使用 CMD_SKINS 的 Directadmin 上传徽标时出错，无法获取 mime-type

编程问答 2022-05-26

问题描述

我正在尝试使用 CMD_API_SKINS 上传自定义徽标

这是我使用 curl + bash 的完整代码：

#/bin/bash

# DA needs this path

mkdir -p /home/tmp

# Assume my logo file is already here:

default_logo_file_home="/home/tmp/logo.png"

# The logo file is set to nobody:nogroup

chown nobody:nogroup "${default_logo_file_home}"

## Setup query data for curl:

username="admin"

password="12321aa"

da_port="2222"

host_server="server.domain.com"

ssl="https"

skin_name="evolution"

command="CMD_API_SKINS"

data="action=upload_logo&file=${default_logo_file_home}&json=yes&name=${skin_name}&which=1"

method="POST"

curl --silent --request "${method}" --user "${username}":"${password}" --data "${data}" "${ssl}://${host_server}:${da_port}/${command}"

在调试这个 API 时，我得到了这样的错误：

text='An Error Occurred'

        result='Cannot get mime-type for log<br>

似乎 DA 正在尝试解析并获取文件“logo.png”的扩展名，但它不能

Command::doCommand(/CMD_API_SKINS) : finished

Command::run: finished /CMD_API_SKINS

我也尝试像这样对查询进行编码，但仍然出现相同的错误

default_logo_file_home="%2Fhome%2Ftmp%2Flogo%2Epng"
data="action=upload%5Flogo&file=${default_logo_file_home}&json=yes&name=${skin_name}&which=%31"

这里有什么解释吗？是否可以使用此 API 上传徽标？

解决方法

好的，我找到了没有在任何地方记录的技巧。上传的文件需要附加一个随机字符串。所以我改变了这个：

default_logo_file_home="/home/tmp/logo.png"

进入这个：

RANDOM_STR="EbYIES"

default_logo_file_home="/home/tmp/logo.png${RANDOM_STR}"

现在完美运行
