我想通过RestTemplate发送请求。但我的网址有大括号(' {','}'),因此我有例外:"没有足够的变量值可用于展开...&#34 ;
我尝试通过uri
UriComponentsBuilder builder = UriComponentsBuilder.fromPath(url);
UriComponents uriComponents = builder.build();
URI uri = uriComponents.toUri();
但我得到了新的例外:" protocol = https host = null"。
如何使用我的网址发送请求?在URL中必须是大括号。
我的代码:
String url = "https://api.vk.com/method/execute?code=return[API.users.search({"count":1})];&access_token...
String result = restTemplate.getForObject(url, String.class);
答案 0 :(得分:1)
下面的代码使用UriComponentsBuilder
加密uri,使用RestTemplate
添加查询参数,如果有的话还设置HttpHeaders
。
public HttpEntity<String> getEntityByUri() {
String req = "https://api.vk.com/method/execute";
UriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl(req)
.queryParam("code",
"return[API.users.search({"count":1})]");
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.ALL));
HttpEntity<String> httpEntity = new HttpEntity<String>(headers);
return new RestTemplate().exchange(builder.build().encode().toUri(), HttpMethod.GET, httpEntity, String.class);
}
希望这会有所帮助并祝你好运!
