Removing packages installed with go get

juse delete the source and package

麻烦，要是有一个命令就好了，找一下

It's safe to just delete the source directory and compiled package file. Find the source directory under $GOPATH/src and the package file under $GOPATH/pkg/<architecture>, for example: $GOPATH/pkg/windows_amd64.


example
go get github.com/golang/mock/mockgen


go clean -i github.com/golang/mock/mockgen

The -i flag causes clean to remove the corresponding installed
archive or binary (what 'go install' would create).

The -n flag causes clean to print the remove commands it would execute,
but not run them.

The -r flag causes clean to be applied recursively to all the
dependencies of the packages named by the import paths.


The -x flag causes clean to print remove commands as it executes them.

不知道安装的packagePath的话，找一下$GOPATH/pkg/windows_amd64啥的

go gin validator omitempty

細かくて面倒

・Pointer推奨、nilとZeroValueを区別するため
・bindingはpointerに対しても有効
・omtiemptyが必須ね。。

type XXXRequest struct {

Adate *time.Time `json:"aDate,omitempty" time_format:"2006-01-02”` 

B *float64`json:"b,omitempty" binding:"omitempty,min=-90,max=90”` 

C *float64 `json:"c,omitempty" binding:"omitempty,min=-180,max=180”`

}

jmeter org.apache.commons.httpclient.NoHttpResponseException

規律的に半分が上記のエラーになった。

良くわからない、

Server側が一方的に拒否した？

HttpHeaderの設定で、KeepAliveをOffして、治った。

今回のテスト対象がnginx + djangoなので、keepaliveの設定が悪い疑惑！

また調べる。
