[Java知识库]SpringBoot 请求外部api

使用RestTemplate实现操作

RestTemplate template =new (RestTemplate );
ResponseEntity<String> entity=template.getForEntity(url, String.class);
switch (entity.getStatusCodeValue()){
    case 200:
        return entity.getBody();
    case 500:
        return "Error:500";
    default:
        return "Error:Unknow";
}
