Error in face detection and signature of Tencent cloud interface

First, you need to buy face detection API

I use face detection   If you buy face comparison or face recognition, their usage is basically the same, that is, the transmission parameters are different

It's simple

Let's talk about the pit that is easy to step on

I first looked at his documents I'll use it postman To detect this interface The parameters are transferred according to the following required parameters

And then all kinds of errors

Especially when adding people He said the signature was always wrong

The provided credentials could not be validated. Please check your signature

  Using it to generate a signature doesn't work

Finally, I found that there was a problem with the starting point Then I clicked on debugging to have a look

It is found that the code generation here can directly call That's the point I use it Python

  After copying these codes, the imported package will report an error Because I'm using python So we need to download Tencent cloud SDK Use python edition

pip install --upgrade tencentcloud-sdk-python

It's almost over here

You will find that you only need to copy and paste the interface of others

For example, we need to add people We just need to fill in the parameters

import json
from tencentcloud.common import credential
from tencentcloud.common.profile.client_profile import ClientProfile
from tencentcloud.common.profile.http_profile import HttpProfile
from tencentcloud.common.exception.tencent_cloud_sdk_exception import TencentCloudSDKException
from tencentcloud.iai.v20200303 import iai_client, models
try:
    cred = credential.Credential("AKIDPedLnysVrwlJbcNr40g4B1atvf8KFsFL", "yf5E6h26tQgeNoyrTpuiFWWEfqkMhkX3")
    httpProfile = HttpProfile()
    httpProfile.endpoint = "iai.tencentcloudapi.com"

    clientProfile = ClientProfile()
    clientProfile.httpProfile = httpProfile
    client = iai_client.IaiClient(cred, "ap-beijing", clientProfile)

    req = models.CreatePersonRequest()
    params = {
        "GroupId": " Fill in your warehouse name ",
        "PersonName": " Personnel to be entered name",
        "PersonId": " Personnel id",
        "Image":" picture bease64 Format  "
    }
    req.from_json_string(json.dumps(params))

    resp = client.CreatePerson(req)
    print(resp.to_json_string())

except TencentCloudSDKException as err:
    print(err)

You can put these corresponding codes into your code according to your business needs

It's over here. I hope you don't step on the pit
