Description
ZennoPoster allows using HTTP requests when working with different websites. You can receive data with GET requests, for example, request search results by request in a search engine, download files, parse data, work with API of web services and applications. Performing actions without a browser can significantly reduce the load on computer resources.

As a file
This mode is worth choosing if you are trying to download a file using a request.
The path to the downloaded file will be saved to the variable.
By default, files are downloaded to the Trash folder in the ZennoPoster installed directory. The path to it may look like this - C: \ Program Files \ ZennoLab \ RU \ ZennoPoster Pro V7 \ 7.4.0.0 \ Progs \ Trash \ googlelogo_color_92x30dp.png
You can change this path in the settings, globally for all projects. Or by using an action during template execution.
As file + headers
The variable will save the response headers and the path to the downloaded file.
Put in variable
Here you need to select (or create a new) variable into which the query result will be saved.

CookieContainer - Starting from version 5.18.0.0 in the additional settings in the section “Headers: User settings” there is an option “Use CookieContainer” . CookieContainer allows GET / POST requests to share cookies with the browser, i.e. if they are changed as a result of the request, then in the browser they will also change and vice versa. This allows you to easily transfer part of the logic of working with the site to POST / GET requests.

Format: name = value, several are separated by; (semicolon). Example:
user=1992103;session=f79fcadd847b80f9df78ba4fb276c867;id=889
Starting from version 7.1.6.0 (5.45.0.0) this input field is displayed only if the Use CookieContainer setting is disabled (described below).
Use Cookie Container
Cookie Container allows you to synchronize cookies both with the browser and between individual requests, without the need for manual parsing and substitution.

The project works with the site using requests, but you need to be authorized to work. Let's imagine that the authorization process is very complicated, so that it can be repeated on requests, therefore, to enter the site, we use the browser mode. Then we turn off the browser and start working with the site using requests. By enabling the Use Cookie Container setting, cookies will be automatically synchronized between the browser and requests, you do not need to do anything manually - cookies will be substituted automatically. |
Example of Custom Settings
Using profile variables for headers and manual cookie substitution.

Do not use a browser
If you are not using the browser when working with work exclusively with the help of requests, you must disable it in the Project Settings then you can turn off the browser, thereby saving computer resources; you can do this either in the project settings or using the Browser Settings action.
...
...
HTTP-Request transfer method
For more information on how to transfer HTTP requests, see Project Settings .
...
Usage example
You need to go to the page and collect all the values for the specified conditions. Since the site gives all the values without using a browser, we turn it off.
...
Turn off the browser.
Add a GET request action.
Configuring.
We receive the response of the request into a variable.
We are looking for the necessary values
Thus, disabling the browser will significantly save computer resources. The difference in the number of threads between working with tabs and queries can be more than significant.
...
ZennoPoster has two methods of working with requests - third-party development (standard method, Chilkat library) and our own (alternative method). If something does not work for you when working with HTTP requests using the standard method, then try switching to an alternative method.
You can change the method of sending requests in the program settings (globally for all projects) or in the settings of a specific project.
...
Usage example
Find out the current ip address from which the project is running.
To do this, just make a GET request at https://api.ipify.org/, and in the Proxy tab, select the Current proxy of the project.
