build it and deploy behind nginx.
then client query /users/1234567/places, /users/1234567, and so on...
get the response is {blank data}, {normal user(1234567) data} or {normal user(1234567) data}, {normal user(1234567) data}.
same prefix of query, and same handler, looks like it is overload the response by subsequent HTTP request.
How can I do it?
May need me to give an example of a response:
correct response is :
{ "meta": { "code": 200, "text": "OK" }, "data": { "count": 21, "place-tag-maps": [{ "id": "95842310160384", "place-id": "95551731663150", "tag-id": "95551579750669", "ct": "2014-07-01T09:07:28Z" }, { "id": "95842310160385", "place-id": "95551731663150", "tag-id": "95551579750694", "ct": "2015-01-15T17:41:23Z" }, { "id": "96262389694470", "place-id": "95551731663150", "tag-id": "95910120456455", "ct": "2016-07-18T13:11:39Z" }, ...], "places": [{ "id": "95551731663150", "name": "Kam Fung Restaurant", "address": "G/F, 41 Spring Garden Ln", "coordinate": { "latitude": 22.275576, "longitude": 114.172582 }, "telephone": "+852 2572 0526", "city-id": "95530516807703", "city": "Hong Kong", "country": "Hong Kong", "type": "4sq", "ref-id": "4b1613f8f964a520cdb623e3", "ct": "2016-02-23T07:42:43.565489Z", "mt": "2017-02-22T09:35:48.302929Z", "rating": 7.5, "stats": { "foursquare": { "count": 111, "value": 7.5 }, "spottly": { "save-count": 12 } }, "permanent-close": false, "price": "" }, ...], "posts": [{ "collection-id": "95551746474003", "coordinate": { "latitude": 22.275576, "longitude": 114.172582 }, "ct": "2017-02-22T09:35:47Z", "facebook-tag-users": [], "id": "97501586849795", "medias": [], "message": "", "mt": "2017-02-22T09:35:47Z", "owner-id": "96527264645120", "place-id": "95551731663150", "share-to": [], "star": 5, "status": "Done", "tags": [] }, ...], "users": [{ "id": "95551581323446", "uid": "hk_epicurus", "uid-ignore-case": "hk_epicurus", "name": "Hk Epicurus", "head": "https://d278wa0j9nq2mp.cloudfront.net/uploader/54aa335ddf4e63450002919a.jpeg", "site": "www.hkepicurus.com", "location": "Hong Kong", "description": "Hong Kong Food \u0026 Travel Bear.

but mistake response is
{ "meta": { "code": 200, "text": "OK" } } and { "meta": { "code": 200, "text": "OK" }, "data": { "friends": [{ "id": "97331335725056", "from-id": "97273770803200", "to-id": "96527264645120", "ct": "2017-01-23T07:58:41Z" }], "user": { "ct": "2013-04-30T23:30:05Z", "description": "Founder and Chief Everything Officer of Spottly.

the first response is error. or it's same as the second response.
sequence request is correct response, parallel request is incorrect response.
problem resolved。
the basic reason is this case:
var x = &{...} //init value
fillX(..., x) //fill the fields of x pointer
//here the fields of x pointer is not same to inner of fillX func
so, change to
var x = &{...}
x = fullX(..., x)
the problem resolved.
but why go pointer is the behavior?
Finally, this problem resolved.
Because the http.Handle register path-pattern and handler pair, the handler is construct by register time only-once, not for any request of path-pattern.
if record info within handler, It will been change by after request.
