將angular2中的兩個URL合併成一個 - ionic2

Question

我試圖將兩個url合併成一個url。

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

而且我有來自API的路徑"/samples/leads/Import_Leads_Sample.csv"的文件。我在一個標以此爲filepath現在文件路徑持有

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

我想這兩者進行組合，形成一個網址。

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

Answer 1

將文件路徑存儲在變量中併合並這兩個變量。

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
