资源说明：The purpose of this book is to teach solid idiomatic Go programming using
all the features the language provides, as well as the most commonly used Go
packages from Go’s standard library. The book is also designed to serve as a
useful reference once the language is learned. To meet both of these goals the
book is quite comprehensive and tries to cover every topic in just one place—and
with forward and backward cross-references throughout.
Go is quite C-like in spirit, being a small and efficient language with convenient
low-level facilities such as pointers. Yet Go also offers many features associated
with high- or very high-level languages, such as Unicode strings, powerful builtin
data structures, duck typing, garbage collection, and high-level concurrency
support that uses communication rather than shared data and locks. Go also
has a large and wide-ranging standard library.
The reader is assumed to have programming experience in a mainstream programming
language such as C,C++, Java, Python, or similar, although all of Go’s
unique features and idioms are illustrated with complete runnable examples
that are fully explained in the text.
To successfully learn any programming language it is necessary to write programs
in that language. To this end the book’s approach is wholly practical, and
readers are encouraged to experiment with the examples, try the exercises, and
write their own programs to get hands-on experience. As with all my previous
books, the quoted code snippets are of “live code”; that is, the code was automatically
extracted from .go source files and directly embedded in the PDF that
went to the publisher—so there are no cut and paste errors, and the code works.
Wherever possible, small but complete programs and packages are used as examples
to provide realistic use cases. The examples, exercises, and solutions are
available online at www.qtrac.eu/gobook.html.
The book’s key aim is to teach the Go language, and although many of the
standard Go packages are used, not all of them are. This is not a problem, since
reading the book will provide enough Go knowledge for readers to be able to
make use of any of the standard packages, or any third-
