怎么了伙计们
我在raspberry pi上有一个返回字符串的简单api（我们称之为api-a）

@RestController
@CrossOrigin("*")
public class SimpleController{

    @GetMapping("/text")
    public String getText(){
        return "text";
    }
}

我还有一个api，我试图从上一个api获取文本（我们称之为api-b）

@RestController
@CrossOrigin(origins = "*")
public class SecondController{
...
@GetMapping("/gettext")
    public String getTextFromRaspberry(){
        RestTemplate rest = new RestTemplate();
        ResponseEntity<String> response = rest.exchange(
                "http://192.168.55.109/text",
                HttpMethod.GET,
                HttpEntity.EMPTY,
                String.class);
        return response.getBody();
    }
...

这是我的安全配置

@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .anyRequest().permitAll()
                .and()
                .sessionManagement()
                    .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
                .csrf().disable()
                .cors();
    }
}

和cors配置

@Configuration
public class CorsConfigurer implements WebMvcConfigurer {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry
                .addMapping("/**")
                .allowedMethods("GET", "POST", "PUT", "PATCH", "DELETE", "OPTIONS")
                .allowCredentials(true)
                .allowedOrigins("*")
                .allowedHeaders("*");
    }
}

当我在raspberry pi上运行api-a，在localhost上运行api-b时，一切都正常。
但是当我在heroku上部署api-b时，它会得到一个异常
