Python客戶端未將Python客戶端的Elasticsearch結果解析為json對象

Question

我無法從從Python（2.7）客戶端獲得的Elasticsearch（2.1.1）響應中創建Javascript對象。

Python代碼：

es=Elasticsearch();
@app.route('/output')
def findSpots():
    lat = request.args.get('lati')
    lon = request.args.get('longi')
    res=es.search(index="park_reg", doc_type="parksgn",body={"from": 0, "size": 1, "query": {"filtered": {"filter":  {"geo_distance":  {"distance": "500km","location": {"lat":lat,"lon":lon}}}}}})

return render_template("output.html",lat=lat,lon=lon, res=json.dumps(res))

JavaScript代碼：

var res = "{{res}}";
console.log(typeof(res)); //Gives string
document.write(res);
document.write("</br>")
document.write("</br>")

//Tried this as JSON.parse(res) was giving an error
var resStr =JSON.stringify(res);
document.write(resStr);
document.write("</br>")
document.write("</br>")

var resJSON = JSON.parse(resStr);
document.write(resJSON);

響應：

我確認“ res”是有效的JSON，但仍然無法正常工作。 “ resJSON”也給出了字符串。

因此，這就是我在控制台上的響應：

"{"hits": {"hits": [{"_score": 1.0, "_type": "parksgn", "_id": "13452823", "_source": {"canParkDays": [""], "x": 965522.6237, "seqnum": 5, "ordernum": "P-087419", "signdesc": "2 HOUR PARKING 9AM-7PM EXCEPT SUNDAY", "canParkDuration": -1, "noParkDays": [""], "SG_MUTCD_C": "R7-182R", "signfc": "", "canParkTime": [""], "location": {"lat": "40.591472", "lon": "-74.06743"}, "arrow": "", "canPark": "true", "y": 154772.6633, "distfromcurb": 310, "borough": "S", "noParkTime": [""], "id": 13452823}, "_index": "park_reg"}], "total": 376893, "max_score": 1.0}, "_shards": {"successful": 5, "failed": 0, "total": 5}, "took": 18, "timed_out": false}"

只需用雙引號（“）替換＆＃34就可以了

var res = "{{res}}".split(""").join("\"")
var resJSON = JSON.parse(res)
console.log(typeof(resJSON))
