OSRM距离矩阵

Question

我希望OSRM能给我一个距离矩阵(就像ArcGIS的网络分析师一样)。

我注意到在documentation中，这是通过调用able API获得的。这适用于少量的位置(就像这个例子一样)，然而，当我提供一个包含1000个位置的列表时，它会减少我的HTTP请求，例如，即使是这个例子：

http://127.0.0.1:5001/table?loc=53.27528,-2.1271&loc=57.06322,-2.13991&loc=57.1913,-2.12272&loc=57.13205,-2.13559&loc=57.12008,-2.12476&loc=57.14234,-2.09557&loc=57.15555,-2.16155&loc=57.20477,-2.17626&loc=57.18151,-2.10008&loc=57.14901,-2.1&loc=57.15304,-2.13709&loc=57.14375,-2.1141&loc=57.14303,-2.11291&loc=57.14232,-2.11251&loc=57.13497,-2.12728&loc=57.14072,-2.12075&loc=57.12336,-2.13657&loc=57.12726,-2.11935&loc=57.14355,-2.10829&loc=57.13866,-2.09983&loc=57.13787,-2.08856&loc=57.13696,-2.0871&loc=57.10416,-2.08579&loc=57.06132,-2.12678&loc=57.06059,-2.12547

被截断为：

// http://127.0.0.1:5001/table?loc=53.27528,-2.1271&loc=57.06322,-2.13991&loc=57.1913,-2.12272&loc=57.13205,-2.13559&loc=57.12008,-2.12476&loc=57.14234,-2.09557&loc=57.15555,-2.16155&loc=57.20477,-2.17626&loc=57.18151,-2.10008&loc=57.14901,-2.1&loc=57.15304,-2.13709&loc=57.14375,-2.1141&loc=57.14303,-2.11291&loc=57.14232,-2.11251&loc=57.13497,-2.12728&loc=57.14072,-2.12075&loc=57.12336,-2.13657&loc=57.12726,-2.11935&loc=57.14355,-2.10829&loc=57.13866,-2.09983&loc=57.13787,-2.08856&loc=57.13696,-2.0871&loc=57.10416,-2

我想知道是否有其他方法可以让我向本地主机服务器发送请求？理想情况下，我想要与NA相同的功能，我可以给它一个由50,000个位置组成的矩阵，然后它在一天内(截止时间为20分钟)遍历它们--这样的事情可能吗？

Answer 1

很多库在处理HTTP请求时都会限制URL的长度。OSRM本身对URL长度没有限制。不过，有一个--max-table-locations参数需要更新。

也就是说，对于较大的请求，我建议使用我们的node-bindings或C++库like in this example。
