使用HttpUrlConnection将请求发布到服务器 [英] Post request to server using HttpUrlConnection
问题描述
我被困在两者之间.我想使用HttpUrlConnection实现POST方法,以发布用于将用户注册到服务器的电子邮件,名称和密码. 这是我的代码:
I am stuck in between. I want to implement a POST method using HttpUrlConnection to Post the email,name and password for registering a user to the server. Here is my code :
public void createNewProfile(View view){
new Post().execute("http://myurl.com");
}
private class Post extends AsyncTask<String, Void, String>{
@Override
protected String doInBackground(String... params) {
try {
URL url = new URL("http://myurl.com");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);
ContentValues values = new ContentValues();
values.put("email", "abc@xyz.com");
values.put("password", 123);
values.put("name","ABC");
OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os, "UTF-8"));
writer.write(getQuery(values));
writer.flush();
writer.close();
os.close();
response = conn.getResponseCode();
conn.connect();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
Log.i("Result",String.valueOf(e));
}
return null;
}
private String getQuery(ContentValues values) throws UnsupportedEncodingException
{
StringBuilder result = new StringBuilder();
boolean first = true;
for (Map.Entry<String, Object> entry : values.valueSet())
{
if (first)
first = false;
else
result.append("&");
result.append(URLEncoder.encode(entry.getKey(), "UTF-8"));
result.append("=");
result.append(URLEncoder.encode(String.valueOf(entry.getValue()), "UTF-8"));
}
Log.i("Result",result.toString() +" "+ String.valueOf(response));
return result.toString();
}
}
我不知道我在哪里犯错.我正在得到回应
I don't know where I am making mistake. I am getting following response
name=ABC&email=abc%40xyz.com&password=123 0
空格后的"0"是http响应代码返回的响应代码. 在浏览器中尝试输入URL时,URL是正确的. 我不知道我在哪里犯错;是我的服务器故障还是代码错误,因为我认为我的代码没有任何交互处理.
Where "0" after space is response code returned by http response code. While my URL is correct when I am trying it in the browser. I don't know where I am making mistake; Is it my server fault or there is mistake in my code because I don't think there is any interaction processing by my code.
我是Android Developement的初学者,曾尝试过很多次,使用了不同的代码,但出错了.

请帮助! 预先感谢.
推荐答案
尝试如下操作:
try {
url = new URL(params[0]);
httpURLConnection = (HttpURLConnection) url.openConnection();
httpURLConnection.setDoInput(true);
httpURLConnection.setDoOutput(true);
httpURLConnection.setRequestMethod("POST");
outputStream = httpURLConnection.getOutputStream();
bufferedWriter = new BufferedWriter(new OutputStreamWriter(outputStream));
bufferedWriter.write(myValues);
bufferedWriter.flush();
int statusCode = httpURLConnection.getResponseCode();
Log.d(Constants.LOG_TAG, " The status code is " + statusCode);
if (statusCode == 200) {
inputStream = new BufferedInputStream(httpURLConnection.getInputStream());
response = convertInputStreamToString(inputStream);
Log.d(Constants.LOG_TAG, "The response is " + response);
JSONObject jsonObject = new JSONObject(response);
return true;
} else {
return false;
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (inputStream != null) {
inputStream.close();
}
if (outputStream != null) {
outputStream.close();
}
} catch (Exception e) {
e.printStackTrace();
}
}
