[开发测试]Springboot RestTemplate发送带请求头header的get请求报错 Postman 同样的参数没有报错的问题

最初代码

String fileId = "fileId";
String token = "token";
String thirdToken = URLEncoder.encode(token, "UTF-8");
String baseStr = "baseStr";
String oauthSignature = "oauthSignature";
log.info("baseStr:{};oauthSignature:{}", baseStr, oauthSignature);
HttpHeaders headers = new HttpHeaders();
headers.add("baseStr", baseStr);
headers.add("oauthSignature", oauthSignature);
HttpEntity<String> httpEntity = new HttpEntity<String>(headers);
String url = params.getTokenCheckUrl() + "?fileId=" + fileId + "&token=" + thirdToken;
ResponseEntity<String> rsStr = restTemplate.getForEntity(url, String.class, httpEntity);

返回报错

调用--token验证,返回结果=rsStr:<200,{"resultCode":"1003","resultMsg":"账号不存在"}>

打开postman

?研究了一下午，发现实际问题是：

RestTemplate发送请求时 自动对参数进行urlencode的问题

修正后代码

String fileId = "fileId";
String token = "token";
String thirdToken = URLEncoder.encode(token, "UTF-8");
String baseStr = "baseStr";
String oauthSignature = "oauthSignature";
log.info("baseStr:{};oauthSignature:{}", baseStr, oauthSignature);
HttpHeaders headers = new HttpHeaders();
headers.add("baseStr", baseStr);
headers.add("oauthSignature", oauthSignature);
HttpEntity<String> httpEntity = new HttpEntity<String>(headers);
String url = params.getTokenCheckUrl() + "?fileId=" + fileId + "&token=" + thirdToken;
// 通过UriComponentsBuilder创建URI对象，这样RestTemplate不会自动进行urlencode
UriComponentsBuilder uriComponentsBuilder = UriComponentsBuilder.fromHttpUrl(url);
URI uri = uriComponentsBuilder.build(true).toUri();
ResponseEntity<String> rsStr = restTemplate.exchange(uri, HttpMethod.GET, httpEntity, String.class);

返回值

调用--token验证,返回结果=rsStr:<200,{"resultCode":"200","resultMsg":"正常"}>
