从url读json

标签: json go google-sheets

端点是在Google SpreadSheet中创建的,其位于:

url01 := "https://spreadsheets.google.com/feeds/list/168xdxefP3gGnrTGg2hwJoeRVfmbEuTB5plFTyd6I5Qo/1/public/values?alt=json"

Git repo就在这里......在我修复它的时候,我将保留更新的代码。我的预感是我在导入文件时搞砸了结构。代码什么都不打印。那么,请问我能找到什么问题的建议。

        package main

import (
    "encoding/json"
    "fmt"
    "net/http"
)

type GSSS struct {
    Feed GSSSfeed `json:"feed"`
}

type GSSSfeed struct {
    Version string   `json:"version"`
    TITLE   GSSTitle `json:"title"`
    // Entry   []GSSSEntry `json:"entry"`
}
type GSSTitle struct {
    T string `json:"t"`
}

func main() {
    url01 := "https://spreadsheets.google.com/feeds/list/168xdxefP3gGnrTGg2hwJoeRVfmbEuTB5plFTyd6I5Qo/1/public/values?alt=json"
    //url02 := "https://spreadsheets.google.com/feeds/list/168xdxefP3gGnrTGg2hwJoeRVfmbEuTB5plFTyd6I5Qo/2/public/values?alt=json"
    //url03 := "https://spreadsheets.google.com/feeds/list/168xdxefP3gGnrTGg2hwJoeRVfmbEuTB5plFTyd6I5Qo/3/public/values?alt=json"
    //url04 := "https://spreadsheets.google.com/feeds/list/168xdxefP3gGnrTGg2hwJoeRVfmbEuTB5plFTyd6I5Qo/4/public/values?alt=json"
    //url05 := "https://spreadsheets.google.com/feeds/list/168xdxefP3gGnrTGg2hwJoeRVfmbEuTB5plFTyd6I5Qo/5/public/values?alt=json"
    println("=============  starting main =============")

    // res, err := http.Get("https://www.citibikenyc.com/stations/json")
    res, err := http.Get(url01)
    if err != nil {
        panic(err.Error())
    }

    // body, err := ioutil.ReadAll(res.Body)
    // if err != nil {
    //  panic(err.Error())
    // }

    var m GSSS
    // err := json.Unmarshal(body, &m)
    //json.NewDecoder(res.Body).Decode(&m)
    // json.NewDecoder([]byte(body)).Decode(&m)

    // json.NewDecoder([]byte(res.Body)).Decode(&m)
    json.NewDecoder(res.Body).Decode(&m)

    //err := json.Unmarshal([]byte(body), &m)
    if err != nil {
        fmt.Println("Whoops...:", err)
    }

    fmt.Println("============  about to print m ============")
    fmt.Println(m.Feed.TITLE.T)
    fmt.Println("============  about to print m2 ============")
    fmt.Println(m.Feed)
    fmt.Println("============  about to print m3 ============")
    fmt.Println(m)
    fmt.Println("============  about to print m4 ============")
}

正如已经指出的那样,您对a的定义是错误的。

这样做效果更好:
