How to send a Map Object With FormData to .NET API?

当我尝试发送带有 FormData 的地图对象时,出现类似这样的错误;

TS2345: Argument of type 'Map<number, number>' is not assignable to parameter of type 'string | Blob'.   Type 'Map<number, number>' is missing the following properties from type 'Blob': type, arrayBuffer, slice, stream, tex

我如何将带有表单数据的对象发送到我的 .net API?

转换为json并像这样发送

var content = '{ json data here }';
var blob = new Blob([content], { type: "text/json"});
formData.append("jsonData", blob);

new Blob([JSON.stringify({
   description: 'description',
})], {
   type: 'application/json'
})
