ספריות הלקוח של Routes API

בדף הזה נסביר איך להתחיל להשתמש בספריות הלקוח של Routes API.

מידע נוסף על ספריות הלקוח זמין במאמר הסבר על ספריות לקוח.

התקנת ספריית הלקוח

Java

מידע נוסף זמין במאמר הגדרת סביבת פיתוח ב-Java.

למידע נוסף, ראו לקוח Google Routes API ל-Java לקבלת הוראות ההתקנה.

Go

go get cloud.google.com/go/maps

מידע נוסף זמין במאמר הבא: הגדרת סביבת פיתוח של Go.

למידע נוסף, אפשר לקרוא את המאמר לקוח Google Routes API for Go לקבלת הוראות ההתקנה.

Node.js

npm install @googlemaps/routing

מידע נוסף זמין במאמר הגדרת סביבת פיתוח ב-Node.js.

להוראות ההתקנה המלאות, ראו לקוח Google Routes API ל-Node.js

Python

מידע נוסף זמין במאמר הבא: הגדרת סביבת פיתוח Python

להוראות ההתקנה המלאות, ראו לקוח Google Routes API ל-Python.

.Net

מידע נוסף זמין במאמר הבא: הגדרת סביבת פיתוח .Net

הוראות ההתקנה המלאות מפורטות במאמר לקוח Google Routes API ל-‎.NET

הגדרת אימות

כשמשתמשים בספריות לקוח, צריך להשתמש Application Default Credentials (ADC) לאימות. למידע נוסף על ההגדרה של ADC, מספקים פרטי כניסה ל-Application Default Credentials. במאמר אימות באמצעות ספריות לקוח תוכלו לקרוא מידע נוסף על שימוש ב-ADC עם ספריות לקוח.
