最近在做一个接口对接，用的是httpclient的post方式请求，一直是报超时，url直接在浏览器中访问时却可以访问，不懂为什么？？
于是我吧url改成百度，但是还是一直报超时，不清楚了，各位帮忙看下
代码如下
public class HttpClientUtils {
public static void main(String arg[]) throws Exception {
String url = "http://www.baidu.com/";
// getDoGetURL2(url,"utf-8");//测试ok
// getDoGetURL(url,"utf-8");//测试ok
getDoPostResponseDataByURL(url, null, "utf-8", true); // 测试ok
// WebUtils.doPost(url, null, 30000, 30000);
}
/**
* <p>
* 执行一个HTTP POST请求，返回请求响应的HTML
* </p>
*
* @param url
* 请求的URL地址
* @param params
* 请求的查询参数,可以为null
* @param charset
* 字符集
* @param pretty
* 是否美化
* @return 返回请求响应的HTML
*/
public static String getDoPostResponseDataByURL(String url,
Map<String, String> params, String charset, boolean pretty) {
StringBuffer response = new StringBuffer();
HttpClient client = new HttpClient();
HttpMethod method = new PostMethod(url);
// 设置Http Post数据
if (params != null) {
HttpMethodParams p = new HttpMethodParams();
for (Map.Entry<String, String> entry : params.entrySet()) {
p.setParameter(entry.getKey(), entry.getValue());
}
method.setParams(p);
}
try {
client.executeMethod(method);
if (method.getStatusCode() == HttpStatus.SC_OK) {
// 读取为 InputStream，在网页内容数据量大时候推荐使用
BufferedReader reader = new BufferedReader(
new InputStreamReader(method.getResponseBodyAsStream(),
charset));
String line;
while ((line = reader.readLine()) != null) {
if (pretty)
response.append(line).append(
System.getProperty("line.separator"));
else
response.append(line);
}
reader.close();
}
} catch (IOException e) {
System.out.println("执行HTTP Post请求" + url + "时，发生异常！");
e.printStackTrace();
} finally {
method.releaseConnection();
}
System.out.println("--------------------" + response.toString());
return response.toString();
}
}
