我想從一個文件(a.txt)中搜索我的一些查詢,並在Yahoo!中搜索它們。答案網站,最後寫在另一個文件(b.txt)檢索結果閱讀Yahoo!時出錯。回答網站
我的代碼如下:
public static void run() throws IOException {
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("XX.XX.XX.XX", 8080));
LineNumberReader lnr = new LineNumberReader(new FileReader(new File("a.txt")));
lnr.skip(Long.MAX_VALUE);
int len = lnr.getLineNumber();
lnr.close();
for (int i = 0; i < len; i = i++) {
String ll = Files.readAllLines(Paths.get("a.txt")).get(i);
String l = URLEncoder.encode(ll, "UTF-8");
String surl = "https://answers.yahoo.com/search/search_result?p=" + l + "&sort=rel";
System.out.println("Search URL: " + surl);
URL url = new URL(surl);
InputStream in = url.openConnection(proxy).getInputStream();
BufferedReader rd = new BufferedReader(new InputStreamReader(in));
StringBuffer sb = new StringBuffer();
String line;
while ((line = rd.readLine()) != null) {
PrintWriter pw = new PrintWriter(new FileOutputStream(new File("b.txt"), true));
pw.println(line);
pw.close();
}
rd.close();
}
但是,我得到的錯誤如下:
Exception in thread "main" java.io.FileNotFoundException: https://answers.search.yahoo.com/search?p=How+a+13+year+old+boy+can+lose+weight%3F&sort=rel
at sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1834)
at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1439)
at sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(HttpsURLConnectionImpl.java:254)
at Yahoo.run(Yahoo.java:117)
at Main.main(Main.java:36)
但是,當我在瀏覽器網址中使用搜索字符串時,希望的結果顯示在Yahoo!現場。
它不適用於Yahoo!搜索?使用此代碼,我現在可以訪問其他網站。對於使用BOSS API,根據您的[示例](https://developer.yahoo.com/boss/search/boss_api_guide/codeexamples.html#oauth_java),有哪些必需的jar文件? –
