## Build and Install
go get:
```sh
go get github.com/denverdino/aliyungo
```
## Test ECS
Modify "ecs/config_test.go"
```sh
TestAccessKeyId = "MY_ACCESS_KEY_ID"
TestAccessKeySecret = "MY_ACCESS_KEY_ID"
TestInstanceId = "MY_INSTANCE_ID"
TestIAmRich = false
```
* TestAccessKeyId: the Access Key Id
* TestAccessKeySecret: the Access Key Secret.
* TestInstanceId: the existing instance id for testing. It will be stopped and restarted during testing.
* TestIAmRich(Optional): If it is set to true, it will perform tests to create virtual machines and disks under your account. And you will pay the bill. :-)
Under "ecs" and run
```sh
go test
```
## Test OSS
Modify "oss/config_test.go"
```sh
TestAccessKeyId = "MY_ACCESS_KEY_ID"
TestAccessKeySecret = "MY_ACCESS_KEY_ID"
TestRegion = oss.Beijing
TestBucket = "denverdino"
```
* TestAccessKeyId: the Access Key Id
* TestAccessKeySecret: the Access Key Secret.
* TestRegion: the region of OSS for testing
* TestBucket: the bucket name for testing
Under "oss" and run
```sh
go test
```

[![Build Status](https://travis-ci.org/digitalocean/godo.svg)](https://travis-ci.org/digitalocean/godo)
# Godo
Godo is a Go client library for accessing the DigitalOcean V2 API.
You can view the client API docs here: [http://godoc.org/github.com/digitalocean/godo](http://godoc.org/github.com/digitalocean/godo)
You can view DigitalOcean API docs here: [https://developers.digitalocean.com/documentation/v2/](https://developers.digitalocean.com/documentation/v2/)
## Usage
```go
import "github.com/digitalocean/godo"
```
Create a new DigitalOcean client, then use the exposed services to
access different parts of the DigitalOcean API.
### Authentication
Currently, Personal Access Token (PAT) is the only method of
authenticating with the API. You can manage your tokens
at the DigitalOcean Control Panel [Applications Page](https://cloud.digitalocean.com/settings/applications).
You can then use your token to create a new client:
```go
import "golang.org/x/oauth2"
pat := "mytoken"
type TokenSource struct {
AccessToken string
}
func (t *TokenSource) Token() (*oauth2.Token, error) {
token := &oauth2.Token{
AccessToken: t.AccessToken,
}
return token, nil
}
tokenSource := &TokenSource{
AccessToken: pat,
}
oauthClient := oauth2.NewClient(context.Background(), tokenSource)
client := godo.NewClient(oauthClient)
```
## Examples
To create a new Droplet:
```go
dropletName := "super-cool-droplet"
createRequest := &godo.DropletCreateRequest{
Name: dropletName,
Region: "nyc3",
Size: "512mb",
Image: godo.DropletCreateImage{
Slug: "ubuntu-14-04-x64",
},
}
ctx := context.TODO()
newDroplet, _, err := client.Droplets.Create(ctx, createRequest)
if err != nil {
fmt.Printf("Something bad happened: %s\n\n", err)
return err
}
```
### Pagination
If a list of items is paginated by the API, you must request pages individually. For example, to fetch all Droplets:
```go
func DropletList(ctx context.Context, client *godo.Client) ([]godo.Droplet, error) {
// create a list to hold our droplets
list := []godo.Droplet{}
// create options. initially, these will be blank
opt := &godo.ListOptions{}
for {
droplets, resp, err := client.Droplets.List(ctx, opt)
if err != nil {
return nil, err
}
// append the current page's droplets to our list
for _, d := range droplets {
list = append(list, d)
}
// if we are at the last page, break out the for loop
if resp.Links == nil || resp.Links.IsLastPage() {
break
}
page, err := resp.Links.CurrentPage()
if err != nil {
return nil, err
}
// set the page we want for the next request
opt.Page = page + 1
}
return list, nil
}
```
## Versioning
Each version of the client is tagged and the version is updated accordingly.
Since Go does not have a built-in versioning, a package management tool is
recommended - a good one that works with git tags is
[gopkg.in](http://labix.org/gopkg.in).
To see the list of past versions, run `git tag`.
## Documentation
For a comprehensive list of examples, check out the [API documentation](https://developers.digitalocean.com/documentation/v2/).
For details on all the functionality in this library, see the [GoDoc](http://godoc.org/github.com/digitalocean/godo) documentation.

We love pull requests! Please see the [contribution guidelines](CONTRIBUTING.md).

/*
Equal returns true iff protocol buffers a and b are equal.
The arguments must both be pointers to protocol buffer structs.
Equality is defined in this way:
- Two messages are equal iff they are the same type,
corresponding fields are equal, unknown field sets
are equal, and extensions sets are equal.
- Two set scalar fields are equal iff their values are equal.
If the fields are of a floating-point type, remember that
NaN != x for all x, including NaN. If the message is defined
in a proto3 .proto file, fields are not "set"; specifically,
zero length proto3 "bytes" fields are equal (nil == {}).
- Two repeated fields are equal iff their lengths are the same,
and their corresponding elements are equal. Note a "bytes" field,
although represented by []byte, is not a repeated field and the
rule for the scalar fields described above applies.
- Two unset fields are equal.
- Two unknown field sets are equal if their current
encoded state is equal.
- Two extension sets are equal iff they have corresponding
elements that are pairwise equal.
- Two map fields are equal iff their lengths are the same,
and they contain the same set of elements. Zero-length map
fields are equal.
- Every other combination of things are not equal.
The return value is undefined if a and b are not protocol buffers.

Package proto converts data structures to and from the wire format of
protocol buffers. It works in concert with the Go source code generated
for .proto files by the protocol compiler.
A summary of the properties of the protocol buffer interface
for a protocol buffer variable v:
- Names are turned from camel_case to CamelCase for export.
- There are no methods on v to set fields; just treat
them as structure fields.
- There are getters that return a field's value if set,
and return the field's default value if unset.
The getters work even if the receiver is a nil message.
- The zero value for a struct is its correct initialization state.
All desired fields must be set before marshaling.
- A Reset() method will restore a protobuf struct to its zero state.
- Non-repeated fields are pointers to the values; nil means unset.
That is, optional or required field int32 f becomes F *int32.
- Repeated fields are slices.
- Helper functions are available to aid the setting of fields.
msg.Foo = proto.String("hello") // set field
- Constants are defined to hold the default values of all fields that
have them. They have the form Default_StructName_FieldName.
Because the getter methods handle defaulted values,
direct use of these constants should be rare.
- Enums are given type names and maps from names to values.
Enum values are prefixed by the enclosing message's name, or by the
enum's type name if it is a top-level enum. Enum types have a String
method, and a Enum method to assist in message construction.
- Nested messages, groups and enums have type names prefixed with the name of
the surrounding message type.
- Extensions are given descriptor names that start with E_,
followed by an underscore-delimited list of the nested messages
that contain it (if any) followed by the CamelCased name of the
extension field itself. HasExtension, ClearExtension, GetExtension
and SetExtension are functions for manipulating extensions.
- Oneof field sets are given a single field in their message,
with distinguished wrapper types for each possible field value.
- Marshal and Unmarshal are functions to encode and decode the wire format.
When the .proto file specifies `syntax="proto3"`, there are some differences:
- Non-repeated fields of non-message type are values instead of pointers.
- Enum types do not get an Enum method.
The simplest way to describe this is to see an example.
Given file test.proto, containing
package example;
enum FOO { X = 17; }
message Test {
required string label = 1;
optional int32 type = 2 [default=77];

// Values returns the url.Values encoding of v.
//
// Values expects to be passed a struct, and traverses it recursively using the
// following encoding rules.
//
// Each exported struct field is encoded as a URL parameter unless
//
// - the field's tag is "-", or
// - the field is empty and its tag specifies the "omitempty" option
//
// The empty values are false, 0, any nil pointer or interface value, any array
// slice, map, or string of length zero, and any time.Time that returns true
// for IsZero().
//
// The URL parameter name defaults to the struct field name but can be
// specified in the struct field's tag value. The "url" key in the struct
// field's tag value is the key name, followed by an optional comma and
// options. For example:
//
// // Field is ignored by this package.
// Field int `url:"-"`
//
// // Field appears as URL parameter "myName".
// Field int `url:"myName"`
//
// // Field appears as URL parameter "myName" and the field is omitted if
// // its value is empty
// Field int `url:"myName,omitempty"`
//
// // Field appears as URL parameter "Field" (the default), but the field
// // is skipped if empty. Note the leading comma.
// Field int `url:",omitempty"`
//
// For encoding individual field values, the following type-dependent rules
// apply:
//
// Boolean values default to encoding as the strings "true" or "false".
// Including the "int" option signals that the field should be encoded as the
// strings "1" or "0".
//
// time.Time values default to encoding as RFC3339 timestamps. Including the
// "unix" option signals that the field should be encoded as a Unix time (see
// time.Unix())
//
// Slice and Array values default to encoding as multiple URL values of the
// same name. Including the "comma" option signals that the field should be
// encoded as a single comma-delimited value. Including the "space" option
// similarly encodes the value as a single space-delimited string. Including
// the "semicolon" option will encode the value as a semicolon-delimited string.
// Including the "brackets" option signals that the multiple URL values should
// have "[]" appended to the value name. "numbered" will append a number to
// the end of each incidence of the value name, example:
// name0=value0&name1=value1, etc.
//
