多个HTTP POST按顺序进行 [英] Multiple HTTP POST in sequence

问题描述

我有一个应用程序欠发达，我需要按顺序执行3个HTTP POST。实现这个的最佳方法是什么？我应该

I have an app underdevelopment and I need to do 3 HTTP POSTs in sequence. What is the best way to implement this ? Should I

1. 让每个HTTP Post都有自己的Async Class和菊花链Async类（即从中调用第二个异步）第一个异步的onPostExecute）

1. Make each HTTP Post in it own Async Class and daisy chain the Async classes(i.e. call the second async from the onPostExecute of the first Async)

将所有HTTP POST放在单个异步的doInBcakGround中。

Put all the HTTP POSTs in the doInBcakGround of a single Async.

我知道如何进行HTTP POST请求，而我正在使用OKHTTP lib。我只是想知道按顺序进行多个POST的最佳练习。

I know how to do a HTTP POST request and I am using the OKHTTP lib. I just would like to know that the best practice it for multiple POSTs in sequence.

干杯

推荐答案

您的第一种方法会更好和非常模块化，因为您可以跟踪应用程序中的任何内容。在三种不同的<$ c中$ c> AsyncTask 你可以检查 postExceute（）哪个 AsyncTask 是完成其工作（更容易和更精确）AND

Your first approach will be better and quite modular as you can keep the track of anything in your application.In the three different AsyncTask you can have a check in postExceute() that which AsyncTask is done with its work (more easily and precisely) AND

>>>>>如果应用程序崩溃

然后 httpPost 中的哪一个失败。但是，第二个将使您的代码混乱，您将无法跟踪获取异常哪个 httpPost 请求失败（尽管如此）。

then which of the httpPost failed. However , the second one will make your code messy and you will be unable to track on getting Exception that which httpPost request failed(in a straight forward way though).

因此从第一个任务的onPostExecute启动第二个AsyncTask将是更好的方法。

另见：从另一个AsyncTask调用AsyncTask
