判断webdav信息是否正确

 @GetMapping(value = "exist")
    @ApiOperation(value = "信息是否正确")
    @ApiResponses(value = {@ApiResponse(code = 200, message = "OK")})
    public boolean exist(@ApiParam(value = "Token字符串", required = true) @RequestHeader(value = "Authorization") String token) {

        try {
            CredentialsProvider credentialsPovider = new BasicCredentialsProvider();
            Credentials creds = new UsernamePasswordCredentials("roger", "1234567");
            credentialsPovider.setCredentials(AuthScope.ANY, creds);
            HttpClientBuilder clientbuilder = HttpClients.custom();
            clientbuilder = clientbuilder.setDefaultCredentialsProvider(credentialsPovider);
            CloseableHttpClient httpclient = clientbuilder.build();
            HttpHead head = new HttpHead("http://192.168.190.121:15108");
            CloseableHttpResponse response = httpclient.execute(head);
            StatusLine statusLine = response.getStatusLine();
            return  isGoodResponse(statusLine.getStatusCode());
        }catch (Exception e){
            e.printStackTrace();
        }

        return false;
    }
