on a map? i want to see the entire route!

解决方案

I assume you want to show the route on a Google Map, which is mandatory ;)

You can do this without using the JavaScript API, just use the Static Maps API with the path parameter containing the encoded polyline you'll find in the overview_polyline field of the route of your choice.

Example using the first route (that is, response.routes[0].overview_polyline.points) from your sample request:

"overview_polyline" : {
    "points" : "en_eEsoctEa@IuAvHzD~@hGrA~D~@i@vCgAlGa@|BqFp[kBOyBAgADk@Hw@JqBb@cIjAcC`@{Cr@iKrC_Bh@kDhAeCx@}Bn@}IpCcFtAq@Hs@D_A?yAEoAQi@OcA]kAg@}OoKmMqIkCgBoBgA}D{Bm@]ERiAxGoA`IYtAs@hCwAzDsB`EoDhGkDrGkBbDmBbD_CrC{@`AcAn@c@Pm@JUDa@?u@Cq@Mo@Um@c@cC}BmGgGgc@yd@qSmTsNiOwDoDqCmBkCuAcA]oC_AyCw@}Bc@_BO{BOwE@aDNiBRyARyBd@_K|Cag@bPsVdImDhAkBf@qCf@_AJqADeABcBCuAIqC_@kIqAuLaBgNmBuImAqFs@kL_BsEq@qEk@eGo@aFUqEIoOSiLI_DAgQQuDIiEa@u\\iDwBOiGw@yB_@uCy@yPsEaIwBiL_D{Cu@sAUgDk@uCYgAIeBCoEAax@nAgC@qCGcBIeCWmKmAmOaBkH_AqCc@}Aa@{CaAaBs@}BiAwMyGoAk@kBcAqHqDcBs@kC}@_D_AwCu@_BUgC[eDSeFIs@A{BFs`AtA_HH}CAoCIwBMsH]sMm@iMm@wG]qDYiFm@eFw@iCg@{Cs@cFsAwI}BqJgC{C{@cKmCuLaDuXmHwT_GuCu@sBc@wGkAqB[kDa@gE]eDQeGO{CCmC@}CFmCHcG\\yLx@wN`AcEXkETyDHiH@_DGgEO_F]sFi@oNuAgP_BwWgCsO{AuCa@eCe@eBa@wBm@uCaA}EwBwBiAaCyAsAaAyDcDoN_NmWqVgA_AiDeCwD_CyAy@wD_BeEyAsBk@kDs@uB]_CYyCU{AIyFOyCGyTW{SYiEEsJQ}ECyA@mDLyFVoCVyBZyCd@aDv@kDdAkA^gAh@qDrAsLtFmInDoBt@oAd@eATcG`AmCLo@Ds@?oCEeAG{lB_VaM{AyGs@aHYuISeB?gHMiLYyJe@gO{AwCUwGs@yf@_FaFc@u@KqI{@{Iy@wEa@{De@gO{AqC]mHk@gEOoPUoOQ_S[kKOmBIkBWs@Q}@[}@e@eAy@{AkBoAgBqDmHi@eAs@_Ae@e@sAaAcAm@_Ac@}@U_AM_BK}BM]@eCEyBJaALs@LsA\\_Bv@{BlAiBhAyAx@{Ap@wCtAaFjC_CfAwBv@cB\\kDt@_LnBwJbBmEb@gJp@M@{BLcD`@cDX}E`@_CLuBCcEWmKk@{Dg@cCYaEgAqCoAoBwAcCgC}EmGg@m@gDkEuE{FiBwBoBsCkAwB}@wBo@gCa@sCMqAMoD@uIBkDFuQ@qDBy@"
},

Full request, requires URL-encoding the encoded polyline:
