## Как это использовать?
|
||
Перед получением `OkHttpClient` необходимо инициализировать настройки игнорирования сертификатов. Для этого вызываем метод:
|
||
|
||
```java
|
||
OkHttpUtil.init(true);
|
||
```
|
||
|
||
После этого можете получить `OkHttpClient`:
|
||
|
||
```java
|
||
OkHttpUtil.getClient();
|
||
```
|
||
|
||
Или вот так:
|
||
|
||
```java
|
||
public class HttpParse {
|
||
|
||
static {
|
||
OkHttpUtil.init(true);
|
||
}
|
||
|
||
private static final OkHttpClient client = OkHttpUtil.getClient();
|
||
|
||
// ... ... ... ... ...
|
||
|
||
}
|
||
``` |
