问题内容

我正在尝试使用 Plaid 开发环境来测试 Plaid API。我正在为 plaid 创建一个命令行 cli，所以我目前不需要服务器，所以目前我使用 Go 生成一个链接令牌并将该令牌呈现为 HTML blob。当我在浏览器中打开该 HTML 文件并单击“链接帐户”按钮时，它会无限期挂起。

下面是生成链接并呈现为 HTML 的 go 代码：

package main

import (
    "context"
    _ "embed"
    "html/template"
    "log"
    "os"
    "time"

    "github.com/plaid/plaid-go/plaid"
    "github.com/vrischmann/envconfig"
)

type config struct {
    PlaidApi struct {
        ClientId string `envconfig:"PLAID_CLIENT_ID"`
        Secret   string `envconfig:"PLAID_SECRET"`
    }
}

//go:embed token.html.tmpl
var tokenPage string

func main() {
    cfg := config{}

    if err := envconfig.Init(&cfg); err != nil {
        log.Fatalf("failed to load config from environment: %s", err)
    }

    ctx := context.TODO()
    plaidCfg := plaid.NewConfiguration()
    plaidCfg.UseEnvironment(plaid.Development)
    cli := plaid.NewAPIClient(plaidCfg)
    phoneNumber := "+1 888 888-8888"
    user := plaid.LinkTokenCreateRequestUser{
        ClientUserId: "1",
        PhoneNumber:  &phoneNumber,
    }
    request := plaid.NewLinkTokenCreateRequest(
        "Personal Finance App",
        "en",
        []plaid.CountryCode{plaid.COUNTRYCODE_US},
        user,
    )
    request.SetProducts([]plaid.Products{plaid.PRODUCTS_TRANSACTIONS})
    request.SetSecret(cfg.PlaidApi.Secret)
    request.SetClientId(cfg.PlaidApi.ClientId)
    linkTokenCreateResp, _, err := cli.PlaidApi.LinkTokenCreate(ctx).LinkTokenCreateRequest(*request).Execute()
    if err != nil {
        if pErr, err := plaid.ToPlaidError(err); err == nil {
            log.Printf("Error from plaid: %s", pErr.ErrorMessage)
        }
        log.Fatalf("failed to get link request: %s", err.Error())
    }
    log.Printf("link token: %s", linkTokenCreateResp.GetLinkToken())

    tmplate, err := template.New("token.html").Parse(tokenPage)
    if err != nil {
        log.Printf("Html tmplate:\n%s", tokenPage)
        log.Fatalf("Failed to create HTML template: %s", err)
    }

    page, err := os.CreateTemp("", "catnip_*.html")
    if err != nil {
        log.Fatalf("Failed to create temp file: %s", err)
    }
    defer os.Remove(page.Name())
    data := struct {
        LinkToken string
    }{LinkToken: linkTokenCreateResp.LinkToken}
    if err := tmplate.Execute(page, data); err != nil {
        log.Printf("template data: %#v", data)
        log.Printf("html template:\n%#v", tokenPage)
        log.Fatalf("Failed to render token page: %s", err)
    }

    log.Printf("token page path:\n%s", page.Name())
    time.Sleep(2 * time.Minute)
}

这是模板（token.html.tmpl）：

<button id="link-button">Link Account</button>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script src="https://cdn.plaid.com/link/v2/stable/link-initialize.js"></script>
<script type="text/javascript">
(async function($) {
  var handler = Plaid.create({
    // Create a new link_token to initialize Link
    token: "{{ .LinkToken }}",
    onLoad: function() {
        console.log("link token: '{{ .LinkToken }}")
    },
    onSuccess: function(public_token, metadata) {
        console.log("Success!");
    },
    onExit: function(err, metadata) {
      if (err != null) {
          console.log(err);
      }
    },
    onEvent: function(eventName, metadata) {}
  });

  $('#link-button').on('click', function(e) {
    handler.open();
  });
})(jQuery);
</script>
