我的要求是调用第二个 API（服务 B）作为来自经过身份验证的用户对服务 A 的单个请求的一部分。

我正在通过一个计划的项目练习 go-swagger 框架。我试图实现的一点是从微服务 A 到微服务 B 的真实调用。我在没有身份验证的情况下实现了，但无法验证这个内部调用。我在微服务 A 端
遇到错误并且服务停止。我还在微服务 B 端EOF看到错误。runtime error: index out of range [1] with length 1

以下是与 ms-B 通信的 ms-A（遵循 goswagger 文档）的代码：

transport := httptransport.New(apiclient.DefaultHost, apiclient.DefaultBasePath, apiclient.DefaultSchemes)
clientm := apiclient.New(transport, strfmt.Default)
bearerTokenAuth:= httptransport.BearerToken(os.Getenv("Authorization"))

resp, err := clientm.Show.Show(show.NewShowParams(),bearerTokenAuth)
if err != nil {
    log.Fatal(err)
}
fmt.Printf("%#v\n", resp.Payload.Prompt)

微服务 B 中的 Show 端点是测试此内部通信的简单入口点。我确实为 yaml 文件中的路径添加了安全性，如下所示：

/show:
    get:
      description: "To test the entrypoint"
      operationId: "show"
      tags:
        - "show"
      security:
        - Bearer: [ ]
      responses:
        200:
          description: "Success response on hiting endpoint"
          schema:
            $ref: "#/definitions/Show"
        400:
          description: Bad Request
        404:
          description: items not found
        500:
          schema:
            type: string
          description: Server error

错误

微服务-A 错误

在查看了参数和上述错误之后，我终于解决了这个问题，现在它可以工作了。

这里我改变的是服务A中的代码：

    //token received for user authentication by service-A
    bearerHeader := params.HTTPRequest.Header.Get("Authorization")
    
    //connection with service-B client
    transport := httptransport.New(apiclient.DefaultHost,apiclient.DefaultBasePath,apiclient.DefaultSchemes)
    clientm := apiclient.New(transport, strfmt.Default)
    
    //spliting the key and token(string) and pass only the token part
    bearerTokenAuth:= httptransport.BearerToken(strings.Split(bearerHeader, " ")[1])
    //receive response of the service-B endpoint
    resp, err := clientm.Show.Show(show.NewShowParams(),bearerTokenAuth)
    if err != nil {
        log.Fatal(err)
    }
    
    fmt.Printf("%#v\n", resp.Payload.Prompt)
