Then, to perform the actual encoding, we need to call the base64_encode function. As first input, this function receives the string to encode, which we have previously declared. Note however that the function e
In order to apply the base64 encoding to the previously declared string, we simply need to call the encode method of the base64 class. This method receives as input the string we want to encode and returns thebase64encoded result, also as a string. Note however that the encode method is...

这里根据api调用文档的格式进行打包,需要注意的是len为原始的数据大小,不是base64编码后的数据大小。// Base64 encode audio data encode_base64(audioData, audioDataSize, audioDataBase64); memset(data_json, '\0', data_json_len); strcat(data_json, "{"); strcat(data_json, "\"format\":\"pcm\...
