部署过程中发生了"go:find"错误 3

在部署 Go 云函数时，用户遇到了一个“go:find”错误，表明函数构建失败。调查后发现，该问题是由 Google Cloud Functions 包装器中的错误字符限制和对 Go 模块下载施加的人为超时造成的。通过供应依赖项，即在项目根目录中创建 vendor 目录并使用 go mod vendor 命令将依赖项复制到该目录，可以解决此问题。

我正在尝试部署go云函数。我已成功将此功能部署到一个 gcp 项目，但现在尝试将其部署到另一个项目时，我似乎无法部署它。

我使用此命令来部署该功能：

gcloud functions deploy generator --entry-point generator --memory 512mb --region europe-west1 --runtime go111 --trigger-event google.storage.object.finalize --trigger-resource gs://[redacted].appspot.com --project [redacted]

我在部署时使用 go.mod：

module gitlab.com/[redacted]/[redacted]/[redacted]

require (
    cloud.google.com/go v0.35.1
    firebase.google.com/go v3.6.0+incompatible
    github.com/tdewolff/parse/v2 v2.3.5
    golang.org/x/net v0.0.0-20190125091013-d26f9f9a57f3
    golang.org/x/text v0.3.1-0.20180807135948-17ff2d5776d2
    google.golang.org/api v0.1.0
)

我收到此错误消息，该消息在有趣的部分被截断，因此我看不到实际问题是什么（我认为）。

如何部署该函数？

解决方案

联系 Google 后，我已经弄清楚问题所在。

该问题是由 Google Cloud Functions 包装器中 4096 个字符的错误字符限制以及 Google 对 go mod 下载施加的人为超时造成的。

可以通过供应依赖项来解决此问题，如下所述：https://cloud.google.com/functions/docs/writing/specifying-dependencies-go#using_a_vendor_directory
