  -H 'Content-Type: multipart/form-data' \
  -F product_file=@products.csv

注意：Content-Type 需要传递为 multipart/form-data

Go 服务读取文件CSV文件

file, fileHeader, _ := r.FormFile("product_file")
defer file.Close()
fmt.Println(fileHeader.Filename) // products.csv
fmt.Println(fileHeader.Header) // map[Content-Disposition:[form-data; name="product_file"; filename="products.csv"] Content-Type:[text/csv]]
fmt.Println(fileHeader.Size) // 1182


// print csv body
fileBytes, _ := ioutil.ReadAll(file)
fmt.Println(string(fileBytes))

// to csv object
csvRead := csv.NewReader(file)
records, _ := csvRead.ReadAll()
for _, record := range records {
    fmt.Println(record)
}
