主要是以下 {"param":[{"idNo":"152701195712084815","examDate":"2022-01-06","type":"1"}],
         "file":图像的字符串}
 请教一下这个写法对吗？写两行怎样结合的？报文内容怎样处理？第二行应该写还是不应该写？如果写用什么格式？
如果合适请您给写一下。拜托

可以使用socket, 逻辑更简单一些, http post主要就是header和body, header必须为multipart/form-data才能同时post表单域和图片,  参考代码(python的, 但http协议都一样, 转成vpf很简单,全是拼接的字符串):
import socket
import os
 
# 图片路径和文件名
image_path = 'path/to/your/image.jpg'
 
# 服务器地址和端口
HOST, PORT = ", 80
 
# 读取图片内容
with open(image_path, 'rb') as f:
    image_data = f.read()
 
# 图片文件名
image_filename = os.path.basename(image_path)
 
# 创建 socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST, PORT))
 
# 构建请求头
boundary = '----------ThIsIsABoundary'
end_boundary = '--' + boundary + '--\r\n'
body = []
 
# 添加表单域数据
body.append('--' + boundary)
body.append('Content-Disposition: form-data; name="fieldname"')
body.append('')
body.append('value')
 
# 添加图片数据
body.append('--' + boundary)
body.append('Content-Disposition: form-data; name="image"; filename="{0}"'.format(image_filename))
body.append('Content-Type: image/jpeg')
body.append('')
body.append(image_data)
 
# 最后添加结束边界
body.append(end_boundary)
 
# 构建请求体
body = '\r\n'.join(body)
 
# 设置请求头
header = 'POST /upload HTTP/1.1\r\n'
header += 'Host: {0}:{1}\r\n'.format(HOST, PORT)
header += 'Content-Type: multipart/form-data; boundary={0}\r\n'.format(boundary)
header += 'Content-Length: {0}\r\n\r\n'.format(len(body))
 
# 发送请求
s.send(header.encode('utf-8'))
s.send(body.encode('utf-8'))
 
# 接收响应
response = s.recv(1024)
print(response)
 
# 关闭连接
s.close()
