Understanding the difference between HTTP requests with Riccio and QT
In making HTTP requests, developers have several tools available. Two popular options come from the commander Curl and QT (also known as Qwebengine) for the development of the network. In this article, we will see why you could experience a “bad http request” with “QT, but a successful request with" curl ".
Problem qt
QT is a powerful frame that allows developers to create high -performance network applications with a qt network engine. Although it is an excellent choice for the construction of complex network applications, it may have some restrictions to make simple HTTP requests.
Here are some reasons why you could try questionsqt:
* Non -integrated HTTP customer : Unlike theCurl ‘, a HTTP customer fully equipped, with QT, there is no integrated customer. This means that it is necessary to use the Javascript interface for the QT Webengine engine, which can be difficult.
* Processing of limited errors : although it is to provide good processing of errors, it is not solid as’ curl. If the error occurs when making a request, it is not possible to receive the same control of the curl '.
* No cache or continuous responses : By default, QT does not allow you to store in the cache or continue the answers, which can lead to problems while working with large information troops or frequently used resources.
Care news: using curls for http requests
Now let's talk about why you make simple http requests with the curl 'app is a better choice. Here are some reasons why:
* The integrated HTTP customer : "CURL" offers a completely present HTTP customer that offers solid management of the errors and features of the cache.
* Easy -to -use
:CURL 'is a simple syntax, so it is easy to work with HTTP requests also for beginners.
* Flexibility : You can use a variety of options such as securities, query parameters and file download using the "curl" application, which is useful while working with complex http requests.
Example of use: HTTP Curly request
Here is an example of how you can make a simple http request for a bin with the "curl" app:
Bash
API Key Key Set
Api_Key = “Vmpuze6mv9sd5vnk4hlwfsor6Ake2ZVSW0Mumigwcipy6uco14y7Ju91deh8a”
Make a request I can for bees binance
Curl -x Mail \
‘ \
-H “type of content: application/json” \
-H “X-Mamb-Epikey: $ Api_key”
`
In this example, we request a simple request to find the current Bitcoin price in Binance. We have also set the application key to the application and use the names of the right securities for the "CURL" command.
Conclusion
Although QT offers useful features in web development, its HTTP client is not solid as "curl". For simple requests http,Curlis a better choice thanks to its ease of use, flexibility and processing of integrated errors. In this article, we explored because you could try questions with "QT, but we asked a successful request with the” Curl` “app. your network!
