我试图将 Zipfile 和一些参数发布到 Web 服务，但我得到响应“缺少电子书文件”，所以如何在 Objectivec 中发布 zip 文件和参数请帮助我

提前致谢

我试过这个：

      NSString *urlString1 = [NSString stringWithFormat:@"http://www.EbookFile.com/index.php?q=api/upload&APPkey=dfsfwerwe324342323432"];



    NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
                [request setURL:[NSURL URLWithString:urlString1]];
                [request setHTTPMethod:@"POST"];

                    NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];
                    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
                    [request addValue:contentType forHTTPHeaderField: @"Content-Type"];
                    NSMutableData *body = [NSMutableData data];

                // Parameter 1

                [body appendData:[[NSString stringWithFormat:@"--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
                [body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"uid\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
                [body appendData:[uid dataUsingEncoding:NSUTF8StringEncoding]];
                [body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];


                        // Parameter 2

                [body appendData:[[NSString stringWithFormat:@"--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
                [body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"title\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
                [body appendData:[titleText.text dataUsingEncoding:NSUTF8StringEncoding]];
                [body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];

                // Parameter 3


                [body appendData:[[NSString stringWithFormat:@"--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
                [body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"token\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
                [body appendData:[token dataUsingEncoding:NSUTF8StringEncoding]];
                [body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];

                // Parameter 4


                [body appendData:[[NSString stringWithFormat:@"--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
                [body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"desc\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
                [body appendData:[descText.text dataUsingEncoding:NSUTF8StringEncoding]];
                [body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];

                // Parameter 5


                [body appendData:[[NSString stringWithFormat:@"--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
                [body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"cat\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
                [body appendData:[CatId dataUsingEncoding:NSUTF8StringEncoding]];
                [body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];


        // ZIP File Post here

                int r = arc4random() % 8000000;
                NSString *RandomNumber = [NSString stringWithFormat:@"%d",r];
                NSString *file = [RandomNumber stringByAppendingString:@".zip"];

                NSData *Filedata = [NSData dataWithContentsOfURL:[NSURL fileURLWithPath:archivePath]]; // ZIP file convert to NAData here

                [body appendData:[[NSString stringWithFormat:@"Content-Disposition: attachment; name=\"file\"; filename=\"%@\"\r\n",file] dataUsingEncoding:NSUTF8StringEncoding]];
                [body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
                [body appendData:Filedata];
                [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
                [request setHTTPBody:body];

                // pointers to some necessary objects
                NSHTTPURLResponse* response =[[NSHTTPURLResponse alloc] init];
                NSError* error = [[NSError alloc] init] ;

                // synchronous filling of data from HTTP POST response
                NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

                if (error)
                {
                }

 NSString *responseString = [[[NSString alloc] initWithBytes:[responseData bytes]
                                                                     length:[responseData length]
                                                                   encoding:NSUTF8StringEncoding] autorelease];

尝试以这种方式发送文件您的文件

    NSUInteger length = [myData length];
    NSData *filedata;
         Byte *byteData = (Byte *)malloc(length);
        [data getBytes:byteData length:length];


       [postbody appendBytes:(const void *)byteData length:length];

首先，有不同风格的 Web 服务，而且您还没有指定要处理的内容。它是基于 SOAP 的服务吗？休息？XML-RPC？为了便于讨论，我假设它是一个 RESTful 服务，因为现在大多数人似乎都会去那里。

我看到的问题是您试图将参数放在帖子的正文中。您必须检查您正在使用的特定 API 的文档，但通常参数是作为您发布到的 URL 中的查询参数提供的，或者在您在请求中发送的标头中指定。请求的正文应该是压缩数据。
