我做了一项研究:

  1. http://developer.yahoo.com/blogs/ydn/important-api-updates-changes-8060.html

  2. http://developer.yahoo.com/boss/search/

  3. http://tech.groups.yahoo.com/group/ysearchboss/msearch?query=http+request&submit=Search&charset=windows-1252

  4. http://developer.yahoo.com/java/howto-reqRestJava.html

我发现在 2008 年,Yahoo 对 java 编程的 http 方法进行了一项更改,这曾经是为“伞”这个词所做的:

"字符串请求 = " http://api.search.yahoo.com/WebSearchService/V1/webSearch?appid=YahooDemo&query=umbrella&results=10 ";"

关于:

HttpClient client = new HttpClient();

        GetMethod method = new GetMethod(request);


        // Send GET request

        int statusCode = client.executeMethod(method);

等等..现在他们有 BOSS 搜索 API 但直到现在我什么都没发现:

“如何在 Yahoo 搜索引擎中从 Java 发出 HTTP 请求?”

ps:请记住,雅虎会进行某种加密搜索,而 urlencoder.encode(query) 之类的东西将不起作用。

有人对我有意见吗?提前致谢!=]

编辑一:在 yahoo developer 找到这个“ http://developer.yahoo.com/boss/search/boss_api_guide/codeexamples.html#oauth_java ”,我正在尝试回答我自己的问题。

编辑一:

try {


    WebSearch ws = new WebSearch();

    ws.search(userQuery);

    List<WebSearchResult> results = ws.getResults();

    for(WebSearchResult result : results){
         System.out.println(result.getTitle());
    }

    // Setup connection properties (this doesn't open the connection)
    URLConnection connection = url.openConnection();
    connection.setRequestProperty("User-Agent", "Mozilla/5.0 (X11; U; Linux x86_64; en-GB; rv:1.8.1.6) Gecko/20070723 Iceweasel/2.0.0.6 (Debian-2.0.0.6-0etch1)");

    //Setup a reader
    BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));

    //Read line by line
    String line = null;
    while ((line = reader.readLine()) != null) {
    System.out.println (line);
    }
    //Close connection
    reader.close();
}

编辑二

 public int sendGetRequest(String url) throws IOException{
        //int ret = 500;
        try {
            URL u = new URL(url);
            HttpURLConnection uc = (HttpURLConnection) u.openConnection();
            uc.setRequestProperty("User-Agent", "Mozilla/5.0 (X11; U; Linux x86_64; en-GB; rv:1.8.1.6) Gecko/20070723 Iceweasel/2.0.0.6 (Debian-2.0.0.6-0etch1)");
            // ret = uc.getResponseCode();
           // if(200==ret){
                BufferedReader rd = new BufferedReader(new InputStreamReader(uc.getInputStream()));
                StringBuffer sb = new StringBuffer();
                String line;
                while ((line = rd.readLine()) != null) {
                    sb.append(line);
              //  }
                rd.close();
                setResponseBody(sb.toString());
            }
        }catch (MalformedURLException ex) {
            throw new IOException(url+" is not valid");
        }catch (IOException ie) {
            throw new IOException("IO Exception" + ie.getMessage());
        }
        return ret=0;
    }

查看来自 javaboss API 的这段代码——我对其进行了更改以设置阅读器——来自 uc.getResponseCode() 的值;为零。它在“主要”类名bosssearch中。这意味着 if 始终不同于 200 并且返回值始终为零...我认为这可能会使代码崩溃,但现在我需要将 java 文件导出为 jar 来替换它,因为它来自项目之外我遇到了一些问题,你怎么看?

您可以使用javaboss对 Yahoo! 执行搜索。搜索引擎:

WebSearch ws = new WebSearch();

ws.search("your_search_keywords_here");

System.out.println("Total hits : " + ws.getTotalResults());

//get a list of results
List<WebSearchResult> results = ws.getResults();

//iterate over the list and print every result title
for(WebSearchResult result : results){
     System.out.println(result.getTitle());
}

但是,您应该将用户代理设置为发出此类请求而不会出现 403 错误,正如我在回答您之前的一个问题(Google search from java request)中所解释的那样
