Clarifai：“格式错误或无效的请求”

Question

我有以下Python代码，它向Clarifai的人口统计端点发出POST请求：

import requests
import pprint

headers = {
    "Authorization": "Key MY_KEY",
    "Content-Type": "application/json"
}

data = {"inputs": [{"data": {"image": {"url": "https://samples.clarifai.com/demographics.jpg"}}}]}

proxies = {
    "http": "MY_HTTP_PROXY", 
    "https": "MY_HTTPS_PROXY"
}

response = requests.post('https://api.clarifai.com/v2/models/c0c0ac362b03416da06ab3fa36fb58e3/outputs', headers=headers, data=data, proxies=proxies, verify=False)

pprint.pprint(response.json())

请注意，我已经分别用MY_KEY、MY_HTTP_PROXY和MY_HTTPS_PROXY替换了我的真实MY_KEY和代理。

有没有使用过Clarifai的人知道我做错了什么？我在Clarifai自己的论坛上看到了一段example of working代码，但我看不出工作代码和我的有什么大的区别。

Answer 1

只需将传递的数据转换为json即可。

import requests
import pprint
import json

headers = {
    "Authorization": "Key MY_KEY",
    "Content-Type": "application/json"
}

data = {"inputs": [{"data": {"image": {"url": "https://samples.clarifai.com/demographics.jpg"}}}]}

json_data = json.dumps(data)

proxies = {
    "http": "MY_HTTP_PROXY", 
    "https": "MY_HTTPS_PROXY"
}

response = requests.post('https://api.clarifai.com/v2/models/c0c0ac362b03416da06ab3fa36fb58e3/outputs', headers=headers, data=json_data, proxies=proxies, verify=False)

pprint.pprint(response.json())

Answer 2

数据变量所需的引号

'data = {"inputs": [{"data": {"image": {"url": "https://samples.clarifai.com/demographics.jpg"}}}]}'
