exchange.SetBase

The exchange.SetBase() function is used to set the base address of the exchange API interface configured in the exchange exchange object.

    
    
    
exchange.SetBase(s)

Examples

    javascript
    
    
function main() {
    // 使用默认基地址
    Log(exchange.GetTicker())
    // 切换为https://aws.okx.com
    exchange.SetBase("https://aws.okx.com")
    Log(exchange.GetTicker())
}

    python
    
    
def main():
    Log(exchange.GetTicker())
    exchange.SetBase("https://aws.okx.com")
    Log(exchange.GetTicker())

    c++
    
    
void main() {
    Log(exchange.GetTicker());
    exchange.SetBase("https://aws.okx.com");
    Log(exchange.GetTicker());
}

Arguments

Remarks

Switching exchange API base addresses is not supported in the backtesting system, as the backtesting system is a sandbox simulation environment and does not actually access the exchange's API interfaces.

exchange.GetBase

The exchange.GetBase() function is used to get the base address of the current exchange API interface.

    
    
    
exchange.GetBase()

Examples

    javascript
    
    
function main() {
    Log(exchange.GetBase())
}

    python
    
    
def main():
    Log(exchange.GetBase())

    c++
    
    
void main() {
    Log(exchange.GetBase());
}

exchange.SetProxy

The exchange.SetProxy() function is used to set the proxy configuration for the exchange exchange object.

    
    
    
exchange.SetProxy(proxy)

Examples

• Configure socks5 proxy for exchange exchange object:

  • javascript
  • python
  • cpp

  
      javascript
      
      
  function main() {
      exchange.SetProxy("socks5://192.168.1.10:8080")
      // 如果访问不到交易所行情接口，设置一个可用的ss5代理，就可以访问到行情接口了
      Log(exchange.GetTicker())
  }
  

  
      python
      
      
  def main():
      exchange.SetProxy("socks5://192.168.1.10:8080")
      Log(exchange.GetTicker())
  

  
      c++
      
      
  void main() {
      exchange.SetProxy("socks5://192.168.1.10:8080");
      Log(exchange.GetTicker());
  }
  

• In addition to **globally specifying** the IP address for requests sent by the exchange exchange object, it also supports specifying IP addresses based on exchange:

  • javascript
  • python
  • cpp

  
      javascript
      
      
  function main(){
      exchange.SetProxy("ip://10.0.3.15")
      // 发出的请求IP地址为10.0.3.15
      exchange.GetTicker()
  }
  

  
      python
      
      
  def main():
      exchange.SetProxy("ip://10.0.3.15")
      exchange.GetTicker()
  

  
      c++
      
      
  void main() {
      exchange.SetProxy("ip://10.0.3.15");
      exchange.GetTicker();
  }
  

Arguments

Remarks

If the proxy setting fails, calling the exchange.SetProxy() function will return null.

The proxy setting functionality of the exchange.SetProxy() function only supports the rest protocol. Each exchange exchange object can set one proxy. After setting the proxy, all access to the exchange interface bound to the exchange exchange object will be accessed through the proxy.

Supports setting socks5 proxy, taking the first added exchange object exchange (i.e., exchanges[0]) as an example:

• Set proxy (no username, no password): exchange.SetProxy("socks5://127.0.0.1:8889").

• Set proxy (with username and password): exchange.SetProxy("socks5://username:[email protected]:8889"). Where username is the username and password is the password.

• Switch to normal mode (without proxy): exchange.SetProxy("").

Supports setting the IP address for requests sent by the exchange exchange object, global specification.

exchange.SetTimeout

The exchange.SetTimeout() function is used to set the rest request timeout for the exchange exchange object.

    
    
    
exchange.SetTimeout(timeout)

Examples

    javascript
    
    
function main() {
    exchange.SetTimeout(3000)
    Log(exchange.GetTicker())
}

    python
    
    
def main():
    exchange.SetTimeout(3000)
    Log(exchange.GetTicker())

    c++
    
    
void main() {
    exchange.SetTimeout(3000);
    Log(exchange.GetTicker());
}

Arguments

See Also

Remarks

The parameter timeout is a value in milliseconds, where 1000 milliseconds equals 1 second. It only applies to the rest protocol and is used to set the timeout for rest requests. It only needs to be set once to take effect. For example: exchange.SetTimeout(3000) sets the rest request timeout for the exchange exchange object to 3 seconds. When calling functions that involve network requests such as exchange.GetTicker(), if no response is received within 3 seconds, a timeout will occur, and the function call that times out will return a null value.

SetTimeout() is not a global function, but a method of the exchange exchange object.
