我目前正在开发一个具有大量服务器端通信的 Android 应用程序。昨天我收到一个错误报告,说用户无法发送(简单)特殊字符,例如 ëäï。
我搜索但没有发现任何有用的东西可能重复(没有答案): https ://stackoverflow.com/questions/12388974/android-httpurlconnection-post-special-charactes-to-rest-clint-in-android
我的相关代码:
public void execute(String method) {
HttpsURLConnection urlConnection = null;
try {
URL url = new URL(this.url);
urlConnection = (HttpsURLConnection) url.openConnection();
urlConnection.setRequestMethod(method);
urlConnection.setReadTimeout(30 * 1000);
urlConnection.setDoInput(true);
if (secure)
urlConnection.setRequestProperty("Authorization", "Basic " + getCredentials());
if (body != null) {
urlConnection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
urlConnection.setFixedLengthStreamingMode(body.length());
urlConnection.setDoOutput(true);
DataOutputStream dos = new DataOutputStream(urlConnection.getOutputStream());
dos.writeBytes(body);
dos.flush();
dos.close();
}
responseCode = urlConnection.getResponseCode();
message = urlConnection.getResponseMessage();
InputStream in = null;
try {
in = new BufferedInputStream(urlConnection.getInputStream(), 2048);
} catch (Exception e) {
in = new BufferedInputStream(urlConnection.getErrorStream(), 2048);
}
if (in != null)
response = convertStreamToString(in);
} catch (UnknownHostException no_con) {
responseCode = 101;
}catch (ConnectException no_con_2){
responseCode = 101;
}catch(IOException io_ex){
if(io_ex.getMessage().contains("No authentication challenges found")){
responseCode = 401;
}else
responseCode = 101;
} catch (Exception e) {
e.printStackTrace();
} finally {
if (urlConnection != null)
urlConnection.disconnect();
}
}
body
是一个字符串;-)
希望我们能一起解决这个问题
更新:
试过:
writeUTF()
需要能够理解修改后的 UTF-8 的服务器
byte[] buf = body.getBytes("UTF-8");
dos.write(buf, 0, buf.length);
字符串有效,但没有特殊字符
更新:让它与 StringEntity(* string, "UTF-8") 一起工作,然后将结果解析为 byte[] 并用 dos.write(byte[]) 写入它!
