我正確地發送HTTPPost了嗎?我正在檢查我的網絡服務器的encodedAuthString,並驗證字符串是否正確。不知道爲什麼我無法驗證。在Java中發送HTTP頭問題
public JSONObject connect(String url) {
HttpClient httpclient = new DefaultHttpClient();
// Prepare a request object
HttpPost httppost = new HttpPost(url);
String authString = usernameEditText.getText().toString() + ":" + passwordEditText.getText().toString();
String encodedAuthString = Base64.encodeToString(authString.getBytes(),Base64.DEFAULT);
String finalAuthString = "Basic " + encodedAuthString;
// Execute the request
HttpResponse response;
try {
httppost.addHeader("Authorization", finalAuthString);
response = httpclient.execute(httppost);
// Examine the response status
Log.i("Praeda", response.getStatusLine().toString());
// Get hold of the response entity
HttpEntity entity = response.getEntity();
if (entity != null) {
// A Simple JSON Response Read
InputStream instream = entity.getContent();
String result = convertStreamToString(instream);
// A Simple JSONObject Creation
JSONObject json = new JSONObject(result);
// Closing the input stream will trigger connection release
instream.close();
return json;
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
@Override
protected JSONObject doInBackground(String... urls) {
return connect(urls[0]);
}
@Override
protected void onPostExecute(JSONObject json) {
String authorized = "200";
String unauthorized = "401";
String notfound = "404";
String status = new String();
try {
// Get the messages array
JSONObject response = json.getJSONObject("response");
status = response.getString("status");
if(status.equals(authorized))
Toast.makeText(getApplicationContext(), "Authorized",Toast.LENGTH_SHORT).show();
else if (status.equals(unauthorized))
Toast.makeText(getApplicationContext(), "Unauthorized",Toast.LENGTH_SHORT).show();
else if(status.equals(notfound))
Toast.makeText(getApplicationContext(), "Not found",Toast.LENGTH_SHORT).show();
} catch (JSONException e) {
System.out.println(e);
} catch (NullPointerException e) {
System.out.println(e);
}
}
}
UPDATE:
當我硬編碼的編碼字符串,一切都很好。
當我使用的Base64編碼器,我得到了相同的結果編碼字符串,但服務器返回一個401
即使我嘗試setHeader()它不起作用。 – 2010-11-23 01:24:23
