"unexpected end of JSON input" 当在 POST 请求中传递对象数组时
"unexpected end of JSON input" when an array of objects is passed in POST request
import "github.com/gin-gonic/gin"
func Receive(c *gin.Context) {
// Gets JSON ecnoded data
rawData, err := c.GetRawData()
if err != nil {
return nil, err
}
logger.Info("Raw data received - ", rawData)
}
此代码片段在我传递 Json 对象 {"key":"value"}
时有效,但出现错误:
"unexpected end of JSON input"
当我传递像 [{"key":"val"},{"key": "val"}]
这样的数组作为输入时。
All GetRawData() does 是 return 流数据,因此不会导致您的错误:
// GetRawData return stream data.
func (c *Context) GetRawData() ([]byte, error) {
return ioutil.ReadAll(c.Request.Body)
}
但是,请尝试使用 BindJSON
并反序列化为结构。例如参见 [=14=].
type List struct {
Messages []string `key:"required"`
}
func Receive(c *gin.Context) {
data := new(List)
err := c.BindJSON(data)
if err != nil {
return nil, err
}
}
