我试图从我的android应用程序发布HttpRequest到基于python的后端abd遇到500请求代码错误。有时，它给出了403
App POST请求
private String Register(String email,String password) {
HttpClient httpclient = new DefaultHttpClient();
String responseStr="";
String URL=Constants.URL;
System.out.println(URL);
HttpPost httppost = new HttpPost(URL);
try {
// Add your data
InetAddress ipAddress=null;
try{
ipAddress=InetAddress.getLocalHost();
System.out.println("IP of my Android := "+ipAddress.getHostAddress());
}catch (Exception e){
System.out.println("Exception caught ="+e.getMessage());
}
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("email", email));
nameValuePairs.add(new BasicNameValuePair("password", password));
nameValuePairs.add(new BasicNameValuePair("ip", ipAddress.getHostAddress().toString()));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
System.out.println(email+","+password+","+ipAddress.getHostAddress().toString()+","+URL);
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
int responseCode = response.getStatusLine().getStatusCode();
System.out.println("after this"+responseCode);
switch(responseCode) {
case 200:
HttpEntity entity = response.getEntity();
if(entity != null) {
String responseBody = EntityUtils.toString(entity);
responseStr=responseBody;
}
break;
}
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(Registration.this,"error",
Toast.LENGTH_SHORT).show();
//Constants.AlertBox("Failed", "Unable to register. Please try again", Registration.this);
}
return responseStr;
}

答案 0 :(得分：-1)
您可以查看以下几项内容，
你无法在ui线程上调用http请求，将其移动到另一个线程或异步任务。
看起来你在本地机器上启动你的测试服务器，你需要确保它可以通过你的设备连接，你需要启动你的django服务器，python manage.py runserver 0.0.0.0:8000 < / p>
