This tutorial will also continue the same example. Some of the important test verification are. This tutorial will cover the following verification for Response Status :.
IResponse is an interface which has lots of properties, mostly which can help to get parts of the received response. Look at some of the important properties. A simple response followed by a dot restResponse would show the available properties on the response object. As shown in the image below. This property returns an HttpStatusCode which is an Enum.
Try running the test and notice that the test will pass. This is because the web service indeed returns a status code of If the Request is successful, Status Code is returned otherwise Status Code other than will be returned. At this moment do not change the status code. The code looks as shown below. Now run your test class and check the result. The reason is that the web service returns an error code of when invalid city name is sent to it.

The Ultimate RestSharp Client in ASP.NET and C#
I'm using RestSharp to make calls to a webservice. All is well but I was wondering if it would be possible to print the raw request headers and body that is sent out and the raw response headers and the response body that comes back.
As we already know RestSharp doesn't provide a mechanism to achieve exactly what you want and activating the. Net tracing is a bit overkilling IMO.
For logging debugging purposes something that I can leave turned on for a while in PROD for example I have found this approach to be very useful although it has some details on how to call it, read below the code :. I found this tip here. You have to loop through the request. Parameters list and format it to a string in whatever format you like. If you want the output to show request headers and then the body similar to Fiddler, you just need to order the collection by Request headers and then by Request body.
The Parameter object in the collection has a Type parameter enum. Execute or RestClient. The Authenticate method is passed the RestRequest currently being executed giving you access to every part of the request data headers, parameters, etc.

But you might be better off with a "sniffing" proxy as suggested above. I want to do this everytime in my.Our latest project is very large, and uses lots of different APIs, and so we needed a way to create many different client classes that could consume many different APIs but still use common features like caching and error logging.
Said base class will need to implement common functionality e.
Come along with me as I condense a week's worth of research and coding into one word blog post and build the Ultimate RestSharp Client! The ultimate RestSharp client that we're going to build needs to support the following scenarios:. Before we build our ultimate RestSharp client, let's first define the three items which need to be injected into said client. The cache service we used in an earlier post will serve us well now.
NET as its default serializer see this readme. So, we must inject a serializer into our ultimate client, which will use JSON. NET anyway because that's what I like. I stole the following class from this fantastic blog post and it's worked pretty well for us. This is the simplest of the three injection prerequisites. You will want to replace this implementation with one of your own design. Here's a very basic error logger interface and class:.
With all three prerequisite items in place, we can now start to code our ultimate RestSharp client! In order to build our ultimate RestSharp client, we'll first need a class that inherits from RestSharp's RestClient class:. We also need a constructor to inject our three prerequisite classes into this client, as well as a base URL for which each child client will be using for their APIs.
Such a constructor looks like this:. Note that we are using JSON for this ultimate client. You can use other formats e. Once we've got the constructor build, it's time to start coding the guts of our ultimate client, starting with We have two different kinds of error logging in this system: the generic error logging and the more specific Timeout checks. We implemented timeout checks in an earlier postgo check that out if you want more details.
For now, here's some code to accomplish each of these. Once we've got the error logging in place, we can now discuss the kinds of operations we want this client to be able to perform.Finally, you'll see how to work with C objects. If you prefer to follow along with the final sample for this topic, you can download it. For download instructions, see Samples and Tutorials. NET core. You can find the installation instructions on the. NET Core Downloads page. The descriptions below use Visual Studio Codewhich is an open source, cross platform editor.
However, you can use whatever tools you are comfortable with. The first step is to create a new application. Open a command prompt and create a new directory for your application.
Make that the current directory. Enter the following command in a console window:. This creates the starter files for a basic "Hello World" application.
The project name is "WebApiClient". As this is a new project, none of the dependencies are in place. The first run will download the.
NET Core framework, install a development certificate, and run the NuGet package manager to restore missing dependencies. Before you start making modifications, type dotnet run see note at the command prompt to run your application. It also performs dotnet build if your application needs to be rebuilt. After your initial setup, you will only need to run dotnet restore or dotnet build when it makes sense for your project. One of the key design goals for.
NET Core is to minimize the size of the.Or, you can follow the standard RFC that including request method, headers, and body. If you'd like to use the full power of searching, selecting or manipulating in Visual Studio Code, you can also preview response in an untitled document by setting rest-client. Once a request is issued, the waiting spin icon will be displayed in the status bar until the response is received. You can click the spin icon to cancel the request.
After that, the icon will be replaced with the total duration and response size. You can view the breakdown of the response time when hovering over the total duration in status bar, you could view the duration details of SocketDNSTCPFirst Byte and Download.
When hovering over the response size in status bar, you could view the breakdown response size details of headers and body. Send Request link above each request will only be visible when the request file is in http mode, more details can be found in http language section.
You may even want to save numerous requests in the same file and execute any of them as you wish easily. REST Client extension could recognize requests separated by lines begin with three or more consecutive as a delimiter.
Place the cursor anywhere between the delimiters, issuing the request as above, and the underlying request will be sent out. REST Client extension also provides the flexibility that you can send the request with your selected text in editor. The first non-empty line of the selection or document if nothing is selected is the Request Line. Below are some examples of Request Line :. If request method is omitted, request will be treated as GETso above requests are the same after parsing.
Sometimes there may be several query parameters in a single request, putting all the query parameters in Request Line is difficult to read and modify. So we allow you to spread query parameters into multiple lines one line one query parameterwe will parse the lines in immediately after the Request Line which starts with? The lines immediately after the request line to first empty line are parsed as Request Headers.
Please provide headers with the standard field-name: field-value format, each line represents one header. You can also change the default value in setting rest-client. Below are examples of Request Headers :. If you want to provide the request body, please add a blank line after the request headers like the POST example in usage, and all content after it will be treated as Request Body.
Below are examples of Request Body :. Besides that you can also author GraphQL variables in the request body. GraphQL variables part in request body is optional, you also need to add a blank line between GraphQL query and variables if you need it.
The following code illustrates this:. The issuing request command is the same as raw HTTP one. REST Client will automatically parse the request with specified parser. Supported options are listed below:. Each time we sent an http request, the request details method, url, headers, and body would be persisted into file. After specified request history item is selected, the request details would be displayed in a temp file, you can view the request details or follow previous step to trigger the request again.
In the upper right corner of the response preview tab, we add a new icon to save the latest response to local file system. After you click the Save Full Response icon, it will prompt the window with the saved response file path. You can click the Open button to open the saved response file in current workspace or click Copy Path to copy the saved response path to clipboard.
Another icon in the upper right corner of the response preview tab is the Save Response Body button, it will only save the response body ONLY to local file system.
You can also overwrite the MIME type and extension mapping according to your requirement with the rest-client.We will continue with the same example in those tutorials and verify the body if the Response.
If you have not gone through the first two tutorials then I would suggest you go through these links. Let us continue with the example of Weather web service that we used in the previous tutorials. When we request for the Weather details of a particular city, Server responds by sending the Weather details of the city as the Response Body. Response interface contains property called content to get the response body. The response body which we receive is basically in JSON format, which contain variable name and its value as shown below.
ResponseBody can return the response body in a String format. We can use simple String methods to verify certain basic level of values in the Response. For e. The below code shows how to check for sub string presence.
We can also ignore the casing using the String internal methods. To do this we will convert the Response in lower case and then compare it with our lower case string value. Below code demonstrates that. This is not a fool proof way of testing a particular node in the Response. There are better ways, Response interface gives you a mechanism to extract nodes based on a given Json using Jobject.
There is a method calledJObject. Parse restResponse. Contentwhich returns an element-node Newtonsoft. This object can be used to further query specific parts of the Response Json.
Let us continue with the above example and retrieve the City from the Response. To do so, we will simply get the JObject object from the Response interface and then query for the particular node. Just to be very clear, let us look at the Weather API response again. Try it out on the JObject Evaluator to verify the output.The REST client examples I share here are based on the examples on the HttpClient website; I've mostly just tried to make them a little easier to read, and add some additional documentation to them.
That service actually returns information in an RSS format, but if you don't mind parsing that XML, it's an easy way to get weather updates. It also shows how to get all of the headers from the web service you're calling. Hopefully you can try this against different URLs where you can examine the header information in more detail.
As you can see in this next example, this class is based on the Apache HttpClient ClientConnectionRelease example class, though I've added quite a bit of processing ability to this class. Here's the source code:. I've tried to document all of these classes fairly well, so I won't discuss them much here. This is easier when you're just calling one web service from one host, while the earlier approach may be better if you're calling many web services from one host, such as from the Twitter API.
As you can see, this makes the code much easier to digest. As mentioned, these examples are heavily based on the Apache HttpClient samples, and I recommend looking at that code for more examples.
