Objective c 使用AFNetworking将.zip文件上载到REST服务器失败

objective-c macos rest file-upload

Objective c 使用AFNetworking将.zip文件上载到REST服务器失败,objective-c,macos,rest,file-upload,afnetworking-2,Objective C,Macos,Rest,File Upload,Afnetworking 2,从AFNetworking文档中，我在尝试将文件上载到REST服务器时得到了以下代码，该服务器与其他客户端一起工作正常，但在我的实现中，由于内部服务器错误而崩溃代码如下： - (BOOL)uploadFile:(NSString *)path apiKey:(NSString *)apiKey { NSData *symbolsData = [NSData dataWithContentsOfFile:path]; if (!symbolsData) { NS

从AFNetworking文档中，我在尝试将文件上载到REST服务器时得到了以下代码，该服务器与其他客户端一起工作正常，但在我的实现中，由于内部服务器错误而崩溃

代码如下：

- (BOOL)uploadFile:(NSString *)path apiKey:(NSString *)apiKey
{
    NSData *symbolsData = [NSData dataWithContentsOfFile:path];

    if (!symbolsData) {
        NSLog(@"Symbols file at %@ does not exist.", path);
        return NO;
    }

    if ([symbolsData length] > 33554432) {
        NSLog(@"Symbols file at %@ is too large to upload.", path);
        return NO;
    }

    NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:[NSString stringWithFormat:@"%@/upload/thefile", BaseURL] parameters:nil constructingBodyWithBlock:
        ^(id<AFMultipartFormData> formData)
            {
            [formData appendPartWithFileData:symbolsData name:@"file" fileName:[path lastPathComponent] mimeType:@"application/zip"];
            }
        error:nil];
    [request setValue:apiKey forHTTPHeaderField:@"X-theapikey"];

    AFURLSessionManager* manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

    NSURLSessionUploadTask* uploadTask = [manager uploadTaskWithStreamedRequest:request progress:nil completionHandler:
        ^(NSURLResponse *response, id responseObject, NSError *error)
            {
            if (!error)
                {
                NSLog(@"Successfully uploade file: %@\r\nwith Response: %@", [path lastPathComponent], (NSString*)responseObject);
                }
            else
                {
                NSLog(@"There was an error while uploading the file: %@", [error description]);
                }
            }];

    [uploadTask resume];

    return YES;
}

在互联网上搜索之后，我看到了很多实现，MIME类型变为application/octet-stream和其他东西，但没有任何效果

还添加了AFNetworkActivityLogger并注册到NSNotificationCenter以检查请求：

Request: <NSMutableURLRequest: 0x600000014680> { URL: http://IP_ADDRESS:3000/upload/thefile }
2014-05-28 03:03:16.112 MyMacApp[5092:303] POST 'http://IP_ADDRESS:3000/upload/thefile': {
    "Accept-Language" = "en;q=1, ja;q=0.9, fr;q=0.8, de;q=0.7, es;q=0.6, it;q=0.5";
    "Content-Length" = 817739;
    "Content-Type" = "multipart/form-data; boundary=Boundary+E25BB25240379DA8";
    "User-Agent" = "MyMacApp/1.1 (Mac OS X Version 10.9.3 (Build 13D65))";
    "X-thapikey" = 9e301234;
} (null)

请求：{URL:http://IP_ADDRESS:3000/upload/thefile }
2014-05-28 03:03:16.112 MyMacApp[5092:303]POST'http://IP_ADDRESS:3000/upload/thefile': {
“接受语言”=“en；q=1，ja；q=0.9，fr；q=0.8，de；q=0.7，es；q=0.6，it；q=0.5”；
“内容长度”=817739；
“内容类型”=“多部分/表单数据；边界=边界+E25BB25240379DA8”；
“用户代理”=“MyMacApp/1.1（Mac OS X版本10.9.3（构建13D65））”；
“X-thapikey”=9e301234；
}（空）

我可以看到内容类型看起来不错，并且有一个内容长度

编辑： 引发服务器异常：

如何调试并找出我的请求失败的原因

服务器接受文件，并使用其他客户端、POSTman、Cocoa REST客户端对其进行测试

谢谢。

通过删除AFNetworking并使用Apple的NSURLRequest、NSURLConnection类以及stackoverflow中的一些搜索找到了答案

我应该提到的是，这可能是服务器不支持AFNetworking请求，或者请求不能与所有服务器一起工作

我的工作代码：

- (NSMutableURLRequest *)buildRequest:(NSData *)paramData fileName:(NSString *)name
    {
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
    [request setURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@/upload/thefile", BaseURL]]];
    [request setHTTPMethod:@"POST"];

    NSString *boundary = @"0xKhTmLbOuNdArY";
    NSString *endBoundary = [NSString stringWithFormat:@"\r\n--%@--", boundary];

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

    NSMutableData *tempPostData = [NSMutableData data]; 
    [tempPostData appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];

    // Sample file to send as data
    [tempPostData appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"file\"; filename=\"%@\"\r\n", name] dataUsingEncoding:NSUTF8StringEncoding]];
    [tempPostData appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
    [tempPostData appendData:paramData];
    [tempPostData appendData:[endBoundary dataUsingEncoding:NSUTF8StringEncoding]];
    [request setHTTPBody:tempPostData];

    return request;
    }
