This topic describes how to configure a proxy in Alibaba Cloud SDK V2.0.
Configuration method
Note
The proxy configurations take effect in the following descending order: the configuration by using the RuntimeOptions object and the configuration when you initialize an SDK client.
The following code provides examples on how to configure a proxy by using the RuntimeOptions object.
JavaScript
