React js读取文件以获取

Question

我必须读取一个json文件，我遵循以下代码：stackoverflow

尝试注释中显示的示例，但它对我不起作用。

我必须阅读本地存储的文件，但没有成功。

你能帮我吗？

代码：

fetch("/user.json")
  .then(res => res.json())
  .then(res => res.results)
  .then(res => {
    console.log(res);
    let u = res.map((suggestion, i) => ({
      label: suggestion.email,
      name: suggestion.name.first,
      surname: suggestion.name.last,
      address: suggestion.location.street.name,
      email: suggestion.email,
      picture: suggestion.picture.thumbnail
    }));
    let options =
      inputLength === 0
        ? []
        : u.filter(suggestion => {
            const keep =
              count < 5 &&
              suggestion.label &&
              suggestion.label.slice(0, inputLength).toLowerCase() ===
                inputValue;
            if (keep) count += 1;
            return keep;
          });
    this.setState({ options });
  })
  .catch(e => console.log("Er:", e));

您可以只使用import或要求如下：

const data = require("./myFile.json")
import data from "./myFile.json"
