Android语言解析难点

Question

在出现语言问题之前，它一直工作得很好。

但当用户名不是English时，服务器会发送错误。

这是我的代码。。。

HttpAsyncTaskCheckAuth checkAuth = new HttpAsyncTaskCheckAuth(SignUpActivity.this);
                checkAuth.execute("http://www.server_address.com//auth/login?email=" +
                        email +
                        "&name=" + name +
                        "&logged_in=" + "true");

如果我输入的名称是English，就可以正常工作。当用户输入的名称不是英文时，服务器不能成功执行。

我尝试了以下方法，但这些方法对我都不起作用

URLDecoder.decode(name, "UTF-8").replaceAll(" ","%20") 

和

URLEncoder.encode(name, "UTF-8").replaceAll(" ","%20")

Answer 1

您应该使用URLEncoder而不是URLDecoder。访问web源时，您的URL应该是编码的，而不是解码的。

所有其他字符都是不安全的，它们首先使用某种编码方案转换为一个或多个字节。建议使用的编码方案是UTF-8。但是，出于兼容性原因，如果未指定编码，则使用平台的默认编码。
