QT Programming QT-based Dictionary development series < Seven >--call network API

In the previous article we implemented the local thesaurus design, can complete the local search word function, then this article mainly talk about how to call the network API to implement the dictionary network search Word function .

selection of dictionary APIs

Basically on the market do dictionary software companies have corresponding APIs, such as Youdao, Jinshan and so on, but generally need API key, a little trouble, so I found a simple and easy to use scallop net api:http://www.shanbay.com/help/ developer/api/oddly enough, the API says it's going to be deactivated, and it can be done from the time I finished the software last summer, and now it works.

use of the Scallop dictionary API

To get to the API address of the scallop web I gave above, we can see that the API documentation is still more detailed. As I have never been in contact with the network programming people, can also be more understanding. Let's briefly talk about how to use these APIs. Since the function of my dictionary is only to look up words and add words, it is only necessary to use the corresponding API interface in the document.

At the beginning of the API introduction, there are the following text:

Therefore, when using this API, we must first register ! After registering and logging in, we continue to look at the API documentation, as we only implement the ability to query and save words (and, of course, other features in the document, using similar methods), so just focus on the following:

It is possible that you have seen the contents of the picture, or confused, then we can try it first. First make sure you are logged in to the scallop mesh and then enter it in the browser : Http://www.shanbay.com/api/word/test, and then we can see the following:

The content in the graph is the result of our query for the test word. If we want to save the word, we just need to enter it in the browser: http://www.shanbay.com/api/learning/add/test we get the following results:

It means that the word has been saved by us and given a number. Therefore, when we query the word again, in the browser input: Http://www.shanbay.com/api/word/test will find that the ID is no longer 0, but the same number as above:

So far, none of the above-mentioned operations involve programming, which is done directly in the browser. However, we want to implement this function in the dictionary, we have to face two problems: 1, programming to implement the user's login and call Api;2, parse the call API after the return of the JSON-formatted data.

These two issues will be resolved in the following series of articles, please pay attention to.
