Getting this error when scraping JSON with scrapy: Spider must return request, item, or None, got &#-CodePudding

I am trying to get a json field with key "longName" with scrapy but I am receiving the error: "Spider must return request, item, or None, got 'str'".

The JSON I'm trying to scrape looks something like this:

{
   "id":5355,
   "code":9594,

}sadsadsd

This is my code:

import scrapy
import json

class NotesSpider(scrapy.Spider):
    name = 'notes'
    allowed_domains = ['blahblahblah.com']
    start_urls = ['https://blahblahblah.com/api/123']

    def parse(self, response):
        data = json.loads(response.body)
        yield from data['longName']

I get the above error when I run "scrapy crawl notes" in prompt. Anyone can point me in the right direction?

CodePudding user response：

If you only want longName modifying your parse method like this should do the trick:

    def parse(self, response):
        data = json.loads(response.body)
        yield {"longName": data["longName"]}
