Google.Cloud.Functions.V2Beta is a.NET client library for the Cloud Functions API.
Note: This documentation is for version 1.0.0-beta07 of the library. Some samples may not work with other versions.
Installation
Install the Google.Cloud.Functions.V2Beta package from NuGet. Add it to your project in the normal way (for example by right-clicking on the project in Visual Studio and choosing "Manage NuGet Packages..."). Please ensure you enable pre-release packages (for example, in the Visual Studio NuGet user interface, check the "Include prerelease" box). Some of the following samples might only work with the latest pre-release version (1.0.0-beta07) of Google.Cloud.Functions.V2Beta.
Authentication
When running on Google Cloud, no action needs to be taken to authenticate.
Otherwise, the simplest way of authenticating your API calls is to set up Application Default Credentials. The credentials will automatically be used to authenticate. See Set up Application Default Credentials for more details.
Create a client instance by calling the static Create or CreateAsync methods. Alternatively, use the builder class associated with each client class (e.g. FunctionServiceClientBuilder for FunctionServiceClient) as an easy way of specifying custom credentials, settings, or a custom endpoint. Clients are thread-safe, and we recommend using a single instance across your entire application unless you have a particular need to configure multiple client objects separately.
Using the REST (HTTP/1.1) transport
This library defaults to performing RPCs using gRPC using the binary Protocol Buffer wire format. However, it also supports HTTP/1.1 and JSON, for situations where gRPC doesn't work as desired. (This is typically due to an incompatible proxy or other network issue.) To create a client using HTTP/1.1, specify a RestGrpcAdapter reference for the GrpcAdapter property in the client builder. Sample code:
var client = new FunctionServiceClientBuilder { GrpcAdapter = RestGrpcAdapter.Default }.Build();
