使用DIO一次将所有这些字段/文件发送到服务器

Answer 1

从dio的文档中:

“通过FormData将多个文件上传到服务器:”

FormData.fromMap({
    "name": "wendux",
    "age": 25,
    "file": await MultipartFile.fromFile("./text.txt",filename: "upload.txt"),
    "files": [
      await MultipartFile.fromFile("./text1.txt", filename: "text1.txt"),
      await MultipartFile.fromFile("./text2.txt", filename: "text2.txt"),
    ]
});
response = await dio.post("/info", data: formData);
