英文:
Spring boot returns a 404 when calling another API internally
问题
I have a spring boot API that internally has to call another API and just "forward" the request.
private String APIRoot;
public APIInteractionController() {
this.APIRoot = "<API root here, not showing it because it's private>";
}
//test if calling API works
@GetMapping("/test")
public String testAPI(){
logCallAPI(APIRoot);
String result = callAPI(APIRoot);
return result;
}
private String callAPI(String uri){
RestTemplate restTemplate = new RestTemplate();
String result = restTemplate.getForObject(uri, String.class);
return result;
}
private void logCallAPI(String uri){
System.out.println("call API:\nuri: " + uri);
}
When I call the endpoint on my spring boot app, the logger statement gets outputted in the console, but in Postman, I just get a 404 even though when I call the API on itself it just returns "hello world" as the root just returns a test string.
Why is this, and how can I resolve this.

这个StackOverflow答案描述了如何为Spring RestTemplate启用HTTP wire日志记录。启用后，您应该能够在日志中看到实际调用的URL，从而找出为什么会收到404返回代码以及它是从哪里调用的。
