Question

我正在开发上传文件的泽西网络服务。我已经为此编写了代码，但每当我点击var getData = function() { return new Promise((resolve, reject) => { setTimeout(() => { resolve(42); }, 500); }) } var getDataMoreData = function() { return new Promise((resolve, reject) => { setTimeout(() => { resolve(43); }, 300); }) } getData() .then((data) => console.log('Data', data)) .then(getDataMoreData) .then((data) => console.log('data--', data));的提交按钮上传文件时，就会抛出错误404资源找不到。

我不知道这段代码中我错在哪里请帮我改进一下。

提前致谢。
