我收到错误消息“找不到变量uploadImageAsync”

uploadImageAsync = async (uri) => {
  console.log("In upload image asnyc!");
}


这就是我所说的。

_handleImagePicked = async pickerResult => {
let uploadResponse, uploadResult;

  this.setState({ uploading: true });

  if (!pickerResult.cancelled) {
    uploadResponse = await uploadImageAsync(pickerResult.uri);
    uploadResult = await uploadResponse.json();
    this.setState({ image: uploadResult.location });
  }
    this.setState({ uploading: false });
};


我该如何解决?

到目前为止,我已经尝试过:

async function uploadImageAsync(uri) {


我也尝试过:

async uploadImageAsync(uri) {

最佳答案

如果uploadImageAsync函数在同一组件中定义,则需要调用this.uploadImageAsync

否则,您必须在另一个模块中import

或在同一文件中的组件外部定义函数。
