问题 I get a JSON from a client on the successful submit of user details. Some element in the JSON can be skipped since they were not updated. On the Go server side, I have an equivalent struct defined. The server successfully marshals the JSON bytes into the struct. type user struct { Id *int64 `json:",omitempty"` Name *string `json:",omitempty"` Age *int64 `json:",omitempty"` } But for fields which are not recieved from client, unmarshal by default hard-codes nil for string and empty array for

问题 Hi I am working on a rest API in Go and I want the user to pass JSON parameters: Offset int64 `json:"offset"` Limit int64 `json:"limit"` SortBy string `json:"sortby"` Asc bool `json:"asc"` Username string `json:"username"` First_Name string `json:"first_name"` Last_Name string `json:"last_name"` Status string `json:"status"` But they are not always required so for example a user can pass only Offset and ignore the others. He can even send 0 parameters. How can I do this? 回答1: When

JAXB unmarshalling with @XmlMixed Annotation

问题 I have a problem while unmarshalling an XML document. I found good hints here ("JAXB- @XmlMixed usage for reading @XmlValue and @XmlElement") but I wasn't able to adopt this on my code. First.. here is an example of the xml: <test> <content type="text">This is a content text</content> <content type="attributes"> <attributeGroup name="group1"> <attribute name="attr1">value1</attribute> </attributeGroup> <attributeGroup name="group2"> <attribute name="attr2">value2</attribute> <attribute name=

Golang interface{} type misunderstanding

问题 I got a bug in Go when using an interface{} as function parameter type, when given a non-pointer type, and using json.Unmarshal with it. Because a piece of code is worth a thousand words, here is an example: package main import ( "encoding/json" "fmt" ) func test(i interface{}) { j := []byte(`{ "foo": "bar" }`) fmt.Printf("%T\n", i) fmt.Printf("%T\n", &i) json.Unmarshal(j, &i) fmt.Printf("%T\n", i) } type Test struct { Foo string } func main() { test(Test{}) } Which outputs: main.Test
