HTTP requests and SDK calls are two different ways to access API interfaces, and their differences are mainly in the following aspects:
Technical implementation: HTTP requests use the HTTP protocol for communication, and developers need to use HTTP client libraries or write their own HTTP requests** to achieve this. SDK calls use encapsulated API libraries or SDKs, and developers only need to call them according to the APIs provided by the SDK.
API invocation mode: HTTP requests are requested and responded to through the HTTP protocol, and developers generally need to construct the request data and parse the response data by themselves. SDK calls are made through the encapsulated API library, which generally only needs to pass in parameters, and the API library will automatically construct the request and parse the response.
Ease of use: It is more convenient to use the SDK to call API interfaces than to send HTTP requests directly, because the SDK already encapsulates many common API calls and error handling logic. However, using HTTP requests to call API interfaces requires developers to construct requests and parse responses by themselves, which takes more time and effort.
In short, HTTP requests and SDK calls are two different ways to access API interfaces, and the choice of which method depends on the specific application scenarios and development requirements. If the application needs to be developed quickly, you can choose to use the SDK to call the API interface. If you need more granular control over requests and responses, you can choose to use HTTP requests.
