我遇到过一个问题 - 当您已登录并尝试访问另一个安全页面时,返回401错误消息。对我来说这个问题的神秘之处在于,如果通过Firefox RestCLient或iOS应用程序检查它,但无法通过Chrome Advanced Rest Client和Android应用程序访问,我可以在您登录后访问其他安全页面。但是,内容类型和其他必要的参数在Web工具和应用程序中设置相同。我曾尝试使用编码登录设置不同的auth标头:pass但它不需要t help and it doesn
因为它应该没有它,我认为(至少FF和iOS应用程序没有这个标头工作)。怎么会错?
Chrome的响应标头:
401 Unauthorized
Loading time:

这是我在Android应用程序中的Restful代码的和平:
public String serverRequest(int action, Bundle params) {
if (action == 0) {
if (Const.DEBUG_ENABLED)
Log.e(TAG, "You did not pass action.");
return "You did not pass action.";
}
try {
HttpRequestBase request = null;
HttpPost postRequest = null;
switch (action) {
case SIGN_IN:
request = new HttpPost();
request.setURI(new URI(SIGNIN_URL));
request.setHeader("Content-Type", "application/x-www-form-urlencoded; charset=utf-8");
postRequest = (HttpPost) request;
if (params != null) {
UrlEncodedFormEntity formEntity = new
UrlEncodedFormEntity(paramsToList(params));
postRequest.setEntity(formEntity);
}
break;
case SIGN_OUT:
request = new HttpPost();
request.setURI(new URI(SIGNOUT_URL));
request.setHeader("Content-Type", "application/x-www-form-urlencoded; charset=utf-8");
break;
case BANK_CARD_VERIFY:
request = new HttpPost();
request.setURI(new URI(BANK_CARD_VERIFY_URL));
request.setHeader("Content-Type", "application/x-www-form-urlencoded; charset=utf-8");
postRequest = (HttpPost) request;
if (params != null) {
UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(paramsToList(params));
postRequest.setEntity(formEntity);
}
break;
}
if (request != null) {
DefaultHttpClient client = new DefaultHttpClient();
if (Const.DEBUG_ENABLED)
Log.d(TAG, "Executing request: " + actionToString(action) + ": " + urlToString(action));
HttpResponse response = client.execute(request);
StatusLine responseStatus = response.getStatusLine();
int statusCode = responseStatus != null ? responseStatus.getStatusCode() : 0;
Log.d(TAG, "Status code: " + statusCode);
}
}
(登录和退出是公开的,bank_verify是受保护的页面.Android应用程序具有与Chrome相同的响应标头)。会话或别的东西似乎有问题,但我不确定。
修改 我好像发现了这里的问题。在Android应用程序中,我创建了一个新的HttpCLient对象,因为它丢失了所有旧数据。但另一个问题 - 如何使这个HttpCLient可重用?
答案 0 :(得分:0)
发现问题。我每次都重复使用httpClient,每次只使用一个包含所有会话数据的httpClient。只需实现if语句来检查我是否已经有httpclient对象然后你创建一个新的。
