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 expects a const unsigned char pointer, which means that we need to do a cast on...

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\...
