【问题描述】：

我是 iPhone 编程的新手。使用下面的代码，我尝试上传多个图像和音频以及用户 ID、标题、服务器中的其他合并图像，但它不工作前 3 个参数在存储多个音频和图像之后用于循环我正在一一上传，但在内部数据没有上传到服务器中，我从服务器收到响应，比如没有上传图像和音频。谁能告诉我这段代码有什么错误。

您好，我正在使用以下代码将两个图像从我的应用程序上传到 java 服务，

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"yourServiceUrl"]];
[request setHTTPMethod:@"POST"];

NSString *boundary = [NSString stringWithFormat:@"--yourboundary"];
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];//initial boundary
[request setValue:contentType forHTTPHeaderField:@"Content-Type"];


NSMutableData *body = [NSMutableData data];

for(int i =0; i<=1;i++)
{
 [body appendData:[[NSString stringWithFormat:@"--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
 [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"%@\"\r\n",arrNames[i],arrImageNames[i]] dataUsingEncoding:NSUTF8StringEncoding]];
 [body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
 [body appendData:[NSData dataWithData:arrImgData[i]]];
 [body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
}

[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; //final boundary

[request setHTTPBody:body];
[request setValue:[NSString stringWithFormat:@"%d",[body length]]  forHTTPHeaderField:@"Content-Length"];
