Go SDK installation and usage
The Go SDK currently only supports Linux and macOS
The SDK only offers to identify the content of a specified section of the file, identifying all the content of the entire file requires traversing the entire file

Adding dynamic libraries
​
1. Add the path where the dynamic library is located to the environment variable (temporary)
1
# Add environment variables
2
# Replace acrcloud_dlib_path with libacrcloud_extr_tool.so
3
$ LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/acrcloud_dlib_path/
4
$ export LD_LIBRARY_PATH
Copied!
2. Place the dynamic library in the same directory as your generated go binary program (temporary)
The most convenient way
3. Adding dynamic libraries to the system (permanently)
The following commands all require root privileges to run
1
# donwload the lib
2
$ sudo curl -fsSL https://raw.githubusercontent.com/acrcloud/acrcloud_sdk_golang/master/linux/x86-64/acrcloud/libacrcloud_extr_tool.so -o /usr/local/lib/libacrcloud_extr_tool.so
3
# Creating dynamic library configuration files
4
$ sudo bash -c "echo /usr/local/lib > /etc/ld.so.conf.d/acrcloud.conf"
5
# Update system configuration
6
$ sudo ldconfig
Copied!
Use go get to get the SDK
1
$ go get github.com/acrcloud/acrcloud_sdk_golang/acrcloud
Copied!
Initialization
First go to ACRCloud Developer Platform Console > Audio & Video Recognition to get Access Key, Access Secret and Host.
The obtained configuration information is then imported into ACRCloudRecognizer and initialized.
