当图片转换为base64编码字符串后，其中包含大量的+号，如果我们将上述base64编码字符串通过网络传输给其他接口，那么服务器在解析数据时会把+号当成连接符，然后自动将+号转换为空格，所以为保证数据的准确性，我们需要将空格转换成+号，转换方法如下：
base32_val[j]='\0';free(bin_dump);while(strlen(base32_val)%4!=0)/*inserts '=' at the end of the base64 encoded string until the length is in the multiplication of 4.*/insert(base32_val, strlen(base32_val),0x3d, strlen(base32_val), base32_val_space); strcpy(outdata,base32...
