Antd上传控件需要动作功能，但我不需要它 [英] action function is required with antd upload control, but I dont need it
本文介绍了Antd上传控件需要动作功能，但我不需要它的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我使用的是Ant设计组件，我有一个上传输入： https://ant.design/components/upload/
根据文档，道具上需要采取行动。
但是，我不需要在上传时将文件发布到URL，我需要将整个表单提交到REST端点(检查handlesubmit函数)
尝试浏览文档时，我使用HandlChange事件将文件添加到状态，但状态永远不会完成，因此该行永远不会命中。
我在这里遗漏了什么？

推荐答案
TL；DR
用模拟的成功上传覆盖<Upload/>默认的Upload AJAX实现。
完整答案
您似乎试图将andt的<Upload/>组件简单地用作文件选择器，因为您是自己将文件附加到formData。从未触及status === "done"的原因是因为文件并未真正上载到任何地方。因此，您不需要像OOB那样自动上载文件。
您所需要的就是
onChange将向您发送所选文件，您可以将其保存在状态树中的某个位置。<Upload/>呈现另一个组件(rc-upload)作为其子组件，该组件处理实际的AJAX上传。
您可以通过将customRequest道具传递给<Upload/>(该道具将传递给rc-upload组件)来覆盖此行为。
您可以看到here哪些选项被传递给请求函数。 下面是一个虚拟请求函数的实现：
const dummyRequest = ({ file, onSuccess }) => {
setTimeout(() => {
onSuccess("ok");
}, 0);
};
<Upload customRequest={dummyRequest}/>onChange仍将被触发，但这次的状态为"done"，因为伪请求函数模拟成功上载的流。
