安卓Response 获取body的正确方式

    public static String getResponseBody(Response response) {

        Charset UTF8 = Charset.forName("UTF-8");
        ResponseBody responseBody = response.body();
        BufferedSource source = responseBody.source();
        try {
            source.request(Long.MAX_VALUE); // Buffer the entire body.
        } catch (IOException e) {
            e.printStackTrace();
        }
        Buffer buffer = source.buffer();

        Charset charset = UTF8;
        MediaType contentType = responseBody.contentType();
        if (contentType != null) {
            try {
                charset = contentType.charset(UTF8);
            } catch (UnsupportedCharsetException e) {
                e.printStackTrace();
            }
        }
        return buffer.clone().readString(charset);
    }

body.string()会截断流
