如何将自定义客户端传递给Golang oauth2.Exchange


The documentation for oauth2.Exchange at says:

The HTTP client to use is derived from the context. If a client is not provided via the context, http.DefaultClient is used.

Now I have created a http.Client with my own settings. How do I get the oauth2.Exchange function to use it?

    The oauth2 package defines the following variable:

    var HTTPClient internal.ContextKey

    HTTPClient is the context key to use with's WithValue function to associate an *http.Client value with a context.

    Use the above variable as the context key when constructing the context to pass to Exchange:

    client := &http.Client{
        // TODO
    parent := oauth2.NoContext()
    ctx := context.WithValue(parent, oauth2.HTTPClient, client)
    tkn, err := c.Exchange(ctx, code)
