采用AFNetWorking 上传base64的图片到服务器，上传的图片解析不了。ASIHttpRequest上传是可以的，两种写法如下，求教，能给个思路吗？

IOS AFNetworking upload pictures to the server.The request is successful,But it can not parse base64 image.Then same request using ASIHTTPReuqest framework upload base64 images on the server side can parse is successful.Can you give a suggestion or idea？

AFNworking request Code:

UIImage *img = [avatar imageWithImageSimple:avatar scaledToSize:EZSIZE(320, 320)];

NSData* imageData = UIImageJPEGRepresentation(img, 0.5);

NSString *strBase64 = [imageData base64String];

NSDictionary * object = @{
@"firstname" :@"nameTest",
@"sex" :@"male",
@"user_id" :@"1234556",
@"avatar" :strBase64,
@"phone" :@"15899402939"
};
NSMutableDictionary *parameter = [[NSMutableDictionary alloc] init];

[parameter setObject:@1 forKey:@"app"];

[parameter setObject:@"save_settings" forKey:@"m_action"];

[parameter setObject:[[object JSONRepresentation] forKey:@"m_param"]];

NSURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST"
URLString:@"http://test..."
parameters:parameter
constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
} error:nil];



AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];

[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

}];

ASIHttpRequest request code:

UIImage *img = [avatar imageWithImageSimple:avatar scaledToSize:EZSIZE(320, 320)];
NSData* imageData = UIImageJPEGRepresentation(img, 0.5);
NSString *strBase64 = [imageData base64String];

NSDictionary * object = @{
@"firstname" :@"nameTest",
@"sex" :@"male",
@"user_id" :@"1234556",
@"avatar" :strBase64,
@"phone" :@"15899402939"
};

NSString *parameter = @"app=1";

parameter = [[parameter stringByAppendingString:@"&m_action="] stringByAppendingString:@"save_settings"];

parameter = [[parameter stringByAppendingString:@"&m_param="] stringByAppendingString:[object JSONRepresentation]];

NSData *data = [parameter dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];

[request setDidFailSelector:@selector(handleRequestEventError:)];
[request setDidFinishSelector:@selector(parseAndSave:)];

[request addRequestHeader:@"Content-Length" value:[@([data length]) stringValue]];
[request setRequestMethod:@"POST"];
[request appendPostData:data];
[request addRequestHeader:@"Content-Type" value:@"application/x-www-form-urlencoded"];

[request setDelegate:self];


[_networkQueue addOperation:request];

stackoverflow 也是我发的。。github 中 AFNetwoking 提的问题中，我也发过。

[LmyangBK]

真没办法，找不到解决的问题。

[不担心]

如果base64解析不了的话你可以直接传图片上去让服务器端处理啊,我直接贴上我传图片的代码,base64的我也有用过,没什么问题啊 +(AFHTTPRequestOperation *)updateCover:(short)coverIndex imgCover:(UIImage *)imgCover aBlock:(resultBlock)aBlock; { NSDictionary *param=@{@"token":[publicTools getIdToken], @"id":[@([currUser shareInstance].userID) stringValue], @"action":@"updatestorycover", @"cover_index":[@(coverIndex) stringValue] }; return [[netEngine uploadEngine] POST:XXX parameters:param constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { [formData appendPartWithFileData:UIImageJPEGRepresentation(imgCover, .5) name:@"uploadimg" fileName:@"asdf.jpeg" mimeType:@"image/jpeg"]; } success:^(AFHTTPRequestOperation *operation, id responseObject) { aBlock((NSDictionary *)responseObject, [[(NSDictionary *)responseObject valueForKey:@"success"] intValue], [(NSDictionary *)responseObject valueForKey:@"data"], [(NSDictionary *)responseObject valueForKey:@"message"] ); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { [self processError:error aBlock:aBlock]; }]; }

[Bannings]

你把AFNetworking和ASI对同一图片的base64分别发出来，我试试能不能解析

[Bannings]

你居然把stackoverflow上的帖子直接copy过来 太不仗义了

[LmyangBK]

- (void)testDicty { NSDictionary *dic = @{@"name1" :@"3432", @"name1" :@"3432", @"name1" :@"3432" }; NSDictionary *dicy = @{@"name" :@"zhangsan", @"age" :@"12", @"param" : [dic JSONRepresentation] }; NSLog(@"dicy = %@",dicy); } 打印输出： 2015-03-19 10:39:51.265 SD4iPad[1926:54805] dicy = { age = 12; name = zhangsan; param = "{\"name1\":\"3432\"}"; } 是不是因为当一个字典里包含有一个[dic JSONRepresentation]对象，然后dic里的Json数据就会有转义字符？ 是不是这个照成的？求解。

引用 7 楼 LmyangBK 的回复:

- (void)testDicty { NSDictionary *dic = @{@"name1" :@"3432", @"name1" :@"3432", @"name1" :@"3432" }; NSDictionary *dicy = @{@"name" :@"zhangsan", @"age" :@"12", @"param" : [dic JSONRepresentation] }; NSLog(@"dicy = %@",dicy); } 打印输出： 2015-03-19 10:39:51.265 SD4iPad[1926:54805] dicy = { age = 12; name = zhangsan; param = "{\"name1\":\"3432\"}"; } 是不是因为当一个字典里包含有一个[dic JSONRepresentation]对象，然后dic里的Json数据就会有转义字符？ 是不是这个照成的？求解。

这样有影响，如果json里套json的话，服务器拿到param后，实际上拿到的是一个字符串，需要再次把这个字符串解析为json

[Juejue]

楼主，你的问题解决了吗？我也是把图片转换为nsdata再用base64编码上传，但是服务器无法解析。而且我再上传前还做了不转义NSString *encodedString = (NSString *) CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (CFStringRef)self, (CFStringRef)@"!$&'()*+,-./:;=?@_~%#[]", NULL, kCFStringEncodingUTF8)); 好纠结啊。

[wwwang89123]

[JarvanSun]

base64编码后的字符串中含有 / ，在转JSON 的时候，iOS在/ 前添加了反斜线 \ 去AFN里的AFURLRequestSerialization 里的 - (NSURLRequest *)requestBySerializingRequest:(NSURLRequest *)request withParameters:(id)parameters error:(NSError *__autoreleasing *)error; 这个函数里跟一下看看是不是这个原因

[kongrenxin]

兄台，这个问题解决了吗？ 怎么解决的呢，我现在也碰到这个问题了。。。 需要post的body数据为 ： {"type":1,"content":"abc/ada"} 结果服务器接收到的却是：{"type":1,"content":"abc\/ada"} 多出来一个转义符 \ 怎么样才能让AFN不修改body数据呢？?
