curl -F c＃上传文件

Question

我有一个curl语句，它有-F。我需要为cURL -F做些什么？通过将以下代码添加到下面的代码中，我已经能够通过将-b传递到标题来获得工作request.Headers.Add(HttpRequestHeader.Cookie, (header));

要将documentfile和xml添加到内容变量中，我会执行以下操作，但这不起作用并给出错误。根据供应商的规格，你必须在xml =和数据之间有一个空格。

byte[] byteData = Bytes.Combine(Bytes.ConvertToBytesUTF8("documentFile="), File.ReadAllBytes(file)); 
string postData = new StreamReader(file2).ReadToEnd(); 
postData = string.Format(postData, documentpath,folderid); 
byteData = Bytes.Combine(byteData,Bytes.ConvertToBytesUTF8("xml= ")); 
byteData = Bytes.Combine(byteData,Bytes.ConvertToBytesUTF8(postData); 
byte[] content = byteData; 

public class Bytes 
{ 
    public static byte[] ConvertToBytesUTF8(string postData) 
    { 
     byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(postData); 
     return byteArray; 
    } 

    public static byte[] Combine(params byte[][] arrays) 
    { 
     byte[] rv = new byte[arrays.Sum(a => a.Length)]; 
     int offset = 0; 
     foreach (byte[] array in arrays) 
     { 
      System.Buffer.BlockCopy(array, 0, rv, offset, array.Length); 
      offset += array.Length; 
     } 
     return rv; 
    } 
} 

如果卷曲包含-d代替-FI一直在做下面的内容字节传递到变量content然而，在任何卷曲我不得不使用它只有过1 -d所以我从来没有像上面所做的那样结合字节。

request = WebRequest.Create(connectionstring); 
request.Method = "POST"; 
request.ContentType = "application/x-www-form-urlencoded"; 
if (content != null) 
{ 
    request.ContentLength = content.Length; 
} 

Stream dataStream = request.GetRequestStream(); 

if (content!=null && content.Length > 0) 
{ 
    dataStream.Write(content, 0, content.Length); 
} 

dataStream.Close(); 

WebResponse response = request.GetResponse(); 

dataStream = response.GetResponseStream(); 

StreamReader reader = new StreamReader (dataStream); 

string responseReader = reader.ReadToEnd(); 

reader.Close(); 
dataStream.Close(); 
response.Close(); 

return responseReader; 

我需要为cURL -F做些什么？我尝试使用将数据传递到标题和请求中的方法，并且都没有用于传递-F字段。我从接收器收到错误Ill-formed request parameter cannot be converted to Java field type.它说问题出在documentFile上。我还将documentFile和xml部分的两个字节紧接在一起。这是问题吗？我需要在两者之间的某种分隔符吗？这也是我第一次有多个文件一次通过。

下面是一个使用WebRequest

curl -k -X POST 
-b "ssoGlobalSessionID=YOUR_SESSION_ID" 
–F "documentFile=@/Users/User/Test.PDF" 
–F "xml=XML_REQUEST.XML" 
"url" 

Answer 1

要复制的卷曲

curl -k -X POST 
-b "ssoGlobalSessionID=YOUR_SESSION_ID" 
–F "documentFile=@c:/Users/User/Test.PDF" 
–F "xml=XML_REQUEST.XML" 
"url" 

这本声明卷曲声明我感兴趣再现的是，工作在C＃

StringBuilder contents = new StringBuilder(); 
byte[] content=null; 
string header = "ssoGlobalSessionID=YOUR_SESSION_ID"; 
string documentfile = "c:/Users/User/Test.PDF"; 
string filename = Path.GetFileName(file); 
static string boundary = Guid.NewGuid().ToString(); 
WebRequest request = WebRequest.Create(url); 
request.Method = "POST"; 
request.ContentType = string.Format("multipart/form-data; boundary={0}, boundary); 
request.Headers.Add(HttpRequestHeader.Cookie, header); 
AddContentFileCurl(File.ReadAllBytes(documentfile), "documentFile", filename); 
AddContentFormCurl(System.Text.Encoding.ASCII.GetBytes("XMLMARKUP"),"xml"); 
LastFileAddedCurl(); 
if (content != null) 
{ 
    request.ContentLength = content.Length; 
} 

Stream dataStream = request.GetRequestStream(); 

if (content!=null && content.Length > 0) 
{ 
    dataStream.Write(content, 0, content.Length); 
} 

dataStream.Close(); 

WebResponse response = request.GetResponse(); 

dataStream = response.GetResponseStream(); 

StreamReader reader = new StreamReader (dataStream); 

string responseReader = reader.ReadToEnd(); 

reader.Close(); 
dataStream.Close(); 
response.Close(); 

代码

我为此创建的3个方法和我从另一个帖子获得的一个类为MIMET下面复制了ypes。

public void AddContentFileCurl(byte[] file, string name, string filename) 
    { 
     string header = string.Format("--{0}", boundary); 
     string fileContentType = MIMEAssistant.GetMIMEType(filename);      
     contents.AppendLine(header); 
     string fileHeader=String.Format("Content-Disposition: form-data; name=\"{0}\"; filename=\"{1}\"",name,filename); 
     string fileData = Encoding.UTF8.GetString(file); 
     contents.AppendLine(fileHeader); 
     contents.AppendLine(String.Format("Content-Type: {0}", fileContentType)); 
     contents.AppendLine(); 
     contents.AppendLine(fileData); 
    } 

public void AddContentFormCurl(byte[] file, string name) 
    { 
     string header = string.Format("--{0}", boundary); 
     contents.AppendLine(header); 
     string fileHeader = String.Format("Content-Disposition: form-data; name=\"{0}\"", name); 
     string fileData = Encoding.UTF8.GetString(file); 
     contents.AppendLine(fileHeader); 
     contents.AppendLine(); 
     contents.AppendLine(fileData); 
    } 

public void LastFileAddedCurl() 
    { 
     string footer = string.Format("--{0}--", boundary);   
     contents.AppendLine(footer); 
     string cstring = contents.ToString(); 
     byte[] bytes = Encoding.UTF8.GetBytes(cstring); 
     if (content != null) 
     { 
      content = Bytes.Combine(content, bytes); 
     } 
     else 
     { 
      content = bytes; 
     } 
    }
