Java 卷曲请求-更改为RestTemplate-无正文错误

我有一个curl命令，它工作得很好，但是当我在RestTemplate中尝试它时，会出现错误

卷曲：

弹簧座模板

    restTemplate = new RestTemplate();
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    headers.setAccept(Collections.singletonList(MediaType.APPLICATION_JSON));

    Map<String, Object> map = new HashMap<>();
    map.put("body", "{\"refresh_token\": \"eyJhbGciOiJSUzUxMiIsInR5cCI6IkpXVCIsIng1dCI6IndKZlQ2NHpqemQxWk4yS1duX3FYSmpvOHByMCIsImtpZCI6Im9yYWtleSJ9.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.UCkScWFn8d3pupwAxilT8T-m6Rf8fgZ8ge9OZvWZbZ-4eCVCPyHeI8A1a2QV0_iZhjwHaITNTzCZ4Eydfkm-mZuCa-PLY63HJhWLzTGlbaYsWRVtHaLF58F6spZ106T6T3ZDvQVIsiQ9845ruG_1ib0vKV_57X_CcVB4XZktYvA\"}");

    HttpEntity<Map<String, Object>> entity = new HttpEntity<>(map, headers);

    String urlString = "https://api.example.com/v1/tokens/accessToken";
    String response = restTemplate.postForObject(urlString, entity, String.class);

所以，如何正确地将上述curl转换为RestTemplate，以避免服务器错误和正文错误。Curl命令工作正常。

试试这个

    restTemplate = new RestTemplate();
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    headers.setAccept(singletonList(MediaType.APPLICATION_JSON));
    HttpEntity<String> entity = 
             new HttpEntity<>("{\"refresh_token\": \"eyJhb...\"}", headers);

restTemplate=新的restTemplate（）；
HttpHeaders=新的HttpHeaders（）；
headers.setContentType（MediaType.APPLICATION_JSON）；
setAccept（singletonList（MediaType.APPLICATION_JSON））；
HttpEntity实体=
新的HttpEntity（“{\”刷新\“：\”eyJhb…\“}”，标题）；

正如您正确注意到的，您应该使用：

map.put("refresh_token", "eyJhbGci...". 

---

但是你有401只是因为你传递了另一个令牌（检查diff-cURL与java代码版本）

map.put（“刷新令牌”，“eyJhbGci…”当我这样做时，我得到这个错误：401未经授权：[没有人]你应该使用：map.put（“刷新令牌”，“eyJhbGci…”。你有401是因为你传递了另一个令牌（检查diff-cURL与java代码版本）谢谢star67，我使用新的有效刷新代码和它的逻辑。我得到了访问令牌。祝您愉快。请发布您的答案以被接受谢谢，但它也不起作用。原因：org.springframework.web.client.HttpClientErrorException$Unauthorized:401 Unauthorized:[无正文]

    restTemplate = new RestTemplate();
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    headers.setAccept(singletonList(MediaType.APPLICATION_JSON));
    HttpEntity<String> entity = 
             new HttpEntity<>("{\"refresh_token\": \"eyJhb...\"}", headers);

map.put("refresh_token", "eyJhbGci...".
