Parsing a json datetime in revel

阅读更多关于 Parsing a json datetime in revel

问题 I'm attempting to parse a Datetime in revel from a json request. The request looks something like this: { "startedAt": "2017-06-01 10:39", ... } The struct it's being decoded into looks like this: type MyStruct struct { StartedAt time.Time `json:"startedAt" bson:"startedAt"` ... } The decode line looks like this: json.NewDecoder(c.Request.Body).Decode(&MyStruct) Revel returns this error: interface conversion: error is *time.ParseError, not *errors.Error According to revel's documentation here

Go JSON decoding is very slow. What would be a better way to do it?

阅读更多关于 Go JSON decoding is very slow. What would be a better way to do it?

问题 I am using Go, Revel WAF and Redis. I have to store large json data in Redis (maybe 20MB). json.Unmarshal() takes about roughly 5 seconds. What would be a better way to do it? I tried JsonLib, encode/json, ffjson, megajson, but none of them were fast enough. I thought about using groupcache, but Json is updated in real time. This is the sample code: package main import ( "github.com/garyburd/redigo/redis" json "github.com/pquerna/ffjson/ffjson" ) func main() { c, err := redis.Dial("tcp", "

Iterate Go map get index

阅读更多关于 Iterate Go map get index

问题 In order to use revel 's even keyword in templates I would like to get the index of a map entry when iterating with range . Is there any way to do so? My map has the structure: map[string][]string 回答1: You can't do this only with template actions, but you may register a function which provides the necessary help. You may register a function which returns a function (closure), which alternates its return value whenever called (exactly how "odd" and "even" indices alternate): func isEven() func

问题 I'm using CentOS7; tried downloading the golang 1.5.1 binary and also yum install golang , and run into the same problem installed revel. Go works fine; when I do go version it displays the proper version. When I type go get -v github.com/revel/revel , a few packages download just fine.... until it gets to fsnotify.

阅读更多关于 Golang requirements.txt equivalent

问题 Coming from a python/django world, it'd be great to have something like a requirements.txt equivalent for go/revel. How can I do this? I know I can just write a requirements.txt file and then do something like cat reqiurements.txt | xargs go get But what if my requirements ALSO have requirements? The above command would attempt to "go get" them, and then they'd fail to build, since I don't have those requirements installed. Is there something I'm missing? 回答1: The command go get does exactly

问题 I'm using Revel for a small app and added SSL. When I update the config to point to http.port = 443, requests to port 80 are rejected instead of being forwarded. Is there a way to fix this on the Revel Framework? Thank you. # The port on which to listen. http.port = 443 # Whether to use SSL or not. http.ssl = true # Path to an X509 certificate file, if using SSL. http.sslcert = /root/go/src/saml/AlphaCerts/cert.crt # Path to an X509 certificate key, if using SSL. http.sslkey = /root/go/src
