通过REST API上传图片或者其余媒体文件。

#这是第一种方式
import requests
import base64

# Credentials and endpoint
username = "website_user_name_loginName" #real user name, not the application name. 注意这里的用户名是登陆的用户名。
password = "user_profile_application_password$" #Dashboard->User->Profile->Application Passwords，注意这里的密码是应用密码，不是登陆密码
api_url = 'https://your_website_domain_name.xxxxxxx/wp-json/wp/v2/media'

# File path
file_path = 'test.webp'


# Open the file and read its binary data
with open(file_path, 'rb') as file:
    file_data = file.read()
# Headers for the request
headers = {
    'Authorization': 'Basic ' + base64.b64encode(f'{username}:{password}'.encode()).decode(),
    'Accept': 'application/json',  # The API returns JSON
    'Content-Type': 'application/binary',  # Set content type to binary
    'Content-Disposition': f'attachment; filename={file_path.split("/")[-1]}'  # Set file name
}

# Make the POST request
response = requests.post(api_url, headers=headers, data=file_data)

# Check the response
if response.status_code == 201:  # 201 Created
    print("Upload successful!")
    print("Response:", response.json())
else:
    print(f"Failed to upload. Status code: {response.status_code}")
    print("Response:", response.text)


# Assuming 'response' is the Response object from requests
try:
    # Parse JSON from the response
    response_data = response.json()

    # Extract the uploaded image URL
    uploaded_image_url = response_data.get("source_url", None)

    # Print the URL
    if uploaded_image_url:
        print(f"Uploaded Image URL: {uploaded_image_url}")
    else:
        print("Image URL not found in the response.")
except Exception as e:
    print(f"An error occurred: {e}")

第二种方式，可以设置图片的Title、ALT等

#第二种方式，这个方式可以设置图片的Alt
import requests
import base64


# Credentials and endpoint
username = "login_user_name" #real user name, not the application name
password = "application_password" #Dashboard->User->Profile->Application Passwords
#upload media endpoint
host = 'https://your_domain_name.xxxxx/wp-json/wp/v2/media'

# Authentication using Basic Auth
auth = (username, password)

# File path
file_path = 'test.webp'

# Metadata for the upload
data = {
    "status": "draft",
    "title": "Photo media",
    "description": "Photo media",
    "media_type": "image",
    "alt_text": "alternate text"
}

try:
    # Read the image file in binary mode
    with open(file_path, 'rb') as img_file:
        file_data = img_file.read()

    # Prepare headers
    headers = {
        'Content-Type': 'image/webp',
        'Content-Disposition': f'attachment; filename="{file_path.split("/")[-1]}"',
    }

    # Make the POST request
    response = requests.post(
        host,
        auth=auth,
        headers=headers,
        data=file_data,
        params=data  # Additional metadata as query params
    )

    # Handle response
    if response.status_code == 201:
        print("Upload successful!")
        print("Response:", response.json())
    else:
        print(f"Failed to upload. Status code: {response.status_code}")
        print("Response:", response.text)

except Exception as e:
    print(f"An error occurred: {e}")



# Assuming 'response' is the Response object from requests
try:
    # Parse JSON from the response
    response_data = response.json()

    # Extract the uploaded image URL
    uploaded_image_url = response_data.get("source_url", None)

    # Print the URL
    if uploaded_image_url:
        print(f"Uploaded Image URL: {uploaded_image_url}")
    else:
        print("Image URL not found in the response.")
except Exception as e:
    print(f"An error occurred: {e}")

WordPress上传图片以后，会自动生成不同尺寸的图片，比如上传的是dog.jpg, 可能会生成dog-600*600.jpg, dog-300*300.jpg, 本来一张图片只有100KB，但是自动生成了好几张，存储空间可能就翻倍了。如果不需要自动生成，可以使用如下代码，放到theme->function.php文件中


function disable_image_sizes_for_rest_api($sizes) {
    // 检查是否通过 REST API 上传图片
    if (defined('REST_REQUEST') && REST_REQUEST) {
        return []; // 禁止生成任何额外尺寸
    }
    return $sizes; // 非 REST API 上传仍正常处理
}
add_filter('intermediate_image_sizes_advanced', 'disable_image_sizes_for_rest_api');
