Golang JSON编码，可用于JavaScript解析 [英] Golang JSON encoding for parsing with JavaScript

问题描述

我有一个这样的结构:

type User struct {
  Login         string    `json:",string"`
  PasswordNonce Nonce     `json:",string"`
  PasswordHash  HashValue `json:",string"`
  CreatedOn     time.Time `json:",string"`
  Email         string    `json:",string"`
  PhoneNumber   string    `json:",string"`
  UserId        Id        `json:",string"`
}

生成JSON并将其发送的代码如下:

The code that generates the JSON and sends it is the following:

func AddUserHandler(w http.ResponseWriter, r *http.Request) {
    var userRecord model.User
    encoder := json.NewEncoder(w)
    err = encoder.Encode(userRecord)
    if err != nil {
        panic(err)
    }
}

当我使用内置的JSON编码器中的Golang对其进行编码时，字段名称显示时不带引号，这会阻止node.js中的JSON.parse函数读取内容. 有人知道解决方案吗?

When I encode it with the Golang built in JSON encoder, the field names appear without quotes, which prevents the JSON.parse function in node.js from reading the content. Does anyone know a solution to that?

谢谢！

推荐答案

这是我的错误.问题出在Javascript代码中. 我正在使用node.js请求包，它似乎默认解析JSON响应.在以下代码中，response.body已经是一个包含JSON字符串的解析内容的映射:

It was my mistake. The problem was in the Javascript code. I am using the node.js request package, and it seems to parse JSON responses by default. In the following code, response.body is already a map containing the parsed contents of the JSON string:

var request = require('request');

var options = {
    uri: 'http://localhost:3000/AddUser',
    method: 'POST',
    json: {}
};

request(options, function(error, response, body) {
    console.log(error)
    console.log(response.body)
    console.log(response.body["UserId"])
    data = response.body
    // data = JSON.parse(response.body) gives an error...
});
