重新加载页面后，Bottle REST API生成不同的结果

Question

I just built my first REST API service, but it behaved weirdly... When this REST API is called, it does some calculation and returns the results. However, in my setup, without restarting the REST server, only the first time submission's result is correct. Results keep declining since the second submission. Has anyone had this issue before?

host

all_dic = {"APPRAT":APPRAT, "APPNUM":APPNUM, "APSPAC":APSPAC, "KOC":KOC, "METHAF":METHAF, "WETTED":WETTED,
           "METHOD":METHOD, "AIRFLG":AIRFLG, "YLOCEN":YLOCEN, "GRNFLG":GRNFLG, "GRSIZE":GRSIZE,
           "ORCFLG":ORCFLG, "INCORP":INCORP, "SOL":SOL, "METHAP":METHAP, "HYDHAP":HYDHAP, "FOTHAP":FOTHAP}

data = json.dumps(all_dic)
url='http://localhost:7777/myroute/' 
http_headers = {'Content-Type' : 'application/json'}
response = urlfetch.fetch(url=url, payload=data, method=urlfetch.POST, headers=http_headers)   
self.data_a= json.loads(response.content)["ff"]

REST Server

from bottle import route, run, post, request
import json

@post('/myroute/') 
def myroute():
    APPRAT = request.json["APPRAT"]
    APPNUM = request.json["APPNUM"]
    APSPAC = request.json["APSPAC"]
    KOC = request.json["KOC"]
    METHAF = request.json["METHAF"]
    WETTED = request.json["WETTED"]
    METHOD = request.json["METHOD"]
    AIRFLG = request.json["AIRFLG"]
    YLOCEN = request.json["YLOCEN"]
    GRNFLG = request.json["GRNFLG"]
    GRSIZE = request.json["GRSIZE"]
    ORCFLG = request.json["ORCFLG"]
    INCORP = request.json["INCORP"]
    SOL = request.json["SOL"]
    METHAP = request.json["METHAP"]
    HYDHAP = request.json["HYDHAP"]
    FOTHAP = request.json["FOTHAP"]

    import geneec
    ff=geneec.geneec2(APPRAT,APPNUM,APSPAC,KOC,METHAF,WETTED,METHOD,AIRFLG,YLOCEN,GRNFLG,GRSIZE,ORCFLG,INCORP,SOL,METHAP,HYDHAP,FOTHAP)
    print all the inputs
    print ff
    return json.dumps({'ff':ff})

run(host='localhost', port=7777, debug=True)

Where geneec is a FORTRAN program copiled into a Python module (geneec.pyd) using f2py . I have tested this mudule in a pure Python environment locally and it works fine (results will not be changed after multiple submissions.) So can anyone give me some suggestions on this issue? Thanks!

Update

Below are the results print on the server end. What I have seen is the same set of inputs generated different outputs

Answer 1

I doubt this is related to the REST call itself, since you are getting the same inputs printed out. I would look into what geneec2 is doing itself. You could test the REST call out with all of the parameters set to default values (and not the request information) and then see if this fixes anything. If that doesn't produce consistent results then you will need to recompile geneec2 with a bunch of print statements and see if that gives you a better idea of what is going wrong.
