fetch api response object code example

Example 1: javascript fetch api

fetch('http://example.com/movies.json')
  .then((response) => {
    return response.json();
  })
  .then((data) => {
    console.log(data);
  });

Example 2: js fetch api

// Example POST method implementation:
async function postData(url = '', data = {}) {
  // Default options are marked with *
  const response = await fetch(url, {
    method: 'POST', // *GET, POST, PUT, DELETE, etc.
    mode: 'cors', // no-cors, *cors, same-origin
    cache: 'no-cache', // *default, no-cache, reload, force-cache, only-if-cached
    credentials: 'same-origin', // include, *same-origin, omit
    headers: {
      'Content-Type': 'application/json'
      // 'Content-Type': 'application/x-www-form-urlencoded',
    },
    redirect: 'follow', // manual, *follow, error
    referrerPolicy: 'no-referrer', // no-referrer, *no-referrer-when-downgrade, origin, origin-when-cross-origin, same-origin, strict-origin, strict-origin-when-cross-origin, unsafe-url
    body: JSON.stringify(data) // body data type must match "Content-Type" header
  });
  return response.json(); // parses JSON response into native JavaScript objects
}

postData('https://example.com/answer', { answer: 42 })
  .then(data => {
    console.log(data); // JSON data parsed by `data.json()` call
  });

Example 3: api response

Response 
				
				 Status code 
				 			2xx -->>  success 
				 			4xx -->>  client side error
				 			5xx -->>  server side error 
				 Header 
				 		meta data about your response 
				 		like Content-Type, Date and some other info

				 Body | Payload		
				 		The response we got from the server 
				 		and this where we do lots of validation

Example 4: response body api

Basicall we are checking response body
to verify if request matches with response.
In the response we are verifying
(body, status code, header, response time,
 test structure of json against the given jsonSchema)
 
 
If file not under resources: 
File schemaFile = new File("src/test/resources/postSuccessResponseSchema.json");

     given()
        .spec(adminReqSpec)
        .contentType(ContentType.JSON)
        .body(abcUtil.getRandomHeroPOJO_Payload()).
     when()
        .post("/HEROS").
     then()
        .body(matchesJsonSchema( schemaFile )  ) 
        
        
If schema file under resources:
  given()
      .spec(adminReqSpec)
      .queryParam("nameContains","a")
      .queryParam("gender","Female").
  when()
      .get("/abc/search").
 then()
 	  .time( lessThan(2000L));	
      .body(matchesJsonSchemaInClasspath("searchSpartanSchema.json") )
