Golang Struct Won't Marshal to JSON -

this question has answer here:

• my structures not marshalling json 2 answers

i'm trying marshal struct in go json won't marshal , can't understand why.

my struct definitions

type podscondensed struct {     pods    []podcondensed  `json:"pods"` }  func (p *podscondensed) addpod(pod podcondensed) {     p.pods = append(p.pods, pod) }  type podcondensed struct {     name    string      `json:"name"`     colors  []string    `json:"colors"` } 

creating , marshaling test struct

fake_pods := podscondensed{}  fake_pod := podcondensed {     name: "tier2",     colors: []string{"blue", "green"}, }  fake_pods.addpod(fake_pod) fmt.println(fake_pods.pods)  jpods, _ := json.marshal(fake_pods) fmt.println(string(jpods)) 

output

[{tier2 [blue green]}] {} 

i'm not sure issue here, export json data structs, data being stored correctly , available print. wont marshal odd because contained in struct can marshaled json on own.

this common mistake: did not export values in podscondensed , podcondensed structures, json package not able use it. use capital letter in variable name so:

type podscondensed struct {     pods    []podcondensed  `json:"pods"` }  type podcondensed struct {     name    string      `json:"name"`     colors  []string    `json:"colors"` }
