作者：qq_42607375
这篇文章主要为大家详细介绍了Springboot发送post请求的几种方式,文中的示例代码讲解详细,对我们学习或工作有一定的帮助,感兴趣的小伙伴可以了解一下
请求体为json形式
/***
url:请求路径
content: 请求参数，为json字符串
token: 请求认证token,放置在请求头里
*/
public ResponseEntity<String> callApi(String url, String content, String token) {
RestTemplate restTemplate = new RestTemplate();
// 设置请求头，指定Content-Type为application/json
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
// 添加Authorization头
headers.add(Constants.AUTHORIZATION, Constants.TOKEN_PREFIX + shareToken);
// 创建HttpEntity，将JSON参数和请求头添加到请求中
HttpEntity<String> requestEntity = new HttpEntity<>(content, headers);
// 发送POST请求
ResponseEntity<String> responseEntity = restTemplate.exchange(url, HttpMethod.POST, requestEntity, String.class);
return responseEntity;
}
请求体为x-www-form-urlencoded
public ResponseEntity<String> callApi(String url, String content, String token) {
RestTemplate restTemplate = new RestTemplate();
// 设置请求头，指定Content-Type为application/json
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
// 添加Authorization头
headers.add(Constants.AUTHORIZATION, Constants.TOKEN_PREFIX + shareToken);
JSONObject jsonObject = JSONObject.parseObject(content);
// 将解析后的 JSON 对象转换为 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;
}
请求体为form-data
public ResponseEntity<String> callApi(String url, String content, String token) {
RestTemplate restTemplate = new RestTemplate();
// 设置请求头，指定Content-Type为application/json
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.MULTIPART_FORM_DATA_VALUE);
// 添加Authorization头
headers.add(Constants.AUTHORIZATION, Constants.TOKEN_PREFIX + shareToken);
JSONObject jsonObject = JSONObject.parseObject(content);
// 将解析后的 JSON 对象转换为 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;
}
