处理url乱码问题
在使用HttpURLConnection发送POST请求时,如果请求参数中包含中文,且在后端显示出现乱码,可能是由于编码问题导致的。一种可能的原因是POST的form没有进行转码,服务器端将字节转换成utf8编码时,如果读取的字节不是3的倍数或只读取了部分字节,就会导致乱码。解决这个问题的方法是将获取服务器返回的输入流转换成utf-8格式的编码。可以通过在HttpURLConnection实例中将获取到的输入流写入BufferedReader时,指定编码为utf-8,代码如下:
InputStream inputStream = connection.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream,"utf-8")); //转成utf-8格式
StringBuilder response = new StringBuilder();
String line;
while((line=reader.readLine())!=null){
response.append(line);
}
System.out.println(response.toString());
这样可以确保从服务器获取的数据以utf-8格式进行解码,避免乱码问题的发生。 [2][3<span class="em">1</span><span class="em">2</span><span class="em">3</span>
