... 37 moreエラーメッセージを表示するメッセージは特に私のサーバーの名前localhostです.hao 231、新浪微博フォーラムでもこのような問題に直面している人が多いことがわかりました.
まず解決策についてお話しします.
1.再linuxを配備する場合は、まずマシンのホスト名を取得します:コマンド:hostnameを通じて、実は異常UnknownHostException:後であなたのマシン名が表示されます(私のはlocalhost.hao 231です).
2.次に、/etc/hostsで対応するloopback(ループバックアドレス)を構成し、以下のように追加します.
127.0.0.1 localhost
127.0.0.1 localhost.hao231
(もちろん、www.example.com(あなたのサイトのドメイン名)localhostを追加することもできます.hao231)
問題を解決する鍵は、Caused by:javaです.net.UnknownHostException
新浪weibo 4 j.http.HttpClient.JAvaのソースコードの抜粋は以下の通りです.
public Response httpRequest(HttpMethod method, Boolean WithTokenHeader)
throws WeiboException {
InetAddress ipaddr;
int responseCode = -1;
try {
ipaddr = InetAddress.getLocalHost();//UnknownHostException ， ip host name
List<Header> headers = new ArrayList<Header>();
if (WithTokenHeader) {
if (token == null) {
throw new IllegalStateException("Oauth2 token is not set!");
}
headers.add(new Header("Authorization", "OAuth2 " + token));
headers.add(new Header("API-RemoteIP", ipaddr.getHostAddress()));
client.getHostConfiguration().getParams()
.setParameter("http.default-headers", headers);
for (Header hd : headers) {
log(hd.getName() + ": " + hd.getValue());
}
}
method.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,
new DefaultHttpMethodRetryHandler(3, false));
client.executeMethod(method);
Header[] resHeader = method.getResponseHeaders();
responseCode = method.getStatusCode();
log("Response:");
log("https StatusCode:" + String.valueOf(responseCode));
for (Header header : resHeader) {
log(header.getName() + ":" + header.getValue());
}
Response response = new Response();
response.setResponseAsString(method.getResponseBodyAsString());
log(response.toString() + "
");
if (responseCode != OK)
{
try {
throw new WeiboException(getCause(responseCode),
response.asJSONObject(), method.getStatusCode());
} catch (JSONException e) {
e.printStackTrace();
}
}
return response;
} catch (IOException ioe) {
throw new WeiboException(ioe.getMessage(), ioe, responseCode);
} finally {
method.releaseConnection();
}
}getLocalHost()メソッドの紹介:
Returns the local host.
If there is a security manager, its
checkConnect method is called with the local host name and -1 as its arguments to see if the operation is allowed. If the operation is not allowed, an InetAddress representing the loopback address is returned. Returns:
the IP address of the local host.
Throws:
UnknownHostException - if no IP address for the
host could be found.See Also:
SecurityManager.checkConnect
