我正在開發一個沙箱數據庫中的測試應用程序MongoLab
。 當執行一個REST查詢,我得到了正確的文件,但在我的Android應用程序拋出異常執行相同的:對MongoLab的Android HTTP GET請求
查詢: https://api.mongolab.com/api/1/databases/my-db/collections/my-col?q={id:"123"}&apiKey=***
(當然分貝,山口和API密鑰的定義)。 把這個URI放到瀏覽器中可以找回我正在查找的文檔。
機器人:
class RequestTask extends AsyncTask<String, String, String> {
@Override
protected String doInBackground(String... uri) {
Log.i("URI", uri[0]);
HttpClient httpclient = new DefaultHttpClient();
HttpResponse response;
String responseString = null;
try {
response = httpclient.execute(new HttpGet(uri[0]));
StatusLine statusLine = response.getStatusLine();
if (statusLine.getStatusCode() == HttpStatus.SC_OK) {
ByteArrayOutputStream out = new ByteArrayOutputStream();
response.getEntity().writeTo(out);
responseString = out.toString();
out.close();
} else {
// Closes the connection.
response.getEntity().getContent().close();
throw new IOException(statusLine.getReasonPhrase());
}
} catch (ClientProtocolException e) {
Log.e(LOG_TAG, e.getMessage());
} catch (IOException e) {
Log.e(LOG_TAG, e.getMessage());
}
return responseString;
}
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
Log.i(LOG_TAG, result);
}
}
例外:
java.lang.RuntimeException: An error occured while executing doInBackground()
...
Caused by: java.lang.IllegalArgumentException: Illegal character in query at index 71: https://api.mongolab.com/api/1/databases/my-db/collections/my-col?q={"id":"123"}&apiKey=***
在索引71的炭是my-col?q
後的第一=
,並且存在於該行的引用: response = httpclient.execute(new HttpGet(uri[0]));
爲什麼它在瀏覽器上運行良好,而不是在我的設備上運行? 雖然我已成功取出所有文件但沒有查詢,但...
感謝它的工作! – itaied
