SDK for Go

Last updated: 2020-10-16 11:31:52

    SDK 3.0 is a companion tool for the TencentCloud API 3.0 platform. You can use all SMS APIs through the SDK. The new SDK version is unified and features the same SDK usage, API call methods, error codes, and returned packet formats for different programming languages.

    Note:

    • SMS sending APIs
      One message can be sent to up to 200 numbers at a time.
    • Signature and body template APIs
      Individual users have no permission to use signature and body template APIs and can manage SMS signatures and SMS body templates only in the SMS Console. To use the APIs, change "Individual Identity" to "Organizational Identity".

    Prerequisites

    • You have activated SMS. For detailed directions, please see Getting Started with Mainland China SMS.
    • If you need to send SMS messages in Mainland China, you need to purchase a Mainland China SMS package first.
    • You have prepared the dependent environment: Node.js 7.10.1 or above.
    • You have obtained the SecretID and SecretKey on the API Key Management page in the CAM Console.
      • SecretID is used to identify the API caller.
      • SecretKey is used to encrypt the string to sign that can be verified on the server. You should keep it private and avoid disclosure.
    • You have obtained the call address (endpoint). The call address of the SMS service is sms.tencentcloudapi.com.

    Relevant Documents

    • For more information on the APIs and their parameters, please see API Documentation.
    • You can download the SDK source code here.

    Installing SDK

    Installing through go get (recommended)

    You are recommended to install the SDK by using the tool that comes with the language:

     go get -u github.com/tencentcloud/tencentcloud-sdk-go

    Installing through source code

    1. Go to the GitHub code hosting page or quick download address to download the latest code.
    2. Decompress and install in the $GOPATH/src/github.com/tencentcloud directory.

    Sample Code

    Note:

    All samples are for reference only and cannot be directly compiled and executed. You need to modify them based on your actual needs. You can also use API 3.0 Explorer to automatically generate the demo code as needed.

    Each API has a corresponding request structure and a response structure. This document only lists the sample code of several common features. For more samples, please see SDK for Go Samples.
