iOS通过http post上传图片
本文实例为大家分享了iOS通过httppost上传图片的相关代码，供大家参考，具体内容如下
//ASIFormDataRequest方式POST上传图片
-(NSDictionary*)addPicWithDictionary:(NSDictionary*)sugestDic{
NSDictionary*tempDic=nil;
NSString*url=[NSStringstringWithFormat:@"http://182.50.0.62:8095/xianServer/upload/uploadImage?clientType=mobile"];
form=[[[ASIFormDataRequestalloc]
initWithURL:[NSURLURLWithString:url]]autorelease];
[formsetTimeOutSeconds:60.0];
form.delegate=self;
//添加拍照图
//分界线的标识符
NSString*TWITTERFON_FORM_BOUNDARY=@"AaB03x";
//分界线--AaB03x
NSString*MPboundary=[[NSStringalloc]initWithFormat:@"--%@",TWITTERFON_FORM_BOUNDARY];
//结束符AaB03x--
NSString*endMPboundary=[[NSStringalloc]initWithFormat:@"%@--",MPboundary];
//添加拍照图片
imageView.image=[UIImageimageNamed:@"btn_done_down@2x.png"];
NSData*data=UIImagePNGRepresentation(imageView.image);
NSLog(@"%@",data);
//httpbody的字符串
NSMutableString*body=[[NSMutableStringalloc]init];
//参数的集合的所有key的集合
NSArray*keys=[sugestDicallKeys];
//遍历keys
for(inti=0;i<[keyscount];i++)
{
//得到当前key
NSString*key=[keysobjectAtIndex:i];
//如果key不是pic，说明value是字符类型，比如name：Boris
if(![keyisEqualToString:@"files"])
{
//添加分界线，换行
[bodyappendFormat:@"%@\r\n",MPboundary];
//添加字段名称，换2行
[bodyappendFormat:@"Content-Disposition:form-data;name=\"%@\"\r\n\r\n",key];
//添加字段的值
[bodyappendFormat:@"%@\r\n",[sugestDicobjectForKey:key]];
}
}
if(imageView.image){
////添加分界线，换行
[bodyappendFormat:@"%@\r\n",MPboundary];
//声明pic字段，文件名为boris.png
[bodyappendFormat:@"Content-Disposition:form-data;name=\"files\";filename=\"boris.png\"\r\n"];
//声明上传文件的格式
[bodyappendFormat:@"Content-Type:image/png\r\n\r\n"];
}
//声明结束符：--AaB03x--
NSString*end=[[NSStringalloc]initWithFormat:@"\r\n%@",endMPboundary];
//声明myRequestData，用来放入httpbody
NSMutableData*myRequestData=[NSMutableDatadata];
//将body字符串转化为UTF8格式的二进制
[myRequestDataappendData:[bodydataUsingEncoding:NSUTF8StringEncoding]];
//将image的data加入
[myRequestDataappendData:data];
//加入结束符--AaB03x--
[myRequestDataappendData:[enddataUsingEncoding:NSUTF8StringEncoding]];
//设置HTTPHeader中Content-Type的值
NSString*content=[[NSStringalloc]initWithFormat:@"multipart/form-data;boundary=%@",TWITTERFON_FORM_BOUNDARY];
[formaddRequestHeader:@"Content-Type"value:content];
[formaddRequestHeader:@"Content-Length"value:[NSStringstringWithFormat:@"%d",[myRequestDatalength]]];
[formsetRequestMethod:@"POST"];
[formstartAsynchronous];
[formsetDidFailSelector:@selector(requestBeFailed:)];
[formsetDidFinishSelector:@selector(requestBeFinished:)];
//解析取得的结果
returntempDic;
}
