SpringBoot发送HTTP请求拦截器

通过restTemplate发送的http请求会被拦截，方便开发调试，正式环境尽量别用。

    public ClientHttpResponse intercept(HttpRequest request, byte[] body,
                                        ClientHttpRequestExecution execution) throws IOException {
        logRequest(request, body);
        ClientHttpResponse response = execution.execute(request, body);
//        logResponse(response);
        return response;
    }

    private void logRequest(HttpRequest request, byte[] body) {
        log.info("Request URI: " + request.getURI());
        log.info("Method: " + request.getMethod());
        log.info("Headers: " + request.getHeaders());
        if (body.length > 0) {
            String requestBody = new String(body, StandardCharsets.UTF_8);
            log.info("Request Body: " + requestBody);
        }
    }

    private void logResponse(ClientHttpResponse response) throws IOException {
        log.info("Response Status Code: " + response.getStatusCode());
        log.info("Response Headers: " + response.getHeaders());

        StringBuilder inputStringBuilder = new StringBuilder();
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(response.getBody(), StandardCharsets.UTF_8));
        String line = bufferedReader.readLine();
        while (line != null) {
            inputStringBuilder.append(line);
            inputStringBuilder.append('\n');
            line = bufferedReader.readLine();
        }
        log.info("Response Body: " + inputStringBuilder.toString());
    }
}
