Android デバイスから Django ベースのバックエンドに POST リクエストを送信しようとしています。私はこれらの方法を使用してこの方法を試していますが、
アプローチ 1
private String GetPickUpDetails(String pick_up_id2) {
StringBuilder response = new StringBuilder();
String stringUrl=Constants.PICKUP_DETAILS+pick_up_id2+"/";
URL url;
try {
url = new URL(stringUrl);
HttpURLConnection httpconn = (HttpURLConnection)url.openConnection();
if (httpconn.getResponseCode() == HttpURLConnection.HTTP_OK)
{
BufferedReader input = new BufferedReader(new InputStreamReader(httpconn.getInputStream()),8192);
String strLine = null;
while ((strLine = input.readLine()) != null)
{
response.append(strLine);
}
input.close();
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("This si the response march API "+response.toString()+" for url"+stringUrl);
return response.toString();
}

アプローチ 2
try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("scanned", jsonScanned.toString()));
nameValuePairs.add(new BasicNameValuePair("unscanned",jsonUnscanned.toString()));
nameValuePairs.add(new BasicNameValuePair("pickupid", pick_up_id));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
response = httpclient.execute(httppost);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
}
if (response.getStatusLine().getStatusCode() == 200)
{
HttpEntity entity = response.getEntity();
try {
json = EntityUtils.toString(entity);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
System.out.println("this is response"+json);
int iTmp=response.getStatusLine().getStatusCode();
return response.toString();
応答
org.apache.http.message.BasicHttpResponse@40525230
さらに勉強すると、上記のリクエストに対してエラー 403 が発生します。
このアプローチで私が犯している間違いを指摘してください。スニペットと一緒の他のアプローチも大歓迎です。

HTTP 応答を 200 として取得していますHttpEntity entity = response.getEntity();。コードの値はorg.apache.http.conn.BasicMangedEntity@4055505d0
