从 android 连接到 PrestaShop 网络服务时出现 401 错误

我试图在 PrestaShop 中调用网络服务，但我收到 401 未授权错误.即使我已经通过了用户名密钥.我也尝试了身份验证器，但出现错误 HttpRetryingError.

I am trying to call a webservice in PrestaShop but i get 401 not authorized error. Even though i have passed the username key. I tried the authenticator too but i get an error HttpRetryingError.

在下面找到我所做的代码片段.

Find below the code snippet of what i have done.

方法一:

final String username = "key_here";
final String password = "";// leave it empty

URL urlToRequest = new URL(urlStr);
urlConnection = (HttpURLConnection) urlToRequest.openConnection();
urlConnection.setDoOutput(true);
urlConnection.setRequestMethod("GET");
urlConnection.setRequestProperty("Content-Type",
"text/xml;charset=utf-8");

String authToBytes = username + ":" + password;
//....
byte[] authBytes = org.apache.commons.codec.binary.Base64.encodeBase64(authToBytes.getBytes());
String authBytesString = new String(authBytes);
//then your code
urlConnection.setRequestProperty("Authorization","Basic " + authBytesString);

int statusCode = urlConnection.getResponseCode(); ---> i get 401
if (statusCode != HttpURLConnection.HTTP_OK) {
// throw some exception
InputStream in =
new BufferedInputStream(urlConnection.getInputStream());
Log.e("tag", getResponseText(in));
}

方法二

final String username = "keyvaluehere";
final String password = "";// leave it empty
String authToBytes = username + ":" + password;
byte[] authBytes = org.apache.commons.codec.binary.Base64.encodeBase64(authToBytes.getBytes());
String authBytesString = new String(authBytes);
HttpParams httpParameters = new BasicHttpParams();
// Set the timeout in milliseconds until a connection is established.
// The default value is zero, that means the timeout is not used.
int timeoutConnection = 30000;
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
// Set the default socket timeout (SO_TIMEOUT)
// in milliseconds which is the timeout for waiting for data.
int timeoutSocket = 30000;
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
HttpClient httpclient = new DefaultHttpClient(httpParameters);

HttpGet httpGet = new HttpGet(url);
httpGet.setHeader("Authorization","Basic " +authBytesString);
try {
HttpResponse response = httpclient.execute(httpGet);
String strResponse = EntityUtils.toString(response.getEntity());
if(response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
return strResponse;
}
return strResponse;
}catch(ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}

我什至尝试将字符串作为 ws_key 和键值传递，我什至将 url 称为 http://keyvalue@domain.com/api/namehere

I even tried passing the string as ws_key and the keyvalue and i even called the url as http://keyvalue@domain.com/api/namehere

但它也不起作用.请协助.

but it doesn't work too. Please assist.
