撥打電話時這可能是重複的 - 但我找不到解決此問題的內容。來自Google路線API的格式錯誤的JSON從R
我正在使用httpGET()調用google方向API。
套餐:
require(RCurl)
require(rjson)
require(gooJSON)
代碼:
url = "http://maps.googleapis.com/maps/api/directions/json?origin=12.9673293,77.7173975&destination=12.9373613,77.700985&waypoints=optimize:true|12.9723379,77.7117611|12.9922162,77.715895|12.9629354,77.7122996&sensor=false"
routeJSON = httpGET(url= url)
routeList = fromJSON(routeJSON)
我得到:
Error in fromJSON(routeJSON) :
unexpected escaped character '\]' at pos 18
我寫的JSON到一個文件,並將其複製到jsoneditoronline.com。我:
Error: Parse error on line 51:
... "points" : "[email protected][\]\
-----------------------^
Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '[', got 'undefined'
validated by jsonlint
但是,當我把網址到瀏覽器並複製輸出到jsoneditoronline它的工作原理。
任何想法爲什麼它正在發生和/或如何規避它?
編輯:我試過gooJSON,但它似乎不支持地圖API V3。
