## Purpose of errs package
|
||||
1. compatible with `error` interface
|
||||
2. encapsulate error message with functions in `easy_function.go`
|
||||
3. easy for gRPC client/server
|
||||
4. support err's chain by [Working with Errors in Go 1.13](https://blog.golang.org/go1.13-errors)
|
||||
|
||||
|
||||
## Example - Normal function
|
||||
Using builtin functions `InvalidInput` to generate `Err struct`
|
||||
|
||||
**please add your own functions if not exist**
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import "adc.github.trendmicro.com/commercial-mgcp/library-go/pkg/errs"
|
||||
|
||||
func handleParam(s string) error {
|
||||
// check user_id format
|
||||
if ok := userIDFormat(s); !ok {
|
||||
return errs.InvalidFormat("param user_id")
|
||||
}
|
||||
return nil
|
||||
}
|
||||
```
|
||||
|
||||
## Example - gRPC Server
|
||||
`GetAgent` is a method of gRPC server, it wraps `Err` struct to `status.Status` struct
|
||||
```go
|
||||
func (as *agentService) GetAgent(ctx context.Context, req *cloudep.GetAgentRequest) (*cloudep.GetAgentResponse, error) {
|
||||
l := log.WithFields(logger.Fields{"tenant_id": req.TenantId, "agent_id": req.AgentId, "method": "GetAgent"})
|
||||
|
||||
tenantID, err := primitive.ObjectIDFromHex(req.TenantId)
|
||||
if err != nil {
|
||||
// err maybe errs.Err or general error
|
||||
// it's safe to use Convert() here
|
||||
return nil, status.Convert(err).Err()
|
||||
}
|
||||
...
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
## Example - gRPC Client
|
||||
Calling `GetAgent` and retry when Category is "DB"
|
||||
```go
|
||||
client := cloudep.NewAgentServiceClient(conn)
|
||||
req := cloudep.GetAgentRequest{
|
||||
TenantId: "not-a-valid-object-id",
|
||||
AgentId: "5eb4fa99006d53c0cb6f9cfe",
|
||||
}
|
||||
|
||||
// Retry if DB error
|
||||
for retry := 3; retry > 0 ; retry-- {
|
||||
resp, err := client.GetAgent(context.Background(), &req)
|
||||
if err != nil {
|
||||
e := errs.FromGRPCError(err)
|
||||
if e.Category() == code.CatGRPC {
|
||||
if e.Code() == uint32(codes.Unavailable) {
|
||||
log.warn("GRPC service unavailable. Retrying...")
|
||||
continue
|
||||
}
|
||||
log.errorf("GRPC built-in error: %v", e)
|
||||
}
|
||||
if e.Category() == code.CatDB {
|
||||
log.warn("retry...")
|
||||
continue
|
||||
}
|
||||
}
|
||||
|
||||
break
|
||||
}
|
||||
```
|
||||
|
||||
## Example - REST server
|
||||
1. handling gRPC client error
|
||||
2. transfer to HTTP code
|
||||
3. transfer to Error body
|
||||
|
||||
```go
|
||||
func Handler(c *gin.Context) {
|
||||
|
||||
// handle error from gRPC client
|
||||
resp, err := client.GetAgent(context.Background(), &req)
|
||||
if err != nil {
|
||||
// to Err
|
||||
e := errs.FromGRPCError(err)
|
||||
|
||||
// get HTTP code & response struct
|
||||
// 2nd parameter true means return general error message to user
|
||||
c.JSON(e.HTTPStatus(), general.NewError(e, true))
|
||||
}
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
## Example - Error Chain
|
||||
1. set internal error by func `Wrap`
|
||||
2. check Err has any error in err's chain matches the target by `errors.Is`
|
||||
3. finds the first error in err's chain that matches target by `errors.As`
|
||||
|
||||
```go
|
||||
// define a specific err type
|
||||
type testErr struct {
|
||||
code int
|
||||
}
|
||||
|
||||
func (e *testErr) Error() string {
|
||||
return strconv.Itoa(e.code)
|
||||
}
|
||||
|
||||
func main() {
|
||||
layer1Err := &testErr{code: 123}
|
||||
// error chain: InvalidFormat -> layer 1 err
|
||||
layer2Err := InvalidFormat("field A", "")
|
||||
layer2Err.Wrap(layer1Err) //set internal error
|
||||
|
||||
// errors.Is should report true
|
||||
hasLayer1Err := errors.Is(layer2Err, layer1Err)
|
||||
|
||||
// errors.As should return internal error
|
||||
var internalErr *testErr
|
||||
ok := errors.As(layer2Err, &internalErr)
|
||||
}
|
||||
