往后台传输json字符串为例，其他类型同样做法
自定义Request继承Volley自带的StringRequest
GzipRequest.java
public class GzipRequest extends StringRequest { private String mData = null; public GzipRequest(String url, Response.Listener<String> listener, @Nullable Response.ErrorListener errorListener) { super(url, listener, errorListener);
} public GzipRequest(String url,String data, Response.Listener<String> listener, @Nullable Response.ErrorListener errorListener) { super(Method.POST,url, listener, errorListener);
mData = data;
} @Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String,String> headers = new HashMap<String, String>();
headers.put("Charset", "UTF-8");
headers.put("Accept-Encoding", "gzip,deflate");//客户端允许接收GZIP
headers.put("Content-Encoding", "gzip");//客户端发送GZIP内容
headers.put("Content-Type", "application/json");//根据后台要求，觉得Content-Type类型
return headers;
} @Override
public RetryPolicy getRetryPolicy() { return new DefaultRetryPolicy(); //setRetryPolicy(RetryPolicy policy);可自定义超时时间，重试次数等参数
} @Override
public byte[] getBody() throws AuthFailureError { return mData == null ? super.getBody() : compress(mData);
} @Override
protected Response<String> parseNetworkResponse(NetworkResponse response) {
String result = uncompress(response.data); return Response.success(result, HttpHeaderParser.parseCacheHeaders(response)); //return super.parseNetworkResponse(response);
} @Override
protected void deliverResponse(String response) {
} private byte[] compress(String str) { try (ByteArrayOutputStream outStream = new ByteArrayOutputStream()) { try (GZIPOutputStream gzip = new GZIPOutputStream(outStream)) {
gzip.write(str.getBytes(StandardCharsets.UTF_8));
} return out.toByteArray();
}catch (Exception E){ return new byte[0];
}
} private String uncompress(byte[] str){
ByteArrayOutputStream baos = new ByteArrayOutputStream(); try (GZIPInputStream gis = new GZIPInputStream(new ByteArrayInputStream(str))) { int b; while ((b = gis.read()) != -1) {
baos.write((byte) b);
}
}catch (Exception e){ return "";
} return new String(baos.toByteArray(), StandardCharsets.UTF_8);
}
}以上，有帮助到你的话随手点个赞^^
