    Is "google/protobuf/struct.proto" the best way to send dynamic JSON over GRPC?

    Based on this proto file.

    I think it is a good solution to use the type.

    The folks with their answers, helped me a lot at the beginning, so I would like to say thanks for your work! :) I really appreciate both solutions! :) On the other hand, I think I found a better one to produce these kinds of .

    Anuj's Solution

    This is a little bit overcomplicated but it can work.

    Luke's Solution

    This is a shorter one but still require more conversion than necessary.

    The solution from my perspective

    My solution will use the official functions from the package which is pretty well documented and user friendly.

    Documentation:https://pkg.go.dev/google.golang.org/protobuf/types/known/structpb

    For example, this code creates a via the function that was designed to do this.

    One of the most important thing, that we should keep in mind when we are building from a is this:

    https://pkg.go.dev/google.golang.org/protobuf/types/known/structpb#NewValue

    For example, if you would like to produce a that has a string list in its JSON form, you should create the following

    Sorry for the long post, I hope it makes your work easier with and ! :)

    Struct protobuf

    Package structpb contains generated types for google/protobuf/struct.proto.

    The messages (i.e., Value, Struct, and ListValue) defined in struct.proto are used to represent arbitrary JSON. The Value message represents a JSON value, the Struct message represents a JSON object, and the ListValue message represents a JSON array. See https://json.org for more information.

    The Value, Struct, and ListValue types have generated MarshalJSON and UnmarshalJSON methods such that they serialize JSON equivalent to what the messages themselves represent. Use of these types with the "google.golang.org/protobuf/encoding/protojson" package ensures that they will be serialized as their JSON equivalent.

    Conversion to and from a Go interface ¶

    The standard Go "encoding/json" package has functionality to serialize arbitrary types to a large degree. The Value.AsInterface, Struct.AsMap, and ListValue.AsSlice methods can convert the protobuf message representation into a form represented by interface{}, map[string]interface{}, and []interface{}. This form can be used with other packages that operate on such data structures and also directly with the standard json package.

    In order to convert the interface{}, map[string]interface{}, and []interface{} forms back as Value, Struct, and ListValue messages, use the NewStruct, NewList, and NewValue constructor functions.

    Example usage ¶

    Consider the following example JSON object:

    { "firstName": "John", "lastName": "Smith", "isAlive": true, "age": 27, "address": { "streetAddress": "21 2nd Street", "city": "New York", "state": "NY", "postalCode": "10021-3100" }, "phoneNumbers": [ { "type": "home", "number": "212 555-1234" }, { "type": "office", "number": "646 555-4567" } ], "children": [], "spouse": null }

    To construct a Value message representing the above JSON object:

    m, err := structpb.NewValue(map[string]interface{}{ "firstName": "John", "lastName": "Smith", "isAlive": true, "age": 27, "address": map[string]interface{}{ "streetAddress": "21 2nd Street", "city": "New York", "state": "NY", "postalCode": "10021-3100", }, "phoneNumbers": []interface{}{ map[string]interface{}{ "type": "home", "number": "212 555-1234", }, map[string]interface{}{ "type": "office", "number": "646 555-4567", }, }, "children": []interface{}{}, "spouse": nil, }) if err != nil { ... // handle error } ... // make use of m as a *structpb.Value

    type ListValue struct { Values []*Value `protobuf:"bytes,1,rep,name=values,proto3" json:"values,omitempty"` }

    `ListValue` is a wrapper around a repeated field of values.

    The JSON representation for `ListValue` is JSON array.

    NewList constructs a ListValue from a general-purpose Go slice. The slice elements are converted using NewValue.

    AsSlice converts x to a general-purpose Go slice. The slice elements are converted by calling Value.AsInterface.

    `Struct` represents a structured data value, consisting of fields which map to dynamically typed values. In some languages, `Struct` might be supported by a native representation. For example, in scripting languages like JS a struct is represented as an object. The details of that representation are described together with the proto support for the language.

    The JSON representation for `Struct` is JSON object.

    NewStruct constructs a Struct from a general-purpose Go map. The map keys must be valid UTF-8. The map values are converted using NewValue.

    AsMap converts x to a general-purpose Go map. The map values are converted by calling Value.AsInterface.

    type Value struct { Kind isValue_Kind `protobuf_oneof:"kind"` }

    `Value` represents a dynamically typed value which can be either null, a number, a string, a boolean, a recursive struct value, or a list of values. A producer of value is expected to set one of that variants, absence of any variant indicates an error.

    The JSON representation for `Value` is JSON value.

    NewBoolValue constructs a new boolean Value.

    NewListValue constructs a new list Value.

    func NewNullValue() *Value

    NewNullValue constructs a new null Value.

    NewNumberValue constructs a new number Value.

    NewStringValue constructs a new string Value.

    NewStructValue constructs a new struct Value.

    NewValue constructs a Value from a general-purpose Go interface.

    When converting an int64 or uint64 to a NumberValue, numeric precision loss is possible since they are stored as a float64.

    func (x *Value) AsInterface() interface{}

    AsInterface converts x to a general-purpose Go interface.

    Calling Value.MarshalJSON and "encoding/json".Marshal on this output produce semantically equivalent JSON (assuming no errors occur).

    Floating-point values (i.e., "NaN", "Infinity", and "-Infinity") are converted as strings to remain compatible with MarshalJSON.
