• authorization：调用 API 的密钥，申请之后可以直接下拉选择。

Request Body 包括：

• image_url：上传的图片文件地址。

设置如下图所示：

代码示例

可以发现，在页面右侧已经自动生成了各种语言的代码，如图所示：

部分代码示例如下：

CURL

curl -X POST 'https://api.acedata.cloud/midjourney/describe' \
-H 'accept: application/json' \
-H 'authorization: Bearer {token}' \
-H 'content-type: application/json' \
-d '{
  "image_url": "https://cdn.acedata.cloud/kg7xp3.png"
}'

Python

import requests

url = "https://api.acedata.cloud/midjourney/describe"

headers = {
    "accept": "application/json",
    "authorization": "Bearer {token}",
    "content-type": "application/json"
}

payload = {
    "image_url": "https://cdn.acedata.cloud/kg7xp3.png"
}

response = requests.post(url, json=payload, headers=headers)
print(response.json())

响应示例

请求成功后，API 将返回图片的 4 条描述信息。例如：

{
  "descriptions": [
    "A cross-shaped road sign stands in the middle of an outdoor park, surrounded by trees and grasslands. The background is sunny with warm colors. There is sunlight shining through the leaves onto part of it. On one side of that street post there was also another sign with the lettering \"Kunming Park\", which looked very beautiful. This photo shows how wonderful nature can be. It gives people feelings like relaxation or tranquility in the style of nature. --ar 75:44",
    "A photo of a \"K鬥\" road sign in the park, with trees and grass on both sides. In front is a light yellow metal pole with two signs attached to it. The background features sunlight shining through green leaves onto one side of the street, creating a warm atmosphere. There is also water mist floating around. It was taken in the style of Sony A7R IV camera using Leica M lens. This scene conveys tranquility and harmony between nature and human creation. --ar 75:44",
    "A cross-shaped street sign stands in the middle of an open park, surrounded by trees and grassland. The sun shines through the leaves on part of it, creating a warm light effect. In front is a road leading to another green space. There's also some information about \"Inside Shilin Park\" on one side of that post. This scene gives people feelings of tranquility and harmony with nature. Natural lighting, 3D rendering in the style of Unreal Engine, Realistic photography style. --ar 75:44",
    "A cross-shaped signpost stands in the park, surrounded by lush trees and vibrant green grass under sunlight. Signs say \"VIDEO ANNattacks\" in an unknown language, creating an atmosphere of mystery and intrigue. The scene is captured with high-definition photography using Canon EOS R5 cameras, presenting a stunning visual effect that showcases intricate details in the style of modern photography. --ar 75:44"
  ]
}

可以看到，结果中有一个 descriptions 字段，里面包含了四个结果，每个结果都是一个候选的描述内容。
