Clarifai API体验

Research

参考官方给出的文档：https://developer.clarifai.com/guide/tag#guide-tag-responses，在本机进行简单的体验。

首先注册账户，然后创建Application，获取ID及Secret，并在Application页面下生成“Access Token”码：XXx2QXEzmXXfj1eXkXXXUFLYXXX7DX

〇、客户端API参考：https://github.com/Clarifai/clarifai-python

pip install clarifai==2.0.10
clarifai config
CLARIFAI_APP_ID:
CLARIFAI_APP_SECRET:

在python中实现测试：

from clarifai.rest import ClarifaiApp
app = ClarifaiApp()
model = app.models.get('general-v1.3')
print model.predict_by_url('https://samples.clarifai.com/metro-north.jpg')
# or local image
print model.predict_by_filename('/Users/USER/my_image.jpeg')

一、打开MAC终端，输入Request命令：

  1. 测试在线图片

    curl "https://api.clarifai.com/v1/tag/" \
      -X POST --data-urlencode "url=https://samples.clarifai.com/metro-north.jpg" \
      -H "Authorization: Bearer XXx2QXEzmXXfj1eXkXXXUFLYXXX7DX"

  2. 测试本地图片

    curl "https://api.clarifai.com/v1/tag/" \
      -X POST -F "encoded_data=@/Users/USER/my_image.jpeg" \
      -H "Authorization: Bearer XXx2QXEzmXXfj1eXkXXXUFLYXXX7DX"

  3. 测试多幅图像

    curl "https://api.clarifai.com/v1/tag/" \
      -X POST -F "encoded_data=@/Users/USER/my_image1.jpeg" \
      -F "encoded_data=@/Users/USER/my_image2.jpeg" \
      -F "encoded_data=@/Users/USER/my_image3.jpeg" \
      -F "encoded_data=@/Users/USER/my_image4.jpeg" \
      -H "Authorization: Bearer XXx2QXEzmXXfj1eXkXXXUFLYXXX7DX"

二、读取Response结果

在python中使用json来解析文本结果：

# -*- coding: utf-8 -*-
import json
for line in open("response.txt"):
    print line
str=json.loads(line)
results=str['results']
strNum=len(str['results'])
for ind in range(0,strNum):
    print ind
    print results[ind]['result']['tag']['classes']

输出解析结果（图像的tag类别）：
