我正在尝试从 Android 设备向基于 Django 的后端发送 POST 请求。我正在使用这些方法尝试这种方法，
方法 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();
}

方法 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();
回应
org.apache.http.message.BasicHttpResponse@40525230
在进一步学习时，我收到上述请求的错误 403。
请指出我在这种方法中犯下的错误。也欢迎任何其他方法和代码 fragment 。
编辑 1
我得到的 HTTP 响应为 200。 HttpEntity entity = response.getEntity(); 的值代码是org.apache.http.conn.BasicMangedEntity@4055505d0
最佳答案
你没有说第一种方法有什么问题。
对于第二个，如果您收到 403，可能是因为跨站点请求伪造保护 (CSRF)。请参阅the docs该怎么办。
