FormData

FormData 用于创建通过 APIRequestContext 发送的表单数据。

方法​

追加​

Added in: v1.44 formData.Append

向FormData对象中的现有键追加一个新值，如果该键不存在则添加该键。文件值可以作为Path或FilePayload传递。可以添加多个同名字段。

FormData.Set()和FormData.Append()的区别在于，如果指定的键已存在，FormData.Set()会用新值覆盖所有现有值，而FormData.Append()会将新值追加到现有值集的末尾。

var multipart = Context.APIRequest.CreateFormData();
// Only name and value are set.
multipart.Append("firstName", "John");
// Name, value, filename and Content-Type are set.
multipart.Append("attachment", new FilePayload()
{
    Name = "pic.jpg",
    MimeType = "image/jpeg",
    Buffer = File.ReadAllBytes("john.jpg")
});
// Name, value, filename and Content-Type are set.
multipart.Append("attachment", new FilePayload()
{
    Name = "table.csv",
    MimeType = "text/csv",
    Buffer = File.ReadAllBytes("my-tble.csv")
});
await Page.APIRequest.PostAsync("https://localhost/submit", new() { Multipart = multipart });

用法

FormData.Append(name, value);
