When working with API, you often need to convey data structures as functional arguments. However, some application subscriptions, including exports, require the structure of feed parameters with a specific syntax. In this article, we examine how to skip the structures and double into the Viem "args" field.
Understanding API Viem
Before immersing in details, some basic things are quickly discussed by the subscription of the application Viem:
Viem is an open source media management system, which provides various application interfaces for interaction with its services.
The "Encodefunctiondata" function is waiting for a specific syntax when it comes to it. In this article, we focus on this syntax.
If you want to ignore structures or dumplings as arguments, you must use the "args" field.
"Encodefunctiondata" as
The "Encodefunctiondata" synthesis is used to send data structures as functional arguments. The basic structure of the argument is:
Json
{
"Type": ,
"Value":
}
Where:
defines the type of value (eg" Struct "," Krotka ").
indicates that the value can be any type.
Skiping Structures Encodefunctiondata
To convey the structure as an argument, you must create an object with two features: «type» and «value».
`Json
{
"Type": "Struct",
"Value": {
"Name": "Mystruct",
"Pola": [
{"Name": "Field1", "Type": "String"},
{"Name": "Field2", "Type": "Integer"}
-
}
}
In this example, the «Encodefunctiondata» function is waiting for an object with one field called «».
shorts to Encodefunctiondata
To convey as an argument, you can create a set of objects where each object has the required fields:
`Json
{
"Type": "Krotka",
"Value": [
{
"Name": "field 1",
"Type": "String"
},
{
"Name": "Field2",
"Type": "Integer"
}
-
}
Infanting Everything
To use the «Encodefunctiondata» function with a structure or short, you need to create an object that matches its structure. Here is an example:
`Json
Const Struct = {
Type: "structure",
Value: {
Name: "mystruct",
Pola: [
{Name: "Field1", type: "String"},
{Name: "Field2", type: "integers"}
-
}
};
Const args = {
Type: "Tuple",
Value: [
{
Name: "Field1",
Type: "String"
},
{
Name: "Field2",
Type: "integer"
}
-
};
Viem.encodefunctiondata (args, function (date) {
// Treat the structure or times here
});
In this example, we create two objects: « Struct ‘and «Args’. The «Struct» object has one field called «value», which is a set of objects with two fields.
application
Transferring the application of structures or short to the «Encodefunctiondata» help program requires the creation of objects corresponding to its structure. By following the syntax and using examples, such as the examples given in this article, you should be able to successfully cause actions that accept the data structured as channel parameters.
