Check if a jpg/jpeg image is corrupt with Pillow

Here is a short code example to check if a jpg/jpeg have their ending bytes or if the file is incomplete or corrupt.

from PIL import Image

def verify_jpeg_image(file_path):
    try:
        img = Image.open(file_path)
        img.getdata()[0]
    except OSError:
        return False
    return True

I have seen solutions using scikit-image, but if you don't need scikit-image to do anything else, you can go for the library that scikit-image uses instead. This way you get fewer dependencies.

Using proxy with GraphQL.Client in C#

Here is a short snippet how to set up proxy with GraphQL.Client in C#. In this example I use a local proxy for debugging.

var proxy = new WebProxy
{
    Address = new Uri($"http://127.0.0.1:8888"),
};

var httpClientHandler = new HttpClientHandler
{
    Proxy = proxy,
};

var options = new GraphQLHttpClientOptions
{
    EndPoint = new Uri("https://test.com/graphql"),
    HttpMessageHandler = httpClientHandler
};

var graphQLClient = new GraphQLHttpClient(
    options,
    new NewtonsoftJsonSerializer()
);
