在下文中一共展示了Config函数的10个代码示例,这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞,您的评价将有助于系统推荐出更棒的Golang代码示例。

示例1: New

// New creates a new instance of the handlers merging in the provided configs
// on top of the SDK's default configurations. Once the Session is created it
// can be mutated to modify the Config or Handlers. The Session is safe to be
// read concurrently, but it should not be written to concurrently.
//
// If the AWS_SDK_LOAD_CONFIG environment is set to a truthy value, the New
// method could now encounter an error when loading the configuration. When
// The environment variable is set, and an error occurs, New will return a
// session that will fail all requests reporting the error that occured while
// loading the session. Use NewSession to get the error when creating the
// session.
//
// If the AWS_SDK_LOAD_CONFIG environment variable is set to a truthy value
// the shared config file (~/.aws/config) will also be loaded, in addition to
// the shared credentials file (~/.aws/config). Values set in both the
// shared config, and shared credentials will be taken from the shared
// credentials file.
//
// Deprecated: Use NewSession functiions to create sessions instead. NewSession
// has the same functionality as New except an error can be returned when the
// func is called instead of waiting to receive an error until a request is made.
func New(cfgs ...*aws.Config) *Session {
	// load initial config from environment
	envCfg := loadEnvConfig()

	if envCfg.EnableSharedConfig {
		s, err := newSession(envCfg, cfgs...)
		if err != nil {
			// Old session.New expected all errors to be discovered when
			// a request is made, and would report the errors then. This
			// needs to be replicated if an error occurs while creating
			// the session.
			msg := "failed to create session with AWS_SDK_LOAD_CONFIG enabled. " +
				"Use session.NewSession to handle errors occuring during session creation."

			// Session creation failed, need to report the error and prevent
			// any requests from succeeding.
			s = &Session{Config: defaults.Config()}
			s.Config.MergeIn(cfgs...)
			s.Config.Logger.Log("ERROR:", msg, "Error:", err)
			s.Handlers.Validate.PushBack(func(r *request.Request) {
