我正在嘗試編寫一個代碼來抓取網站並使用httpclient。我正在嘗試導入適當的類來運行我的程序,但它說包不存在。我已經看過他們的API,試圖找出它,但仍然不能。我的代碼是:如何在Java博士中導入HTTPClient?
import java.io.IOException;
import org.apache.commons.httpclient.*;
import org.apache.commons.httpclient.methods.*;
import java.util.Scanner
public class Scraper3 {
public static String scrapeWebsite() throws IOException {
HttpClient client = new DefaultHttpClient();
HttpGet get = new HttpGet("http://ichart.finance.yahoo.com/table.csv?s=MSFT");
HttpResponse response = client.execute(get);
HttpEntity entity = response.getEntity();
if (entity != null) {
Scanner scanner = new Scanner(entity.getContent());
while (scanner.hasNextLine()) {
System.out.println(scanner.nextLine());
}
}
}
}
你下載JAR文件,並把它們放在classpath?這可能也是讓你熟悉Maven的好時機......它讓我的生活變得更加輕鬆...... – ppeterka
我會研究Maven。我沒有將JAR添加到類路徑中。我會怎麼做呢? – cmart
