Moya is more capable of simulating data debugging than Android Retrofit.
Currently, most apps use JSON as the Message Protocol. for Android development, we generally use Gson for parsing. In Swift development, after comparing ObjectMapper, Argo + Curry, and SwiftyJson, we decided to use ObjectMapper as the JSON parsing framework. ObjectMapper supports the following features:

think this method is similar to the case where the member function unHtmlEntities () in the HtmlUtils class in C ++ is static, so that you can directly use "class name :: the member function name (HtmlUtils: unHtmlEntities () is called.
This indicates that the message is sent from the View to HtmlUtils. (one-way transmission), and the message can also be sent in two directions.

Since the beginning of the 1990 's, HTML has been invented in various forms, with different browsers incorporating their own style language, which readers can use to adjust how the page is displayed. The first style sheet is intended for the reader, and the initial HTML version contains only a few display attributes, and the reader determines how the page should be displayed.
However, with the growth of HTML, in order to meet the designer's requirements, HTML has a lot of display functions. Wi

Class Debug {
Function display (){
Echo ($ this-> errorMsg );
}
}
Class SomeClass {
Var $ errorMsg = 'This is an error message ';
Function someFunction (){
If (DEBUG = 1 ){
Debug: display ();
}
}
}
Define ('debug', 1 );
$ SomeClass = new SomeClass;
$ SomeClass-> someFunction ();
?>
[Output information: "This is an error message"]
Here, SomeClass sends a message to Debug. Debug accesses the $ errorMsg attribute of SomeClass.

protocol login. Many browsers support other types of URLs and protocols, such as ftp: FTP (File Transfer Protocol), Gopher: Gopher and https: HTTPS (SSL-encrypted HTTP).
Early Web browsers only support simple versions of HTML. The rapid development of software-specific browsers leads to non-standard HTML code generation. However, with the growth of HTML, in order to meet the designer's requirements, HTML has a lot of display functions. With the addition of these features the foreign-defined sty
