = "/error", produces = "application/x-protobuf")
@ResponseBody
public ResponseEntity<Data.Error> error(HttpServletRequest request) {
Map<String, Object> body = getErrorAttributes(request, getTraceParameter(request));
Builder errorsBuilder = Data.Error.newBuilder();
for(Map.Entry<String, Object> error : body.entrySet()) {
demo.Data.MapFieldEntry.Builder entryBuilder = MapFieldEntry
.newBuilder()
.setKey(error.getKey())
.setValue(String.valueOf(error.getValue()));
errorsBuilder.addErrors(entryBuilder.build());
}
Data.Error errors = errorsBuilder.build();
HttpStatus status = getStatus(request);
return new ResponseEntity<Data.Error>(errors, status);
}
private boolean getTraceParameter(HttpServletRequest request) {
String parameter = request.getParameter("trace");
if (parameter == null) {
return false;
}
return !"false".equals(parameter.toLowerCase());
}
private Map<String, Object> getErrorAttributes(HttpServletRequest request,
boolean includeStackTrace) {
RequestAttributes requestAttributes = new ServletRequestAttributes(request);
return this.errorAttributes.getErrorAttributes(requestAttributes,
includeStackTrace);
}
private HttpStatus getStatus(HttpServletRequest request) {
Integer statusCode = (Integer) request
.getAttribute("javax.servlet.error.status_code");
if (statusCode != null) {
try {
return HttpStatus.valueOf(statusCode);
}
catch (Exception ex) {
}
}
return HttpStatus.INTERNAL_SERVER_ERROR;
}
}
