示例1: startApplication
import org.springframework.http.HttpHeaders; //導入方法依賴的package包/類
@Override
public StartingInfo startApplication(String appName) {
CloudApplication app = getApplication(appName);
if (app.getState() != CloudApplication.AppState.STARTED) {
HashMap<String, Object> appRequest = new HashMap<String, Object>();
appRequest.put("state", CloudApplication.AppState.STARTED);
HttpEntity<Object> requestEntity = new HttpEntity<Object>(appRequest);
ResponseEntity<String> entity = getRestTemplate().exchange(getUrl("/v2/apps/{guid}?stage_async=true"), HttpMethod.PUT,
requestEntity, String.class, app.getMeta().getGuid());
HttpHeaders headers = entity.getHeaders();
// Return a starting info, even with a null staging log value, as a non-null starting info
// indicates that the response entity did have headers. The API contract is to return starting info
// if there are headers in the response, null otherwise.
if (headers != null && !headers.isEmpty()) {
String stagingFile = headers.getFirst("x-app-staging-log");
if (stagingFile != null) {
try {
stagingFile = URLDecoder.decode(stagingFile, "UTF-8");
} catch (UnsupportedEncodingException e) {
logger.error("unexpected inability to UTF-8 decode", e);
}
}
// Return the starting info even if decoding failed or staging file is null
return new StartingInfo(stagingFile);
}
}
