这问题困扰我好长时间,不上传文件就不是乱码,传文件就乱码,并且Android好使;
最后联合中间件后台/Android客户端/IOS客户端,共同上传比较,
最后在后台捕捉时发现,Android的提交输出格式为:

IOS的提交输出格式为:

发现post的Value都是中文的,都没有经过编码, 不过Android的设置了Content-Type,而IOS的ASIHttpRequest中,上传文件时忽略了Content-Type的头注入,导致后台不识别编码模式, 不过应该是后台特意对Android做过些处理, (之前Android传文件是乱码).现在问题解决了!!

下面是代码修改处:


在ASIFormDataRequest 中的 - (void)buildMultipartFormDataPostBody 方法修改

高亮处为修改代码:

- (void)buildMultipartFormDataPostBody {#if DEBUG_FORM_DATA_REQUEST[self addToDebugBody:@"\r\n==== Building a multipart/form-data body ====\r\n"];#endifNSString *charset = (NSString *)CFStringConvertEncodingToIANACharSetName(CFStringConvertNSStringEncodingToEncoding([selfstringEncoding]));// We don't bother to check if post data contains the boundary, since it's pretty unlikely that it does.CFUUIDRef uuid =CFUUIDCreate(nil);NSString *uuidString = [(NSString*)CFUUIDCreateString(nil, uuid)autorelease];CFRelease(uuid);NSString *stringBoundary = [NSStringstringWithFormat:@"0xKhTmLbOuNdArY-%@",uuidString];[selfaddRequestHeader:@"Content-Type"value:[NSStringstringWithFormat:@"multipart/form-data; charset=%@; boundary=%@", charset, stringBoundary]]; [selfappendPostString:[NSStringstringWithFormat:@"--%@\r\n",stringBoundary]];// Adds post dataNSString *endItemBoundary = [NSStringstringWithFormat:@"\r\n--%@\r\n",stringBoundary];NSUInteger i=0;for (NSDictionary *valin [selfpostData]) { [selfappendPostString:[NSStringstringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\nContent-Type:text/plain; charset=UTF-8\r\n\r\n",[valobjectForKey:@"key"]]]; [selfappendPostString:[valobjectForKey:@"value"]]; i++;if (i != [[selfpostData]count] || [[selffileData]count] >0) {//Only add the boundary if this is not the last item in the post body [selfappendPostString:endItemBoundary]; } }// Adds files to upload i=0;for (NSDictionary *valin [selffileData]) { [selfappendPostString:[NSStringstringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"%@\"\r\n", [valobjectForKey:@"key"], [valobjectForKey:@"fileName"]]]; [selfappendPostString:[NSStringstringWithFormat:@"Content-Type: %@\r\n\r\n", [valobjectForKey:@"contentType"]]];id data = [valobjectForKey:@"data"];if ([dataisKindOfClass:[NSStringclass]]) { [selfappendPostDataFromFile:data]; }else { [selfappendPostData:data]; } i++;// Only add the boundary if this is not the last item in the post bodyif (i != [[selffileData]count]) { [selfappendPostString:endItemBoundary]; } } [selfappendPostString:[NSStringstringWithFormat:@"\r\n--%@--\r\n",stringBoundary]];#if DEBUG_FORM_DATA_REQUEST[self addToDebugBody:@"==== End of multipart/form-data body ====\r\n"];#endif}

**** 51cto  .富文本代码语言竟然没有ObjC的????   这也太low了吧?  .算了 凑合看吧!!!!
