restTemplate 发送post请求，如何传递数组参数（没有key，只有一个数组的value）？

Question

如下写法，会报错
Required type:HttpEntity<Map<String, String>>
Provided:HttpEntity<Map<String, String>[]>
接口提供方要求不能上传key，只能传递一个数组

    public static String sendPOSTArrRequest(String url, Map<String, String> []params ) {
        log.info("url:"+url);
        log.info("params:"+params);
        RestTemplate client = new RestTemplate();
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);
        HttpEntity<Map<String, String>> r = new HttpEntity<>(params, headers);
        String data= client.postForObject(url, r, String.class);
        return data;
    }

Answer 1

从request对象中根据name去获取就行了

Answer 2

这得看你server怎么接啊
