javascript - 创建 Assets 时内容丰富的内容管理 API 错误 422

Question

我正在尝试使用 Contentful Content Management API 创建和发布图像作为 Assets ，但到目前为止没有成功，我已经能够成功创建和发布条目，但我无法弄清楚为什么 Assets 不起作用。这是我创建 Assets 的代码。最终目标是使其适用于一系列图像/附件，但我试图在处理多个图像/附件之前使其只处理一个图像/附件。

  makeAsset = async (item) => {
    try {
      var MClient = createClient({
        accessToken: process.env.REACT_APP_CONTENTFUL_MANAGEMENT_ACCESS_TOKEN,
      });
      let space = await MClient.getSpace(
        process.env.REACT_APP_CONTENTFUL_API_SPACE
      );
      let environment = await space.getEnvironment(
        process.env.REACT_APP_CONTENTFUL_ENVIRONMENT
      );

      const asset = await environment.createAsset({
        fields: {
          title: {
            "en-US": item.imgNames[0],
          },
          file: {
            "en-US": {
              fileName: item.images[0].name,
              contentType: item.images[0].type,
              uploadFrom: item.imgUrls[0],
            },
          },
        },
      });

      const processedAsset = await asset.processForAllLocales();
      processedAsset.publish();

控制台中的错误是这样的:

我一直在尝试搜索其他示例，因为文档不完整，并且没有一个示例适合我。我尝试过的一种解决方案是使用 fs.createReadStream() 函数，但该函数已从 React 中删除。

@stefan judis，我使用了示例中的代码，其中一个函数在较新的版本中已被弃用，所以我想我应该冒险更换一些东西，然后它就起作用了。为了供其他遇到此问题的人将来引用，这里是解决我的问题的解决方案:

makeAsset = async (item) => {
try {
  //Contentful API Call
  var MClient = createClient({
    //Fetch access token from environment variables
    accessToken: process.env.REACT_APP_CONTENTFUL_MANAGEMENT_ACCESS_TOKEN,
  });
  //API call that requests the specified space
  let space = await MClient.getSpace(
    process.env.REACT_APP_CONTENTFUL_API_SPACE
  );
  let environment = await space.getEnvironment(
    process.env.REACT_APP_CONTENTFUL_ENVIRONMENT
  );

  const file = item.images[0];
  const contentType = file.type;
  const fileName = file.name;
  let asset = await environment.createAssetFromFiles({
    fields: {
      title: {
        "en-US": fileName,
      },
      file: {
        "en-US": {
          contentType,
          fileName,
          file,
        },
      },
    },
  });
  asset = await asset.processForAllLocales();
  asset.publish();
} catch(error) {
  console.log(error);
}
}
