二、准备
1、首先要去官网注册一个账号并登录。
2、在官网首页左侧导航栏有API开发平台的菜单，点击进去，记得先登录账号。
3、点击进去会看到两个使用api平台需要用到的key，把这两个key复制出来保存好。
三、主要步骤：
1、获取AccessKey与SecretKey
2、使用秘钥，获取网址必要的参数
3、请求网址，基于文生图参数，获取任务id
4、请求网址，基于任务id，获取图片网址
四、具体操作
1、接口网址
Liblib开放平台域名：https://openapi.liblibai.cloud（无法直接打开，需配合密钥访问）
2、生成API密钥
在登录Liblib领取API试用积分或购买API积分后，Liblib会生成开放平台访问密钥，用于后续API接口访问，密钥包括：
- AccessKey，API访问凭证，唯一识别访问用户，长度通常在20-30位左右，如：KIQMFXjHaobx7wqo9XvYKA
- SecretKey，API访问密钥，用于加密请求参数，避免请求参数被篡改，长度通常在30位以上，如：KppKsn7ezZxhi6lIDjbo7YyVYzanSu2d
3、使用密钥获取网址必要的参数
申请API密钥之后，需要在每次请求API接口的查询字符串中固定传递以下参数：
4、Python生成密码代码：
# 请求API接口的uri地址
text2img_uri = "/api/generate/webui/text2img"
def make_sign(uri):
"""
生成签名
"""
# 当前毫秒时间戳
timestamp = str(int(time.time() * 1000))
# 随机字符串
signature_nonce = str(uuid.uuid4()).replace('-', '')
# 拼接请求数据
content = '&'.join((uri, timestamp, signature_nonce))
# 生成签名
digest = hmac.new(SECRET_KEY.encode(), content.encode(), sha1).digest()
# 移除为了补全base64位数而填充的尾部等号
sign = base64.urlsafe_b64encode(digest).rstrip(b'=').decode()
return sign, timestamp, signature_nonce
注意：uri要与调用的接口保持一致
5、Python调用接口代码：
def call_liblibai_api():
generateUuid = ""
# 生成签名
sign, timestamp, signature_nonce = make_sign(text2img_uri)
# 准备请求参数
uri = 'https://openapi.liblibai.cloud/api/generate/webui/text2img' # 根据API地址更新uri
uri = f"{uri}?AccessKey={ACCESS_KEY}&Signature={sign}&Timestamp={timestamp}&SignatureNonce={signature_nonce}"
print(uri)
headers = {
'Content-Type': 'application/json'
}
data = {
"templateUuid": "e10adc3949ba59abbe56e057f20f883e",
"generateParams": {
"checkPointId": "ba34a22f1c044472a42b6051aac2afb3",
"prompt": "This is a 12-story hospital building. The ground floor houses the emergency room and pharmacy. The entrance is spacious and has a sheltered structure. Each floor from the second to the twelfth floor has a ward area, including a nurse station, ward Windows, and space for placing medical equipment. The building's exterior is simple, with Windows arranged regularly. From the outside, a clear 12-story structure can be seen.",
"negativePrompt": "ng_deepnegative_v1_75t,(badhandv4:1.2),EasyNegative,(worst quality:2),",
"sampler": 15,
"steps": 20,
"cfgScale": 7,
"width": 768,
"height": 1024,
"imgCount": 1,
"randnSource": 0,
"seed": 2228967414,
"restoreFaces": 0,
"hiResFixInfo": {
"hiresSteps": 20,
"hiresDenoisingStrength": 0.75,
"upscaler": 10,
"resizedWidth": 1024,
"resizedHeight": 1536
}
}
}
try:
# 发送POST请求
response = requests.post(uri, headers=headers, data=json.dumps(data))
# 处理响应
if response.status_code == 200:
result = response.json()
generateUuid = result['data']['generateUuid']
print('API调用成功，返回结果：', result)
else:
print('API调用失败，状态码：', response.status_code, '，响应内容：', response.text)
except requests.exceptions.RequestException as e:
print('请求异常：', e)
return generateUuid注意：具体参数说明，请参考开发文档
6、接口返回示例，获取任务id：
{
"code": 0,
"msg": "",
"data": {
"generateUuid": "8dcbfa2997444899b71357ccb7db378b"
}
}7、Python查看任务，并得到图片地址：
def get_cd_laowang_img(generateUuid):
result = {}
# 生成签名
sign, timestamp, signature_nonce = make_sign(generate_webui_status_uri)
# 准备请求参数
uri = 'https://openapi.liblibai.cloud/api/generate/webui/status' # 根据API地址更新uri
uri = f"{uri}?AccessKey={ACCESS_KEY}&Signature={sign}&Timestamp={timestamp}&SignatureNonce={signature_nonce}"
print(uri)
headers = {
'Content-Type': 'application/json'
}
data = {
"generateUuid": generateUuid,
}
try:
# 发送POST请求
response = requests.post(uri, headers=headers, data=json.dumps(data))
# 处理响应
if response.status_code == 200:
result = response.json()
print('API调用成功，返回结果：', result)
else:
print('API调用失败，状态码：', response.status_code, '，响应内容：', response.text)
except requests.exceptions.RequestException as e:
print('请求异常：', e)
return result注意：因为api接口改变，所以需要再次生成签名
