Passing Parameters with HttpURLConnection
提问by TheLettuceMaster
With the old Apache stuff deprecated in API 22, I am finally getting around to updating my network stuff.
随着 API 22 中旧的 Apache 内容被弃用，我终于开始更新我的网络内容。
Using openConnection()seems pretty straight forward. However, I have not seen any good example to send parameters with it.
使用openConnection()似乎很简单。但是，我还没有看到任何用它发送参数的好例子。
How would I update this code?
我将如何更新此代码？
ArrayList<NameValuePair> param = new ArrayList<NameValuePair>();
param.add(new BasicNameValuePair("user_id",String.valueOf(userId)));
httpPost.setEntity(new UrlEncodedFormEntity(param));
Now that NameValuePairand BasicNameValuePairare also deprecated.
现在，NameValuePair和BasicNameValuePair也已弃用。
EDIT: My server side phpcode doesn't expect JSON parameters and I can't all of the sudden switch due to existing users -- so a non-JSON answer is recommended.
编辑：我的服务器端php代码不需要 JSON 参数，而且由于现有用户，我不能突然切换 - 因此建议使用非 JSON 答案。
EDIT2: I just need to Target Android 4.1+ at the moment.
EDIT2：我现在只需要定位 Android 4.1+。

I fixed it like this:
我是这样修复的：
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
Here is parameter stuff:
这是参数的东西：
String charset = "UTF-8";
String s = "unit_type=" + URLEncoder.encode(MainActivity.distance_units, charset);
s += "&long=" + URLEncoder.encode(String.valueOf(MainActivity.mLongitude), charset);
s += "&lat=" + URLEncoder.encode(String.valueOf(MainActivity.mLatitude), charset);
s += "&user_id=" + URLEncoder.encode(String.valueOf(MyndQuest.userId), charset);
conn.setFixedLengthStreamingMode(s.getBytes().length);
PrintWriter out = new PrintWriter(conn.getOutputStream());
out.print(s);
out.close();
