weibo api 在获取用户信息或者其他信息时报错为： WeiboException 并且无错误码

今天在开发微博授权登录是碰到的一个问题：

上网百度后搜到这样一条帖子：http://www.tuicool.com/articles/FZJfAz2

说的是机器的回环地址问题，原谅我的半路出家，基本没怎么看明白。后来还是按照错误提示最后找到了这里

public Response httpRequest(HttpMethod method, Boolean WithTokenHeader)
throws WeiboException {
InetAddress ipaddr;
int responseCode = -1;
try {

// ipaddr = InetAddress.getLocalHost();
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() + "\n");

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();
}

}

问题出在headers.add(new Header("API-RemoteIP",
ipaddr.getHostAddress()));这个位置，你可以按照上面的博客改动测试下，也可以直接把这的ip换成你服务器的ip地址测试下
