带有编码折线的Google Static Maps API [英] Google Static Maps API with encoded polyline

问题描述

我向google方向API发出了请求，并收到了以下JSON指示：

最后，我得到编码的折线数据：

  ecduHxqrE | RFS {SlW_w @ ZDC {@ IG @ cVlK}ž@Ĵ} AOG @ Z {AuGbdDibAfkGaBpcG}〜@ vrGy_AhhCoi @ FEB {bBxu @ kxAsSus @ | @ eAcLdyBci @ dcByi LY @`GrgC_S〜d @ e\\ wBugA_uBwuAusAoaCidAs〜Dq的{DiaAu`CuwAweAevBi @} dDwgCsrAwfBuqFkmBwzEu〜DenAa | Bi_BcuDmrAghF_ {B_hGa {@chAocAl [M_ @ pXwk @ {Z @} ZC〜A_hAmn @ mdAinBg_ @ ED {ö@ MOA {_ @ KZ @ SN @ CA @ oWmcCoQsUue @ `德{@yH {OA〜I @ meAliA} WAA] IJ @ QG @}ö@ W_ @ yVrT_k @ | Y {oCi` @ E_ @ RqEjOvUx\\`TjDv @义@ TTA〜的Gr} @`FXI @广告@ v] YJ | gAxlAjsAz_ @ | L @ oYzbBatAn_CdJdSv_B〜F @ rlAhk @`Ĵ@ F_ @`rAhpAfs @ F` @`kAfg @`Nr_AbgBtNt〜@ NB @ vRlc @ gXry @} WD ^ iIdv @zfCvgCj {GlcAzxEnkDfkGlgGtpE | EEF {AvzBx {BzvA | _B〜\\yAjyBxJzwA | WA〜_AznBlgAt_AbhBpsB`xChzAxsA | uAxVnxBnPb} AzCx`EnhA`qDwCnpG〜SvrCbmA | LCD {B〜jFdZzbCn {@ b`EhqA | aBb_Ad} BdkBxjEx [ VGC | HluEfUnkBtfB`eF〜mAzjD`V〜q因子@ Y_ @ pnEtv @ byChn @ TV @`dBjoFz_ @ KdbElc @ F] |？我@ BC @哒@ mKptA`Nhj @水性@ fHlAbK-M Z_UyOw ^ @纪苏@菊| @`qEX`cBnw @ | @ lAsRjlD_q〜nHgA`vH} M @ hvEs] gL的〜AzkCt [hiCcJlvFuAzzE`a @ jbDnlBxyG ||ç|〜B`d @ juCaiAf`DoQf`HhS | jBLpmBuLd`Dma @ zsBc [ ftGcx @ T | H {TnyGxTzdA_Bn [kPysBhZm`HvvAk`Rdb @ ehBoBypCdF} hB_YgcAzMqx @ nEohGriAi〜CA_ @ mpCopCkoBwpC_iIaKegKlIu {EuX_ {CGD {PBS ^ oXuu @ kpEqZmzDymBmwDt` @ qkEhEmzCjCiyBqSonCmKm | @rRweC {R} CBW {@ {fDeo @} U @q | @g} Cx_ @ quEqdBcyEs} Ba_HoQ {dJysDyvIiiBejDup @ E {d {mAuxDes @ a_BcoBkdGgEweJp |的Akt1 {@ U_ @ LG @_ {法新社@ suDzBmgAmLyp @ QW @ SX @ wdAafA_〜BukA`bAmeBfl @ orEtn @} F到@ xkAbVptAgk @ xv @ {} A | p @ cyAhjAsiHpEkyFbaAceHvLe〜Dli @ a〜Ary @ eeBx} @ lUbb @ jVzf @ _NhKs ^ yH {I 
  

现在理论上我应该可以在地图上显示这条路线，就像..

但是唉，这不起作用，任何人有什么想法为什么？这应该是一个相当基本的练习。因为它只是使用Google自己的API。

解决方案

似乎折线概述使用了很多\\所以我用\替换了所有\\的实例。

使用python替换字符串进行排序。

  string_new = string.replace（\\\\，\\）
  




I have made a request to google directions API and recived the following JSON directions:

At the bottom, I get the encoded polyline data:

Now In theory I should be able to display this route on a map, as easy as..

But alas, this does not work, anyone have any ideas as to why? It should be a fairly basic exercise. As it's just using googles own API.

解决方案

It seems the polyline overview used a lot of "\\" which causes the problem, so I replaced all instance of "\\" with "\".

Used python replace on the string to sort it.

string_new = string.replace("\\\\", "\\")
