requests.exceptions.HTTPError：404 客户端错误：找不到 url 的资源

如何解决requests.exceptions.HTTPError：404 客户端错误：找不到 url 的资源 | Azure 认知服务 API

我正在尝试通过 Azure Cognitive Service API 发送图像。我收到此错误消息： requests.exceptions.HTTPError：404 客户端错误：找不到 url 的资源：https://myfirstpythonapi.cognitiveservices.azure.com/analyze？ ...

# Use the requests library to simplify making a REST API call from Python 
import requests

# We will need the json library to read the data passed back 
# by the web service
import json

# You need to update the SUBSCRIPTION_KEY to 
# they key for your Computer Vision Service
SUBSCRIPTION_KEY = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

# You need to update the vision_service_address to the address of
# your Computer Vision Service
vision_service_address = "https://myfirstpythonapi.cognitiveservices.azure.com/"

# Add the name of the function you want to call to the address
address = vision_service_address + "analyze"

# According to the documentation for the analyze image function 
# There are three optional parameters: language,details & visualFeatures
parameters  = {'visualFeatures':'Description','language':'en'}

# Open the image file to get a file object containing the image to analyze
image_path = "c:/Users/PC[enter image description here][1]T/Desktop/CallApi/Dodge.jpg"
image_data = open(image_path,"rb").read()

# According to the documentation for the analyze image function
# we need to specify the subscription key and the content type
# in the HTTP header. Content-Type is application/octet-stream when you pass in a image directly
headers    = {'Content-Type': 'application/octet-stream','Ocp-Apim-Subscription-Key': SUBSCRIPTION_KEY}

# According to the documentation for the analyze image function
# we use HTTP POST to call this function
response = requests.post(address,headers=headers,params=parameters,data=image_data)

# Raise an exception if the call returns an error code
response.raise_for_status()

# display the JSON results returned
results = response.json()
print(json.dumps(results))

请帮帮我。我是菜鸟...

解决方法

您应该更改您的 vision_service_address。

如下图，

vision_service_address = "https://<your_region>.api.cognitive.microsoft.com/vision/v3.2/"

测试结果：

修改后的代码：

# Use the requests library to simplify making a REST API call from Python 

import requests

# We will need the json library to read the data passed back 
# by the web service
import json

# You need to update the SUBSCRIPTION_KEY to 
# they key for your Computer Vision Service
SUBSCRIPTION_KEY = "03****e"

# You need to update the vision_service_address to the address of
# your Computer Vision Service
vision_service_address = "https://centralus.api.cognitive.microsoft.com/vision/v3.2/"

# Add the name of the function you want to call to the address
address = vision_service_address + "analyze"

# According to the documentation for the analyze image function 
# There are three optional parameters: language,details & visualFeatures
parameters  = {'visualFeatures':'Description','language':'en'}

# Open the image file to get a file object containing the image to analyze
image_path = "E:\\MyCase\Dev\\Python\\faceapi2\\jason.jpg"
image_data = open(image_path,"rb").read()

# According to the documentation for the analyze image function
# we need to specify the subscription key and the content type
# in the HTTP header. Content-Type is application/octet-stream when you pass in a image directly
headers    = {'Content-Type': 'application/octet-stream','Ocp-Apim-Subscription-Key': SUBSCRIPTION_KEY}

# According to the documentation for the analyze image function
# we use HTTP POST to call this function
response = requests.post(address,headers=headers,params=parameters,data=image_data)

# Raise an exception if the call returns an error code
response.raise_for_status()

# Display the JSON results returned
results = response.json()
print(json.dumps(results))
