我正在使用來自Microsoft Cognitive Services的示例代碼。它使用StringEntity類向REST API發出請求。 java編譯器似乎無法找到'symbol'StringEntity?這可能是什麼原因以及如何解決這個問題? 這裏去的代碼 -即使導入org.apache.http包後,爲什麼java不能找到StringEntity類?
import java.net.URI;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.utils.URIBuilder;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import org.apache.http.*;
public class NEWS_FETCHER
{
public static void main(String[] args)
{
HttpClient httpclient = HttpClients.createDefault();
try
{
URIBuilder builder = new URIBuilder("https://api.cognitive.microsoft.com/bing/v5.0/news/search");
builder.setParameter("q", "microsoft");
builder.setParameter("count", "10");
builder.setParameter("offset", "0");
builder.setParameter("mkt", "en-us");
builder.setParameter("safeSearch", "Moderate");
URI uri = builder.build();
HttpGet request = new HttpGet(uri);
request.setHeader("Ocp-Apim-Subscription-Key", "<Key goes here>");
// Request body
StringEntity reqEntity = new StringEntity("");
request.setEntity(reqEntity);
HttpResponse response = httpclient.execute(request);
HttpEntity entity = response.getEntity();
if (entity != null)
{
System.out.println(EntityUtils.toString(entity));
}
}
catch (Exception e)
{
System.out.println(e.getMessage());
}
}
}
大部分是從微軟API測試樣品取出。 https://dev.cognitive.microsoft.com/docs/services/56b43f72cf5ff8098cef380a/operations/56b449fbcf5ff81038d15cdf
你導入的jar?你在使用maven嗎?還是你手動導入罐子? –
如果你正在使用maven或gradle,請更新project.seems,如jar在構建路徑中不正確。 –
@Rajith Pemabandu,休息非所需的類顯示任何錯誤,只有StringEntity顯示,所以我想問題不是與進口。我想知道在什麼包字符串實體放置?我導入了整個導入org.apache.http。*;程序包,但它仍然無法工作。 –
