Java 从android发送post请求
我已经挣扎了好几个小时了。我一直在尝试从我的android应用程序发出post请求。我发现我不能只从主线程发出请求，所以我发现我可以把它放在一个可运行的线程中。我四处寻找答案，尝试了很多人们使用的方法，这些方法对别人有用，但对我来说都不管用。我有点理解的是这个（不适合我）： })有简单的方法吗？还了解了okhttp库，我将尝试实现它，但我对gradle和导入外国库并不擅长 这就是我得到的：Java 从android发送post请求,java,android,multithreading,android-studio,request,Java,Android,Multithreading,Android Studio,Request,我已经挣扎了好几个小时了。我一直在尝试从我的android应用程序发出post请求。我发现我不能只从主线程发出请求，所以我发现我可以把它放在一个可运行的线程中。我四处寻找答案，尝试了很多人们使用的方法，这些方法对别人有用，但对我来说都不管用。我有点理解的是这个（不适合我）： })有简单的方法吗？还了解了okhttp库，我将尝试实现它，但我对gradle和导入外国库并不擅长 这就是我得到的： 11-28 20:49:49.587 10450-10450/?

非常感谢您的帮助。不确定您的错误。
但对于你的问题： 有简单的方法吗？还发现了okhttp库
这篇漂亮的文章比较了所有可用的网络库的各个方面。永远不要考虑自己构建标题、正文和解析响应。此外，重试、取消正在进行的请求、缓存等都可以通过库轻松完成。并在每一个因素上进行改装。我们正在使用它，它是好的。它支持JSON、XML、Jackson、Moshi、Protobuf以及Wire数据格式。您所需要做的就是创建请求主体模型类和响应模型。看看。好的。首先，感谢大家的回答。：）这很有帮助。我刚刚将okhttp库导入到项目中，从现在起我将使用它。看起来很容易。再次感谢 愿代码与大家同在 真诚地， Matic检查此项了解排球库，它将使您的生活更轻松。：）
