发出包含post数据和文件上载的http多部分请求

Question

我试图发送一个帖子请求到一个php文件，该文件有帖子数据和文件上传，这里是我发送的内容，设置标题的代码，我有的php文件，以及我从php中得到的东西file：（[图像文件内容]是我正在发送的图像文件二进制数据的占位符）

我的问题是_POST

//我正在向服务器发送的数据：

--boundary
content-disposition: post; name='param1'

value1
--boundary
content-disposition: post; name='field2'

value2
--boundary
content-disposition: post; name='field3'

value3
--boundary
content-disposition: form-data; name='file'; filename='app/native/assets/sampleFile.jpg'
Content-Type: image/jpg
Content-Transfer-Encoding: binary

[image file content]
--boundary--

-----------------------------------------------------

对于我的标题，我有：

request.setRawHeader("Content-Type", "mulipart/form-data, boundary=boundary");
//data holds the string above
request.setRawHeader("Content-Length", QString::number(data.length()).toAscii());

php文件：

<?php
  echo "\npost:\n\n";
  print_r($_POST);

  echo "\nfiles:\n\n";
  print_r($_FILES);
?>

php文件的结果：

post:

Array

files:

Answer 1

试试像这样的东西

--boundary
Content-Disposition: form-data; name="param1"

value1
--boundary
Content-Disposition: form-data; name="field2"

value2
--boundary
Content-Disposition: form-data; name="field3"

value3
--boundary
Content-Disposition: form-data; name="file"; filename="app/native/assets/sampleFile.jpg"
Content-Type: image/jpg
Content-Transfer-Encoding: binary

[image file content]
--boundary--

request.setRawHeader("Content-Type", "multipart/form-data; boundary=boundary");
