将angular2中的两个URL合并成一个 - ionic2

Question

我试图将两个url合并成一个url。

let url = "http://example.com/public/"; 

而且我有来自API的路径"/samples/leads/Import_Leads_Sample.csv"的文件。我在一个标以此为filepath现在文件路径持有

filepath: "/samples/leads/Import_Leads_Sample.csv" 

我想这两者进行组合，形成一个网址。

let url = "http://example.com/public/samples/leads/Import_Leads_Sample.csv" 

Answer 1

将文件路径存储在变量中并合并这两个变量。

let url = "http://example.com/public/"; 
let filepath = Object.filepath; // equals "/samples/leads/Import_Leads_Sample.csv" 

let finalUrl = url + filepath.substr(1); // substr(1) to remove the '/' and avoid having a final url with '//' in it
