[SalesForce] Rest api HttpGet issue

I have created a class for api request. I am also sending a parameter in url while requesting for HttpGet. How can I get the value from the url in a HttpGet method. When I added the RestRequest req, RestResponse res as parameter to my apex method I am getting an error

Error: Compile Error: Invalid type: HTTP GET/DELETE methods do not support parameters at line 4 column 26

Can anyone help me out on this issue. This is my apex class.

@RestResource(urlMapping='/mycall')
global class mycallclass{
  @HttpGet
  global static String getmycall(RestRequest req, RestResponse res) {
    String name = RestRequest.params.get('name');
    return 'WooW Success';
  }
}

Best Answer

You can access the params map via static fields like this:

Map<String, String> params = RestContext.request.params;
String name = params.get('name');

(Remove the getmycall method parameters you presently have in your code.)

I have solved the issue. Solution: If you have namespace defined in salesforce you need to define it with /services/apexrest/namespace/lead

You need to use make use of the RestContext.request. The way you do so will vary based on the Http method in question.

POST

Here you will need to parse the RestContext.request.requestBody. Usually this will be a JSON payload which you deserialize. For example:

public class PostPayload
{
    public String firstName;
    public String lastName;
    public String etc;
}

@HttpPost
global static void String createLead()
{
    String jsonInstance = RestContext.request.requestBody.toString();
    PostPayload payload = JSON.deserialize(jsonInstance), PostPayload.class);
    // do stuff
}

This payload can be set in your tests as follows:

MyRestService.PostPayload payload = new MyRestService.PostPayload;
payload.firstName = 'Road';
payload.lastName = 'Runner';
RestContext.request.requestBody = Blob.valueOf(JSON.serialize(payload));

GET

Here you will need to pull values out of RestContext.request.params. I tend to make my keys constants so that I can test against them more easily.

public static final String SAP_ID_PARAM = 'sapId';

@HttpGet
global static void String getLead()
{
    Id sapId = RestContext.request.params.get(SAP_ID_PARAM);
    if (String.isBlank(sapId))
    {

    }
    // do stuff
}

This value can be set in your tests as follows:

RestContext.request.params.put(MyRestService.SAP_ID_PARAM, 'Some Value');
