如何修复 HttpException:在收到完整标头之前连接已关闭 [英] How to fix HttpException: Connection closed before full header was received

问题描述

我最近在我的应用中升级了我的 Flutter 版本.但是当我想调试应用程序时，它显示了以下错误.

I have recently upgraded my flutter version in my app. But when I want to debug the application, it shows me the following error.

连接到服务协议时出错:HttpException: Connection closed before full header was received, URI = http://127.0.0.1:50795/ws

Error connecting to the service protocol: HttpException: Connection closed before full header was received, URI = http://127.0.0.1:50795/ws

有没有人在升级 flutter 版本后遇到同样的问题?如果有任何解决方法，请分享.

Is there anyone facing the same issue after upgrading the flutter version? If is there any workaround, please share.

我有一个临时解决办法，现在可以使用.当我将模拟器作为 Pixel 3 Android 9.+ Target (Q API) 运行时，会引发上述异常.我制作了第二个模拟设备，一个 Pixel 2 Android 9.0 目标(28 API)，这个目标运行良好.

I've got a temporary work around, which I can use for now. The exception above is thrown when I run the emulator as a Pixel 3 Android 9.+ Target (Q API). I made up a second emulated device, a Pixel 2 Android 9.0 Target (28 API), and this target works fine.

我还注意到 Pixel 2 目标在磁盘上占用 8.5GB，而 Pixel 3 目标仅占用 1.4GB.这让我怀疑 Pixel 3 目标是否遗漏了一些重要的东西.

I'm also noticing that the Pixel 2 target takes up 8.5GB on Disk, while the Pixel 3 target only takes up 1.4GB. It makes me wonder if the Pixel 3 target is missing some important things.
