本文介绍了一个使用HttpUtils发送验证码及处理响应的例子，并演示了如何下载文件到指定路径。通过示例代码展示了参数设置、请求回调及错误处理的方法。

String code_url = "https://ic.snssdk.com/user/mobile/send_code/v2/";

HttpUtils httpUtils = new HttpUtils();
//网址
RequestParams params = new RequestParams();
params.addBodyParameter("type", "1");// 必填
params.addBodyParameter("mobile",shoujihao );// 必填

httpUtils.send(HttpMethod.POST, code_url, params,
new RequestCallBack<String>() {

@Override
public void onStart() {
// TODO Auto-generated method stub
super.onStart();
Log.i("TAG", "请求开始");
}

@Override
public void onFailure(HttpException arg0, String arg1) {

Log.i("TAG", "发送验证码请求失败: " + arg1);
Toast.makeText(PhoneZhuCe.this, "发送验证码请求失败: "+ arg1, 0).show();
}

@Override
public void onSuccess(ResponseInfo<String> arg0) {
Log.i("TAG", "发送验证码请求成功: " + arg0.result);

String s=arg0.result;

Gson gson=new Gson();
Loginphone fromJson = gson.fromJson(s, Loginphone.class);
String message = fromJson.getMessage();
if(message.equals("success")){
Intent intent = new Intent(PhoneZhuCe.this,
PhoneZhuCe2.class);

startActivity(intent);
}else{
Toast.makeText(PhoneZhuCe.this, fromJson.getData().getDescription(), 0)
.show();
}

}
});

下载数据：

String path = Environment.getExternalStorageDirectory().getPath();
String target=path+"/image/"+num+".png";//下载文件保存的路径

HttpUtils http=new HttpUtils();
//url路径
HttpHandler handler=http.download(url, target, true, true,new RequestCallBack<File>() {

@Override
public void onSuccess(ResponseInfo<File> arg0) {
// TODO Auto-generated method stub

}

@Override
public void onFailure(HttpException arg0, String arg1) {
// TODO Auto-generated method stub

}
});
