javascript - 如何在 botpress 自定义组件中获取 json 对象？

Question

我从 botpress 调用一个 api，它返回我需要在我的自定义组件中显示的对象列表，但我总是将它作为字符串 InfaLinkPreview.jsx: "[object Object]"如果我使用 console.log(JSON.parse(this.contentArray)) 我得到下面的异常

Uncaught SyntaxError: Unexpected token o in JSON at position 1
at JSON.parse (<anonymous>)
at eval (eval at render (VM449 lite.bundle.js:10992), <anonymous>:1:18)

看来我在自定义组件中遗漏了一些东西。

          <small className="infaTextTimestamp">{this.getTimestamp()}</small>
        </div>
      )
    }
  }
}

注意:使用botpress v11.9.5

更新 网络响应.. 在这个 JSON 中 session.response 是正确的，但是 responses.text 作为 [object Object ]。因此，在向 InfaLinkPreview 组件提供 session.response 时，不知何故，这是错误的。

请帮我弄清楚 infa-link-preview.js 或 InfaLinkPreview.jsx 文件出了什么问题。

Answer 1

尝试以下 2 个更改，它应该可以工作

{
    type: 'custom',
    module: 'custom-component',
    component: 'InfaLinkPreview',
    text: data.text,
    response: {
        data
    }
}

和

contentArray = JSON.parse(this.props.response.data.session.response)
