java - 如何解决 'HttpHeaders' has private access in 'org.apache.http.HttpHeaders' 错误

Question

我正在尝试使用 RestTemplate 发出 Http 请求，但它一直给我错误:'HttpHeaders' 在 'org.apache.http.HttpHeaders' 中具有私有(private)访问权限

我只是想写这一行:

HttpHeaders headers = new HttpHeaders();

Answer 1

包名错误，为了在使用Spring RestTemplate时添加头，应该使用org.springframework.http.HttpHeaders.HttpHeaders而不是org.apache.http.HttpHeaders 。以下是添加请求 header 的代码片段。

// request resource
HttpHeaders headers = new HttpHeaders();
headers.set("headerName", "headerValue");

HttpEntity entity = new HttpEntity(headers);

ResponseEntity<String> response = restTemplate.exchange("https://example.com", HttpMethod.GET, entity, String.class);
