json.Unmarshal did not work

[kingangelAOA]

Please answer these questions before submitting your issue. Thanks!

What version of Go are you using (go version)?

version : 1.9

Does this issue reproduce with the latest release?

What operating system and processor architecture are you using (go env)?

mac 10.12

What did you do?

         for index, url := range URLS {
	fmt.Println(index)
	iface.Hosts = []string{url}
	res, err := iface.Request()
	if err != nil {
		panic(err)
	}
	if res.StatusCode == 200 {
		body, err := ioutil.ReadAll(res.Body)
		if err != nil {
			panic(err)
		}
		var eleSoaResponse EleSoaResponse
		if err := json.Unmarshal(body, &eleSoaResponse); err != nil {
			panic(err)
		}
		var rankResponse RankResponse
		fmt.Println("begin json Unmarshal", len(eleSoaResponse.Result))
		if err := json.Unmarshal([]byte(eleSoaResponse.Result), &rankResponse); err != nil {
			fmt.Println("json Unmarshal err")
			panic(err)
		}
		fmt.Println("end json Unmarshal")
		if index == 0 {
			resMap["xg"] = rankResponse
		} else {
			resMap["wg"] = rankResponse
		}
	} else {
		body, err := ioutil.ReadAll(res.Body)
		if err != nil {
			panic(err)
		}
		panic(fmt.Errorf("request error, status: %d, body: %s", res.StatusCode, string(body)))
	}
      }

What did you expect to see?

0
begin json Unmarshal 97997
end json Unmarshal
1
begin json Unmarshal 97997
end json Unmarshal

What did you see instead?

0
begin json Unmarshal 97997
end json Unmarshal
1
begin json Unmarshal 97997

it is pending and json.Unmarshal did not catch error

eleSoaResponse.Result is too big

This is not a self-contained piece of code to reproduce the issue. Please provide one on play.golang.org.

I also don't understand what you think the issue is here - "did not catch error" and "Result is too big" are too vague.

                    var rankResponse RankResponse
                    var b bytes.Buffer
		fmt.Println("begin json Unmarshal", len(b.Bytes()))
		b.Write([]byte(eleSoaResponse.Result))
		fmt.Println(len(b.Bytes()))
		if err := json.Unmarshal(b.Bytes(), &rankResponse); err != nil {
			fmt.Println("json Unmarshal err")
			panic(err)
		}
		fmt.Println("end json Unmarshal")

result:
begin json Unmarshal 0
97977
end json Unmarshal
begin json Unmarshal 0
97977

when run second
"end json Unmarshal" did not print

it is pending at json.Unmarshal(b.Bytes(), &rankResponse)

run first can Unmarshal json

but secon can not

This is still not a self-contained program. Please provide one on https://play.golang.org/. Without one, it's very hard to understand what's going on or what you believe the issue to be.

Sorry, I found the problem, third-party package caused the task to lock up
