由于 PHP-FPM 的特殊生命周期，导致 PHP 的 gRPC 官方代码生成器只能生成数据结构和客户端代码，无法像 golang/node.js/python 一样能同时生成服务器代码；传统方式如果要搭建 PHP gRPC 服务器只能借助 nginx+h2+phpfpm 来搭建，这样就不需要 server 代码了，但是短生命周期又无法很好的支持服务注册，因为这些原因导致 PHP 在 gRPC 中一直都是充当 Client 的角色，Mix gRPC 提供了基于 Swoole 的方案：. 让 PHP 编写 gRPC 和 Golang 一样方便快捷，同时性能强劲.

QUESTION
I'm trying to implement a stream in Rust for use in a tonic GRPC handler and encountered this difficulty: most ways of creating streams don't have easily-expressible types, yet the GRPC trait I need to implement requires a specific Stream type. Something like this (simplified):

Answered 2022-Mar-28 at 22:40Unfortunately there is no good way in stable Rust to do that without dynamic dispatch. You have to use dyn Stream, and futures provides BoxStream for that:
QUESTION
I have added android:exported="true" to my only activity in manifest but still getting below error after updating compile sdk and target sdk version to 31.I also tried rebuilding the project , invalidating cache and restart but that didn't helped
Error- Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined. See https://developer.android.com/guide/topics/manifest/activity-element#exported for details.
ANSWER
Answered 2021-Oct-05 at 10:38After the build has failed go to AndroidManifest.xml and in the bottom click merged manifest see which activities which have intent-filter but don't have exported=true attribute. Or you can just get the activities which are giving error.
Add these activities to your App manifest with android:exported="true" and app tools:node="merge" this will add exported attribute to the activities giving error.

QUESTION
I am trying to call a gRPC service from Angular application.
If I host the server locally and call it from Anuglar application then it works.
...ANSWER
Answered 2022-Feb-26 at 16:38This is most likely caused by the common CORS Browser restrictions, and not exactly by angular. This question contains great guidance on CORS.
Calling HTTP services from a Node app (or from postman) will not enforce CORS, while calling it from a market standard browser certainly would.
I know there is far more to it than my next simplified comments but this should give you a starting point (a deeper dive is in the links I shared above)
For browsers to execute XMLHttpRequest's from one website to other domains (or other ports of the same domain):
- the browser will send an OPTIONS HTTP request before every real request to the other domain and only allow the actual request when the OPTIONS response headers authorize it.
- the "other" website must be configure to reply to OPTIONS requests with specific Headers (
Access-Control-Allow-Origin,Access-Control-Request-*...).
==> If the other server does not reply to OPTIONS requests or does not provide the appropriate headers in the OPTIONS response, you can get a range of different errors, and "Response closed without headers" is one of them.
I believe your gRPC web application is not configured with the proper CORS to authorize communications from the website where you are hosting your angular application (even if it is localhost, you would still need to configure it).
This article has practical guidance on how to configure CORS on .netcore applications
and finally, This github issue / responses contains some more info about a similar error some people faced with gRPC, you might have stepped into the same one. If you have already configured your CORS rules.

QUESTION
I have an application running on my local machine that uses React -> gRPC-Web -> Envoy -> Go app and everything runs with no problems. I'm trying to deploy this using GKE Autopilot and I just haven't been able to get the configuration right. I'm new to all of GCP/GKE, so I'm looking for help to figure out where I'm going wrong.
I was following this doc initially, even though I only have one gRPC service: https://cloud.google.com/architecture/exposing-grpc-services-on-gke-using-envoy-proxy
From what I've read, GKE Autopilot mode requires using External HTTP(s) load balancing instead of Network Load Balancing as described in the above solution, so I've been trying to get that to work. After a variety of attempts, my current strategy has an Ingress, BackendConfig, Service, and Deployment. The deployment has three containers: my app, an Envoy sidecar to transform the gRPC-Web requests and responses, and a cloud SQL proxy sidecar. I eventually want to be using TLS, but for now, I left that out so it wouldn't complicate things even more.
When I apply all of the configs, the backend service shows one backend in one zone and the health check fails. The health check is set for port 8080 and path /healthz which is what I think I've specified in the deployment config, but I'm suspicious because when I look at the details for the envoy-sidecar container, it shows the Readiness probe as: http-get HTTP://:0/healthz headers=x-envoy-livenessprobe:healthz. Does ":0" just mean it's using the default address and port for the container, or does indicate a config problem?
I've been reading various docs and just haven't been able to piece it all together. Is there an example somewhere that shows how this can be done? I've been searching and haven't found one.
My current configs are:
...ANSWER
Answered 2021-Oct-14 at 22:35Here is some documentation about Setting up HTTP(S) Load Balancing with Ingress. This tutorial shows how to run a web application behind an external HTTP(S) load balancer by configuring the Ingress resource.
Related to Creating a HTTP Load Balancer on GKE using Ingress, I found two threads where instances created are marked as unhealthy.
In the first one, they mention the necessity to manually enable a firewall rule to allow http load balancer ip range to pass health check.
In the second one, they mention that the Pod’s spec must also include containerPort. Example:
QUESTION
I can't recall if I have ever tinkered with the settings of Android Emulator, but I've been testing my app on an Android Emulator using Android Studio, and every time I take a screenshot, it crashes.
I tried deleting, and wiping, and creating a new Emulator. None of it works. I tried also to take a screenshot without running my app, with a fresh emulator, and the same problem occurs. It just crashes whenever I try to take a picture.
Android Studio reports this error:
Blockquote WARNING | unexpected system image feature string, emulator might not function correctly, please try updating the emulator. WARNING | cannot add library /Users/sbenati/Library/Android/sdk/emulator/qemu/darwin-x86_64/lib64/vulkan/libvulkan.dylib: failed INFO | configAndStartRenderer: setting vsync to 60 hz INFO | added library /Users/sbenati/Library/Android/sdk/emulator/lib64/vulkan/libvulkan.dylib WARNING | cannot add library /Users/sbenati/Library/Android/sdk/emulator/qemu/darwin-x86_64/lib64/vulkan/libMoltenVK.dylib: failed INFO | added library /Users/sbenati/Library/Android/sdk/emulator/lib64/vulkan/libMoltenVK.dylib INFO | Started GRPC server at 127.0.0.1:8554, security: Local INFO | Advertising in: /Users/sbenati/Library/Caches/TemporaryItems/avd/running/pid_935.ini
My machine is a Mac with 32GB of RAM and i7 CPU, so I can't imaging this an issue with system performance.
If no one has any suggestions, I will have to just reinstall everything. Thanks for the tips everyone.
Edit:
I ran this on a new Mac mini I recently acquired, and got this really helpful message. I traced it down to a suggested solution about switching off Vulcan, but it did not work for me.
...ANSWER
Answered 2021-Dec-04 at 02:28I've been having the same problem (I'm on macOS Monterey), each time I try to take a screenshot the emulator crashes.
Sadly I haven't found a direct solution to this problem, that is a solution fixing the issue in the simulator. But I have learned that it is possible to take screenshots of the app from inside Android Studio, using Logcat.
Essentially, when you're running your app, if you go to the Logcat tab, there is a screenshot option which does seem to work without crashing. I've added a link to developer.android.com which explains how to do it.
Even thought this doesn't exactly fix the problem I hope it helps!
Take a screenshot (through android studio)
Edit:
I am happy to report that after a recent update for the emulator released by the developers, the issue no longer exists for me! The screenshot button has now started working again.
So if someone has the issue, I believe it can now be fixed by just updating your emulator to the latest version available.
