使用 SOAP 使用 WCF 服务将图像从 iPhone 上传到服务器 [英] Upload image from iPhone to server using WCF service using SOAP

问题描述

我正在为我的应用程序使用 wcf SOAP 服务，我发送如下请求.

hiii, i'm using wcf SOAP services for my app and i send the request like below.

postStr = [NSString stringWithFormat:@"<?xml version="1.0"?>
"
           "<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
"
           "<s:Body>
"
           "<InsUpdDelActivityInfo xmlns="http://tempuri.org/">
"
           "<objEventsContent xmlns:d4p1="http://schemas.datacontract.org/2004/07/iCampuslite.Model.ActivityStream" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
"
           "<d4p1:ActCommentId i:nil="true" />
"
           "<d4p1:ActSubTypeCd i:nil="true" />
"
           "<d4p1:ActType>Status</d4p1:ActType>
"
           "<d4p1:ActTypeCd>1</d4p1:ActTypeCd>

           "<d4p1:ActivityAnswersList />

           "<d4p1:ActivityComments />

           "<d4p1:ActivityId i:nil="true" />
"
           "<d4p1:ActivityLike />
"
           "<d4p1:ActivityName>%@</d4p1:ActivityName>
"
           "<d4p1:ActivityStreamImagesBytes>%@</d4p1:ActivityStreamImagesBytes>
"
           "<d4p1:AnswerDesc i:nil="true" />
"
           "<d4p1:AnswerId>0</d4p1:AnswerId>
"
           "<d4p1:CommentDesc i:nil="true" />
"
           "<d4p1:CommentId i:nil="true" />
"
           "<d4p1:CreatedUserId>%@</d4p1:CreatedUserId>
"
           "<d4p1:CreatedUserName i:nil="true" />
"
           "<d4p1:FileOrLinkName i:nil="true" />
"
           "<d4p1:IsLiked>0</d4p1:IsLiked>
"
           "<d4p1:IsTotalSchool i:nil="true" />
"
           "<d4p1:LikeCount>0</d4p1:LikeCount>
"
           "<d4p1:LinkImage i:nil="true" />
"
           "<d4p1:ObjTypeCdId i:nil="true" />
"
           "<d4p1:ObjTypeId i:nil="true" />
"
           "<d4p1:OperationMode>I</d4p1:OperationMode>
"
           "<d4p1:OperationType i:nil="true" />
"
           "<d4p1:OperationTypeId i:nil="true" />
"
           "<d4p1:OrganizationId>%@</d4p1:OrganizationId>
"
           "<d4p1:OtherActivityId i:nil="true" />
"
           "%@
"
           "</objEventsContent>
"
           "<ismobile>true</ismobile>
"
           "</InsUpdDelActivityInfo>
"
           "</s:Body>
"
           "</s:Envelope>", statusText, [appDelegateObj.loginUserInfoDict valueForKey:@"a:UserId"], [appDelegateObj.loginUserInfoDict valueForKey:@"a:OrgId"], workspaceStr];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@iCampusliteMobileService/ActivityStreamSl.svc", appDelegateObj.baseURL]]];
NSString *messageLength = [NSString stringWithFormat:@"%lu", (unsigned long)[postStr length]];
[request addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[request addValue:@"http://tempuri.org/IActivityStreamSl/InsUpdDelActivityInfo" forHTTPHeaderField:@"SOAPAction"];
[request addValue:messageLength forHTTPHeaderField:@"Content-Length"];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:[postStr dataUsingEncoding:NSUTF8StringEncoding]];
NSError *error = nil;
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:&error];

在上面的请求中有一个元素 ActivityStreamImagesBytes 这是我必须传递图像的 base64binary 参数.

in the above request there is an element ActivityStreamImagesBytes which is base64binary parameter i have to pass the image.

我尝试过使用许多不同的格式.

I've tried using many different formats.

这是 wcf 服务截图

here is wcf service screenshot

这里是服务器端代码

public string byteArrayToImage(byte[] byteArrayIn,string fileName)
    {
        if (byteArrayIn != null)
        {
            ActivityStreamSl.LogMsg("Byte Array Count : "+byteArrayIn.Length.ToString(), "D:\log.txt");
            var serverfile = "D:somepathsomepathsomefolder";
            var getfile = HelperClass.Filesavehelper(Constants.UploadPaths.ActivityStream, "testfilename.png", serverfile);

            FileStream file = new FileStream(getfile, FileMode.Create);
            file.Write(byteArrayIn, 0, byteArrayIn.Length);
            file.Close();
            file.Dispose();
            return getfile;
        }
        else
        {
            ActivityStreamSl.LogMsg("Byte array is null","D:\log.txt");
        }
        return "";
    }

服务器需要一个字节数组，但我不知道如何发送它?我不知道 base64binary 数据类型是什么?我是否必须从 NSData *data = UIImageJPEGRepresentation([UIImage imageNamed:@"popular.png"], 0.7);

the server is expecting a byte array and i dont know how to send it? And i dont know what a base64binary data type is? Do I have to send the base64 encoded string or byte array or just data of image from NSData *data = UIImageJPEGRepresentation([UIImage imageNamed:@"popular.png"], 0.7);

任何帮助都是可观的

推荐答案

Hiii,我有我的问题

Hiii, I've got what my problem is

在服务器端，它需要一个字节数组，

On server side, its expecting a byte array,

所以，我必须按如下方式发送我的请求.

So, I've to send my request as follows.

将base64字符串转成字节数组

Converting the base64 string into byte array

我托管了这些服务，并且看到了请求的 xml 格式.无论如何，谢谢@Duraiamuthan.H

I've hosted the services and there i've seen the xml format of the request. Any way thank you @Duraiamuthan.H
