Android HttpURLConnection-返回用户请求后的响应
我有一个功能,注册一个表单到web服务器! 我这样称呼它:Android HttpURLConnection-返回用户请求后的响应,android,httpurlconnection,Android,Httpurlconnection,我有一个功能,注册一个表单到web服务器! 我这样称呼它: dialog = ProgressDialog.show(mActivity, "", getString(R.string.loading), true); new Thread(new Runnable() { public void run() { res = register(mobile, email, pass, name, family, gender); } }).start(
dialog = ProgressDialog.show(mActivity, "", getString(R.string.loading), true);
new Thread(new Runnable() {
public void run() {
res = register(mobile, email, pass, name, family, gender);
}
}).start();
问题在于,当用户第一次单击“注册”按钮时,它会显示“错误”,并且没有响应代码,但在第二次单击它的确定这是我的代码:
private String register(String mobile, String email, String pass, String name, String family, int gender) {
StringBuffer response = new StringBuffer();
URL url;
HttpURLConnection connection = null;
String urlParameters = null;
try {
urlParameters = USER_FIRST_NAME+"=" + URLEncoder.encode(name, "UTF-8") +
USER_LAST_NAME + "&=" + URLEncoder.encode(family, "UTF-8") +
USER_EMAIL + "&=" + URLEncoder.encode(email, "UTF-8") +
USER_MOBILE + "&=" + URLEncoder.encode(mobile, "UTF-8") +
USER_PASSWORD + "&=" + URLEncoder.encode(pass, "UTF-8") +
USER_GENDER + "&=" + URLEncoder.encode(String.valueOf(gender), "UTF-8");
//Create connection
url = new URL(registerLink);
connection = (HttpURLConnection)url.openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");
connection.setRequestProperty("Content-Length", "" +
Integer.toString(urlParameters.getBytes().length));
connection.setRequestProperty("Content-Language", "en-US");
connection.setUseCaches (false);
connection.setDoInput(true);
connection.setDoOutput(true);
//Send request
DataOutputStream wr = new DataOutputStream (
connection.getOutputStream ());
wr.writeBytes (urlParameters);
wr.flush ();
wr.close ();
//Get Response
int responceCode = connection.getResponseCode();
if (responceCode == HttpURLConnection.HTTP_OK) {
InputStream is = connection.getInputStream();
BufferedReader rd = new BufferedReader(new InputStreamReader(is));
String line;
while((line = rd.readLine()) != null) {
response.append(line);
response.append('\r');
}
rd.close();
}
else response.append( "Error "+String.valueOf(responceCode));
} catch (Exception e) {
e.printStackTrace();
} finally {
dialog.dismiss();
if(connection != null) {
connection.disconnect();
}
return response.toString();
}
}
注册按钮?我没有看到任何人。
USER\u LAST\u NAME+”&=“
?”??应该是“&”+USER\u LAST\u NAME+“=”
@greenapps为什么需要这个按钮?我问题中的第一部分代码是在BTN的onClick listner中,您应该在之前告诉我。这个问题救了我。您在哪里取消/取消进度对话框?请对“&=”评论作出反应。
