Java 为什么在向服务器发送数据时将单词替换为问号

我尝试将数据发送到服务器，但当我发送波斯语单词时，它会发送问号，例如，如果我发送，它会发送

我怎样才能解决这个问题

这是我的FragmentForm.class：

有关URL中可接受的字符，请参见此。url中不支持波斯字符作为get参数。您可以使用http post将数据发送到服务器。

首先确保您从android端发送正确的单词波斯语，可能您的java代码没有发送UTF-8格式的文本，然后确保您的服务器、数据库和表集合是utf8\u波斯语\u ci

改变这个

BufferedReader in = new BufferedReader(
                        new InputStreamReader(urlConnection.getInputStream()));

为此：

BufferedReader in = new BufferedReader(
             new InputStreamReader(urlConnection.getInputStream(), "utf-8"),8);

---

您应该更改服务器接受的编码以及您的文本中包含的编码request@Pavlostnx兄弟，但如何以及在我的代码：D检查这个链接`我尝试将数据发送到服务器``。下次请立即告诉我，您试图在url的参数中添加波斯语字符。这就节省了那些想帮忙的人的时间，他们现在必须钻研很多代码。

BufferedReader in = new BufferedReader(
             new InputStreamReader(urlConnection.getInputStream(), "utf-8"),8);
