A SmartFile Open Source project. Read more about how SmartFile uses and contributes to Open Source software.

Summary

This library includes two API clients. Each one represents one of the supported authentication methods. SFBasicClient is used for HTTP Basic authentication, using an API key and password. SFOAuth1Client is used for OAuth (version 1) authentication, using tokens, which will require user interaction to complete authentication with the API.

Both clients provide a wrapper around AFNetworking library, taking care of some of the mundane details for you. The intended use of this library is to refer to the API documentation to discover the API endpoint you wish to call, then use the client library to invoke this call.

SmartFile API information is available at the SmartFile developer site.

Installation

Get the source code from GitHub.

$ git clone https://github.com/smartfile/client-objectivec.git smartfile
$ cd smartfile

You can see following directory structure.

Example
SmartFile
SmartFileTests
README.rst

Copy SmartFile folder to your project. In your source code import

#import "SFBasicClient.h"

or

#import "SFOAuth1Client.h"

depending on which authentication method you want to use.

More information is available at GitHub.

Usage

Choose between Basic and OAuth authentication methods, then continue to use the SmartFile API. Check the Example project which implements a simple SmartFile browser or SmartFileTests project that has dosen of SmartFile API call examples.

Running Example

Before running Example application ensure that SM_API_URL and SM_API_VERSION are set to appropriate values in SFCredentials.h. Otherwise the exception will be raised.

Running Tests

Before running tests ensure that SM_API_URL and SM_API_VERSION as well as SM_BASIC_API_KEY SM_BASIC_API_PASSWORD are set in Credentials.h. Otherwise tests will fail.

Basic Authentication

Basic authentication is quite simple and requires you to provide API key and password.

#define SM_API_URL      @"https://your_user_name.smartfile.com/"
#define SM_API_VERSION  @"2"

#define SM_BASIC_API_KEY        @"your_basic_api_key"
#define SM_BASIC_API_PASSWORD   @"your_basic_api_password"

NSError *error = nil;

SFBasicClient *basicClient = [[SFBasicClient alloc] initWithUrl:SM_API_URL version:SM_API_VERSION];

error = [basicClient setKey:SM_BASIC_API_KEY];

if (error != nil) {
    // Key format is invalid.
}

error = [basicClient setPassword:SM_BASIC_API_PASSWORD];

if (error != nil) {
    // Password format is invalid.
}

[basicClient doGetRequest:@"/ping" 
                   object:nil
                    query:nil
                 callback:^(NSData *data, NSInteger statusCode, NSError *error)
{
    if (error != nil) {
        // Invalid credentials.
    } else {
        // Login successful.
    }
}];

OAuth Authentication

Authentication using OAuth authentication is bit more complicated, as it involves tokens and secrets.

#define SM_API_URL      @"https://your_user_name.smartfile.com/"
#define SM_API_VERSION  @"2"

#define SM_OAUTH_TOKEN  @"your_oauth_token"
#define SM_OAUTH_SECRET @"your_oauth_secret"

NSError *error = nil;

SFOAuth1Client *oauthClient = [[SFOAuth1Client alloc] initWithUrl:SM_API_URL version:SM_API_VERSION];

error = [oauthClient authorizeWithToken:SM_OAUTH_TOKEN secret:SM_OAUTH_SECRET callback:^(NSError *error) {
    // AFOAuth1Client performs authorization. Web view will be opened automatically if needed.
    if (error != nil) {
        // Authorization failed.
    } else {
        // Authorization successful.
    }
}];

if (error != nil) {
    // OAuth token/secret format is invalid.
}

Calling endpoints

Once you instantiate a client, you can use the get/put/post/delete methods to make the corresponding HTTP requests to the API. There is also a shortcut for using the GET method, which is to simply invoke the client.

SFBasicClient *basicClient = [[SFBasicClient alloc] initWithUrl:SM_API_URL version:SM_API_VERSION];

[basicClient setKey:SM_BASIC_API_KEY];
[basicClient setPassword:SM_BASIC_API_PASSWORD];

[basicClient doGetRequest:@"/ping"
                   object:nil
                    query:nil
                 callback:^(NSData *data, NSInteger statusCode, NSError *error)
{
    // Do something with response.
}];

Some endpoints accept an ID, this might be a numeric value, a path, or name, depending on the object type. For example, a user's id is their unique username. For a file path, the id is it's full path.

SFBasicClient *basicClient = [[SFBasicClient alloc] initWithUrl:SM_API_URL version:SM_API_VERSION];

[basicClient setKey:SM_BASIC_API_KEY];
[basicClient setPassword:SM_BASIC_API_PASSWORD];

[basicClient doGetRequest:@"/path/info/"
                   object:nil
                    query:nil
                 callback:^(NSData *data, NSInteger statusCode, NSError *error)
{
    // Do something with response.
}];

Result will be similar to:

{u'acl': {u'list': True, u'read': True, u'remove': True, u'write': True},
 u'attributes': {},
 u'extension': u'',
 u'id': 7,
 u'isdir': True,
 u'isfile': False,
 u'items': 348,
 u'mime': u'application/x-directory',
 u'name': u'',
 u'owner': None,
 u'path': u'/',
 u'size': 220429838,
 u'tags': [],
 u'time': u'2013-02-23T22:49:30',
 u'url': u'http://localhost:8000/path/info/'}

File transfers

Uploading and downloading files is supported.

To upload files, pass array of file paths in local filesystem.

SFBasicClient *basicClient = [[SFBasicClient alloc] initWithUrl:SM_API_URL version:SM_API_VERSION];

[basicClient setKey:SM_BASIC_API_KEY];
[basicClient setPassword:SM_BASIC_API_PASSWORD];

NSString *testFilePath = [[NSBundle bundleForClass:[self class]] pathForResource:@"test_file" ofType:@"txt"];

[basicClient doPostRequest:@"/path/data/"
                   object:nil
                    query:nil
                    files:@[testFilePath]
                 callback:^(NSData *data, NSInteger statusCode, NSError *error)
{
    // Do something with response.
}];

Downloading:

SFBasicClient *basicClient = [[SFBasicClient alloc] initWithUrl:SM_API_URL version:SM_API_VERSION];

[basicClient setKey:SM_BASIC_API_KEY];
[basicClient setPassword:SM_BASIC_API_PASSWORD];

NSString *outPath = [@"~/test_file.txt" stringByExpandingTildeInPath];

[basicClient doGetRequest:@"/path/data"
                   object:@"/test_file.txt"
                    query:nil
               outputFile:outPath
                 callback:^(NSData *data, NSInteger statusCode, NSError *error)
{
    // Do something with response.
}];

Tasks

Operations are long-running jobs that are not executed within the time frame of an API call. For such operations, a task is created, and the API can be used to poll the status of the task.

SFBasicClient *basicClient = [[SFBasicClient alloc] initWithUrl:SM_API_URL version:SM_API_VERSION];

[basicClient setKey:SM_BASIC_API_KEY];
[basicClient setPassword:SM_BASIC_API_PASSWORD];

NSString *testFilePath = [[NSBundle bundleForClass:[self class]] pathForResource:@"foobar" ofType:@"png"];

[basicClient doPostRequest:@"/path/data/"
                   object:nil
                    query:nil
                    files:@[testFilePath]
                 callback:^(NSData *data, NSInteger statusCode, NSError *error)
{
    // Do something with response.
}];

[basicClient doGetRequest:@"/task"
                   object:@"uuid"
                    query:nil
               outputFile:outPath
                 callback:^(NSData *data, NSInteger statusCode, NSError *error)
{
    // Check status.
}];
