Drawing QR Code In Java
Using Barcode creator for Java Control to generate, create Quick Response Code image in Java applications.
To handle both of the test cases, the response code must be checked If it is 200, you parse the response body and return it If the response code is 404, the library should return a nil Finally, if some other response is encountered, you raise an exception

Ruby HTTP Libraries
Barcode Decoder In Java
Using Barcode decoder for Java Control to read, scan read, scan image in Java applications.
There are many different libraries in Ruby for making HTTP calls A more detailed discussion of these options appears in 6, Connecting to Services However, it s worth noting that installing Typhoeus may take a little more effort For this reason, this example uses only the basic HTTP functionality in the library This should make it an easy adjustment to use Net::HTTP, HTTParty, Patron, Curb, or any other library
QR Code Generator In C#

Creating a User
QR Code Creation In .NET
Using Barcode generation for ASP.NET Control to generate, create QR Code image in ASP.NET applications.
The next step in wiring up the service functionality is to enable the client library to create a user

Using Barcode generator for .NET Control to generate, create QR-Code image in .NET framework applications.
In the client_specrb file, you add the following it block right after the user not found test:
EAN / UCC - 13 Generation In Java
Using Barcode drawer for Java Control to generate, create USS-128 image in Java applications.
it "should create a user" do user = Usercreate({ :name => "trotter", :email => "no spam", :password => "whatev"}) user["name"]should == "trotter" user["email"]should == "no spam" Userfind_by_name("trotter")should == user end

Generate GS1 - 12 In Java
Using Barcode maker for Java Control to generate, create GTIN - 12 image in Java applications.
This user creation test actually checks for two things First, it confirms that when a call is made to Usercreate, the test returns the user hash Then the final line confirms that the user was actually created in the service Notice that the previously implemented find_by_name functionality is in use The call verifies that the server understands the create call the client sent, and it ensures that there is end-to-end coverage with the client and service

Implementing Usercreate
ECC200 Encoder In Java
Using Barcode maker for Java Control to generate, create ECC200 image in Java applications.
Now you can wire up user creation After the find_by_name method, you add the following code:
UPC-E Maker In Java
Using Barcode generator for Java Control to generate, create UPC E image in Java applications.
def selfcreate(attributes) response = Typhoeus::Requestpost( "#{base_uri}/api/v1/users", :body => attributesto_json) if responsecode == 200 JSONparse(responsebody) else raise responsebody end end
GS1 - 12 Printer In .NET Framework
Using Barcode drawer for .NET framework Control to generate, create Universal Product Code version A image in .NET applications.
The implementation is very simple The attributes are passed in as a hash A POST is made to the service, with the attribute s hash serialized as JSON in the body This is slightly different from a regular POST request because it doesn t use form variables The service expects a JSON hash in the body Notice that no validation occurs in the client library The server is able to perform that validation and return errors This example handles only successful responses gracefully In a more fully featured client library, the errors should also be handled Because create user is running against a locally running service, the first time the spec is run, the user is created Remember that the service startup clears out the test database This means that between each full run of the client specs, the local test service needs to be restarted 7, Developing Service Client Libraries, explores other methods for client library testing
Creating Barcode In Visual Studio .NET

Spec ing Userupdate
Data Matrix 2d Barcode Creation In C#.NET
Using Barcode creation for Visual Studio .NET Control to generate, create Data Matrix 2d barcode image in VS .NET applications.
The user update test looks very similar to the user creation test You add the following code after the create user test:

it "should update a user" do user = Userupdate("paul", {:bio => "rubyist and author"}) user["name"]should == "paul" user["bio"]should == "rubyist and author" Userfind_by_name("paul")should == user End
The test verifies that the user model has a class method called update It takes the user name as the first argument and the attribute s hash as the second Further, this method should return the full user attribute s hash Finally, the test verifies that the user has actually been updated
Implementing Userupdate
With the spec written, the update user method can be added to clientrb After the create method, you add the following code:
def selfupdate(name, attributes) response = Typhoeus::Requestput( "#{base_uri}/api/v1/users/#{name}", :body => attributesto_json) if responsecode == 200 JSONparse(responsebody) else raise reponsebody end end
Here, an HTTP PUT request is made to the service to update the specific resource of the user with the passed-in name Just as with user creation, the JSON serialized attribute s hash is passed in the request body It should be noted that a PUT with this service works as it does in Rails That is, the attributes that are in the hash are updated, while the omitted attributes remain the same The service should be restarted between each run of the client specs
