objective-c - 如何在不使用 ASIHTTPRequest 的情况下上传多张图片

Question

我想用下面的代码将两张图片上传到服务器，谁能帮帮我，这是我的发布数据代码

- (void)uploadPath:(NSString*)path withOptions:(NSDictionary*)options withImageData1:(NSData*)data1 ofImageName1:(NSString *)imageName1 andImageData2:(NSData*)data2 ofImageName2:(NSString *)imageName2 {  
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; 
    NSURL *url = [NSURL URLWithString:path relativeToURL:[NSURL URLWithString:baseURLString]];
    NSMutableURLRequest *mutableRequest = [[NSMutableURLRequest alloc] initWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:90.0];

    NSString *boundary = @"-------1234567";

    [mutableRequest setValue:[NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary] forHTTPHeaderField:@"Content-Type"];
    [mutableRequest setHTTPMethod:@"POST"];
    NSMutableData *postbody = [NSMutableData data];

    for(NSString *key in options)
    {
        NSString *value = [options objectForKey:key];
        [postbody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
        [postbody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n", key] dataUsingEncoding:NSUTF8StringEncoding]];
        [postbody appendData:[value dataUsingEncoding:NSUTF8StringEncoding]];
    }   
    [postbody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

    //*******************   Append 1st Image    ************************/

    if ([imageName1 isEqualToString:@"picture1.jpg"]) {
        [postbody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"picture1\"; filename=\"%@\"\r\n",imageName1] dataUsingEncoding:NSUTF8StringEncoding]];
    }
    [postbody appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
    [postbody appendData:[NSData dataWithData:data1]];
    [postbody appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    //*******************   Append 1st Image    ************************/

    //*******************   Append 2nd Image    ************************/   

    if ([imageName2 isEqualToString:@"picture2.jpg"]) {
        [postbody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"picture2\"; filename=\"%@\"\r\n",imageName2] dataUsingEncoding:NSUTF8StringEncoding]];
    }
    [postbody appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
    [postbody appendData:[NSData dataWithData:data2]];

    //*******************   Append 2nd Image    ************************/

        [mutableRequest setHTTPBody:postbody];
    urlConnection = [[NSURLConnection alloc] initWithRequest:mutableRequest delegate:self];
    if (self.urlConnection) {
        self.dataXml = [NSMutableData data];
    }
    self.urlConnection = nil;
    [mutableRequest release];
    [pool release];
}

查看错误的一种解决方案:

1. 创建一个新项目，使用 ASIHttpRequest
2. 获取网络调试代理，如 Charles
3. 打开 Charles(或其他)，进行成功的多文件上传。记录从 HTTP 流量到服务器的数据。
4. 现在运行您自己的代码。记录该流量。有什么不同你的流量到工作流量？让你的完全相同尊重，它怎么行不通？

您还可以将步骤 (1) 替换为 curl 命令行，该命令行将多个文件上传到服务器并记录该流量，但我对 curl 还不够熟悉> 凭空说出该命令的样子。
