这是数组

parts:[map[content:Phillip,

This section pertains to terminated employees who are paid out in the year following the termination event.  The way the tax law works, the tax basis for your share distribution will be based on the closing stock price the day preceding notification to the transfer agent.  As such, we will distribute net shares calculating the proper withholding at fair market value the day prior to notifying the transfer agent.  We will be distributing the shares reflected on your 9/30/01 statement (6,606 shares plus cash for fractional shares).  If you would prefer to settle the taxes with a personal check, we can distribute gross shares.  Please let me know you preference.

As you know, we are in the process of transferring recordkeeping services from NTRC to Hewitt.  As such, we have a CPA, Larry Lewis, working with us to audit and set up transition files.  He has become our department expert on the PSA account (much more knowledgeable than myself)  and the various plan provision amendments.  If you would like, we can set up a conference call with you, myself, and Larry to go over the payment methodology.  Please let me know a date and time that is convenient for you.

Thanks,

Renee

Renee,

Thank you for digging in to the issue of Deferred Phantom Stock Units.  It is clear that the payment will be made in shares.  However, I still don't understand which date will be used to determine the value and calculate how many shares.  The plan document under VII.  Amount of Benefit Payments reads "The value of the shares, and resulting payment amount will be based on the closing price of Enron Corp. common stock on the January 1 before the date of payment, and such payment shall be made in shares of Enron Corp. common stock."  Can you help me interpret this statement and work through the numbers on my account.

Thank you,

 Phillip Allen

我遇到的问题是试图“满足”我已经尝试过类似的东西

t := v["parts"][0].(map[string]interface{})

这并没有像其他一些让我陷入困境的事情那样奏效。

该部分位于另一个映射字符串接口(interface)内。

这是我不断收到的错误

panic: interface conversion: interface is []interface {}, not map[string]interface {}

这是我正在解析的 JSON 对象。

这是代码。

最佳答案

请张贴您尝试过的和您正在尝试做的实际示例。

映射数组和数组映射的行为与任何其他类型一样。

在您的示例中，看起来您想要一个 map[string][]map[string]interface{} 但您有 map[string][]interface{} code>，你的界面内容是一个[]interface{}

这里有一些使用 map /接口(interface)/数组/slice 的例子+你展示的失败。 ( http://play.golang.org/p/gmH_nVPppx )

package main

import "fmt"

type Content struct {
        name string
}

func main() {
        arrayOfMap := [2]map[string]Content{
                {"part1": {name: "Philip"}},
                {"part2": {name: "John"}},
        }
        fmt.Printf("%s\n", arrayOfMap[0]["part1"].name)

        mapOfArray := map[string][2]Content{
                "parts": {
                        {name: "Philip"},
                        {name: "John"},
                },
        }
        fmt.Printf("%s\n", mapOfArray["parts"][0].name)

        mapOfArrayOfMap := map[string][2]map[string]Content{
                "parts": {
                        {"subpart": Content{name: "Philips"}},
                },
        }
        fmt.Printf("%s\n", mapOfArrayOfMap["parts"][0]["subpart"].name)

        mapOfArrayOfInterface := map[string][2]interface{}{
                "parts": {
                        map[string]interface{}{"content": Content{name: "Philips"}},
                },
        }
        fmt.Printf("%s\n", mapOfArrayOfInterface["parts"][0].(map[string]interface{})["content"].(Content).name)

        mapOfArrayOfSliceInterface := map[string][2][]interface{}{
                "parts": {
                        {
                                map[string]interface{}{
                                        "content": Content{name: "Philips"},
                                },
                        },
                },
        }
        fmt.Printf("%s\n", mapOfArrayOfSliceInterface["parts"][0][0].(map[string]interface{})["content"].(Content).name)

        v := map[string][]interface{}{
                "parts": []interface{}{
                        0: []interface{}{nil},
                },
        }
        // This will fail as shown in the given example.
        fmt.Printf("%s\n", v["parts"][0].(map[string]interface{}))
}
