這篇文章主要為大家詳細(xì)介紹了Springboot發(fā)送post請(qǐng)求的幾種方式,文中的示例代碼講解詳細(xì),對(duì)我們學(xué)習(xí)或工作有一定的幫助,感興趣的小伙伴可以了解一下

請(qǐng)求體為json形式

/***
url:請(qǐng)求路徑
content: 請(qǐng)求參數(shù)，為json字符串
token: 請(qǐng)求認(rèn)證token,放置在請(qǐng)求頭里
*/
public ResponseEntity<String> callApi(String url,  String content, String token) {
        RestTemplate restTemplate = new RestTemplate();
        // 設(shè)置請(qǐng)求頭，指定Content-Type為application/json
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);
        // 添加Authorization頭
        headers.add(Constants.AUTHORIZATION, Constants.TOKEN_PREFIX + shareToken);
        // 創(chuàng)建HttpEntity，將JSON參數(shù)和請(qǐng)求頭添加到請(qǐng)求中
        HttpEntity<String> requestEntity = new HttpEntity<>(content, headers);
        // 發(fā)送POST請(qǐng)求
        ResponseEntity<String> responseEntity = restTemplate.exchange(url, HttpMethod.POST, requestEntity, String.class);
        return responseEntity;
    }

請(qǐng)求體為x-www-form-urlencoded

public ResponseEntity<String> callApi(String url,  String content, String token) {
        RestTemplate restTemplate = new RestTemplate();
        // 設(shè)置請(qǐng)求頭，指定Content-Type為application/json
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
        // 添加Authorization頭
        headers.add(Constants.AUTHORIZATION, Constants.TOKEN_PREFIX + shareToken);
        JSONObject jsonObject = JSONObject.parseObject(content);
         // 將解析后的 JSON 對(duì)象轉(zhuǎn)換為 MultiValueMap
         MultiValueMap<String, Object> formData = new LinkedMultiValueMap<>();
         for (String key : jsonObject.keySet()) {
             formData.add(key, jsonObject.get(key));
         }
         HttpEntity<MultiValueMap<String, Object>> requestEntity = new HttpEntity<>(formData, headers);
         responseEntity = restTemplate.exchange(url, HttpMethod.POST, requestEntity, String.class);
        return responseEntity;
    }

請(qǐng)求體為form-data

public ResponseEntity<String> callApi(String url,  String content, String token) {
        RestTemplate restTemplate = new RestTemplate();
        // 設(shè)置請(qǐng)求頭，指定Content-Type為application/json
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.MULTIPART_FORM_DATA_VALUE);
        // 添加Authorization頭
        headers.add(Constants.AUTHORIZATION, Constants.TOKEN_PREFIX + shareToken);
        JSONObject jsonObject = JSONObject.parseObject(content);
            // 將解析后的 JSON 對(duì)象轉(zhuǎn)換為 MultiValueMap
            MultiValueMap<String, Object> formData = new LinkedMultiValueMap<>();
            for (String key : jsonObject.keySet()) {
                formData.add(key, jsonObject.get(key));
            }
            HttpEntity<MultiValueMap<String, Object>> requestEntity = new HttpEntity<>(formData, headers);
            responseEntity = restTemplate.exchange(url, HttpMethod.POST, requestEntity, String.class);
        return responseEntity;
    }
