pip install zyte-api-convertor

Usage

    Usage: zyte-api-convertor <payload> --project-name <project_name> --spider-name <spider_name>
    Example: zyte-api-convertor '{"url": "https://httpbin.org/ip", "browserHtml": true, "screenshot": true}' --project-name sample_project --spider-name sample_spider

    Usage: zyte-api-convertor <payload> --project-name <project_name>
    Example: zyte-api-convertor '{"url": "https://httpbin.org/ip", "browserHtml": true, "screenshot": true}' --project-name sample_project

    Usage: zyte-api-convertor <payload> --spider-name <spider_name>

Example

zyte-api-convertor expects a valid json payload at the least. But it does have other options as well. You can use the --project-name and --spider-name options to set the project and spider name. If you don't use these options, it will use the default project and spider name.

zyte-api-convertor '{"url": "https://httpbin.org/ip", "browserHtml": true, "screenshot": true}' --project-name sample_project --spider-name sample_spider

Output:

mukthy@Mukthys-MacBook-Pro % zyte-api-convertor '{"url": "https://httpbin.org/ip", "browserHtml": true, "screenshot": true}' --project-name sample_project --spider-name sample_spider

Sample Spider Code:

import scrapy


class SampleQuotesSpider(scrapy.Spider):
    name = "sample_spider"

    custom_settings = {
        "DOWNLOAD_HANDLERS": {
            "http": "scrapy_zyte_api.ScrapyZyteAPIDownloadHandler",
            "https": "scrapy_zyte_api.ScrapyZyteAPIDownloadHandler",
        },
        "DOWNLOADER_MIDDLEWARES": {
            "scrapy_zyte_api.ScrapyZyteAPIDownloaderMiddleware": 1000
        },
        "REQUEST_FINGERPRINTER_CLASS": "scrapy_zyte_api.ScrapyZyteAPIRequestFingerprinter",
        "TWISTED_REACTOR": "twisted.internet.asyncioreactor.AsyncioSelectorReactor",
        "ZYTE_API_KEY": "YOUR_API_KEY",
    }

    def start_requests(self):
        yield scrapy.Request(
            url="https://httpbin.org/ip",
            meta={
                "zyte_api": {
                    "javascript": False,
                    "screenshot": True,
                    "browserHtml": True,
                    "actions": [],
                    "requestHeaders": {},
                    "geolocation": "US",
                    "experimental": {"responseCookies": False},
                }
            },
        )

    def parse(self, response):
        print(response.text)

Please note that the ZYTE_API_KEY is not set in the custom_settings of the spider. You need to set it before running it.
