Question

为了从xwiki Rest API获取Json Content，我使用了RestTemplate的方法RestTemplate.exchange（..），但是我找到了404找不到的错误。 Uri包含％2520而不是％20。

这是我的代码：

public static void main(String[] args) throws IOException{   
    private static final String link = "http://swininducasa02.ptx.fr.sopra:8080/xwiki-enterprise-web-8.4.5/rest/wikis/xwiki/spaces/Main/spaces/PIC/spaces/Serveur%20de%20virtualisation/spaces/Serveur%20de%20Marcoussis/spaces/choix/spaces/SGBFV/pages/WebHome";
    String plainCreds = "user:passwd";
    byte[] plainCredsBytes = plainCreds.getBytes();
    byte[] base64CredsBytes = Base64.encodeBase64(plainCredsBytes);
    String base64Creds = new String(base64CredsBytes);
    HttpHeaders headers = new HttpHeaders();
    headers.add("Authorization", "Basic " + base64Creds);
    headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
    headers.setContentType(MediaType.APPLICATION_JSON_UTF8);

    RestTemplate restTemplate = new RestTemplate();
    System.out.println("Begin /GET request!");
    HttpEntity<String> request = new HttpEntity<>(headers);
    ResponseEntity<String> response = restTemplate.exchange(link+ "?media=json", HttpMethod.GET, request, String.class);
    Map<String, String> map = new ObjectMapper().readValue(response.getBody(), Map.class);
    System.out.println( map.get("content"));
}

我搜索过＆amp;我发现问题涉及Content-Type。我尝试了以下所有行，但它仍无效。

headers.add（ “内容类型”，MediaType.APPLICATION_JSON_UTF8_VALUE）;

headers.setContentType(MediaType.APPLICATION_JSON_UTF8);
UriComponents uriComponents = UriComponentsBuilder.fromPath(link).build(true);
URI uri= uriComponents.toUri();

以下是我想要访问的链接：

但我的要求是：

http://swininducasa02.ptx.fr.sopra:8080/xwiki-enterprise-web-8.4.5/rest/wikis/xwiki/spaces/Main/spaces/PIC/spaces/Serveur%2520de%2520virtualisation/spaces/Serveur%2520de%2520Marcoussis/spaces/choix/spaces/SGBFV/pages/WebHome?media=json

角色％20变为％2520。我使用交换，因为我必须设置Auth标头

拜托，你能帮助我吗？

exchange(...)第二次对您的URI进行编码。尝试使用UriComponentsBuilder.build(true)构建URI（true表示您的URI已经编码）。我在你的帖子中看到你说你试过了，但看起来你把它转换成字符串时把它转换成exchange()这可能导致它第二次被编码。

UriComponents uriComponents = UriComponentsBuilder.fromPath(link).queryParam("media","json").build(true);
URI uri= uriComponents.toUri();

或

UriComponents uriComponents = UriComponentsBuilder.fromHttpUrl(path + "?media=json").build(true);

也应该没问题。然后使用它，做

ResponseEntity<String> response = restTemplate.exchange(uri, HttpMethod.GET, request, String.class);

而不是

ResponseEntity<String> response = restTemplate.exchange(uri.toString()+ "?media=json", HttpMethod.GET, request, String.class);

如何为RestTemplate执行方法交换以便不更改uri
