鉴于都说上传数据，那我贴我上传图片的代码：

NSString *token = [[NSUserDefaults standardUserDefaults] objectForKey:@"token"];
NSString *userstr = [NSString stringWithFormat:@"%zd",[_model.cusid integerValue]];
NSString *userid = [MSEncryptUtil encryptUseDES:userstr key:token];
// 图片
NSData *data;
if (array.count > 0) {
for(int i = 0;i< array.count;i++){
// 压缩图片
data = UIImageJPEGRepresentation([array objectAtIndex:i],1.0);
NSLog(@"压缩过的图片的文件大小 %zdKB",[data length]/1024);
// 设置参数
NSMutableDictionary *dic = [NSMutableDictionary dictionary];
[dic setValue:userid forKey:@"cusId"]; // 客户id
[dic setValue:_model.cusType forKey:@"cusType"]; // 客户类型
[dic setValue:imagType forKey:@"pictureType"]; // 图片类型
