我做了一项研究:
我发现雅虎在 2008 年对 Java 编程的 http 方法进行了一项更改，即对单词“umbrella”进行的更改:
“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..现在他们有了 BOSS 搜索 API，但到目前为止我什么也没发现:
“如何在雅虎搜索引擎中从java发出HTTP请求？”
ps:记住雅虎进行了某种加密搜索，像 urlencoder.encode(query) 这样的东西将不起作用。
有人可以告诉我这件事吗？提前致谢! =]
编辑一:在雅虎开发者处找到了这个“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。
编辑一个:
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();
}
控制台报告错误:

编辑两个:
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。它位于“Main”类名称 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，因为它来自项目外部我我遇到了一些问题，你觉得怎么样？
最佳答案
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 as i explained in the answer to one of your previous questions (Google search from java request)
