AFNetworking 3.0携带参数上传文件Demo

一、服务端代码：

服务端是java用国产nutz搞的，实际mvc框架都大同小异，就是提交文件的同时还带了个表单参数

@AdaptBy(type=UploadAdaptor.class, args={"${app.root}/WEB-INF/tmp/user_avatar", "8192", "utf-8", "20000", "102400"})
@At
@Aop("redis")
public Object uploadAvatar(@Param("file")TempFile tf, @Param("token") String token, AdaptorErrorContext err) {

// token 对应客户端参数名
NutMap re = new NutMap();
if (err != null && err.getAdaptorErr() != null) {
return re.setv("code", 3).setv("msg", "文件大小不符合规定");
}
if (tf == null) {
return re.setv("code", 4).setv("msg", "空文件");
}

if (Strings.isBlank(token)) {
return re.setv("code", 2).setv("msg", "");// 没有token
}
String member_id = jedis().get(token);// 从redis根据token获取member_id
if (Strings.isBlank(member_id)) {
return re.setv("code", 2).setv("msg", "");// 未登录
}
File f = tf.getFile(); // 这个是保存的临时文件
FieldMeta meta = tf.getMeta(); // 这个原本的文件信息
String oldName = meta.getFileLocalName(); // 这个时原本的文件名称

PropertiesProxy property = new PropertiesProxy("/custom/my.properties");

String filename = System.currentTimeMillis() + oldName.substring(oldName.lastIndexOf("."));
StringBuffer sb =new StringBuffer(property.get("my.filepath"));
sb.append("\\avator\\");
sb.append(filename);

StringBuffer sbdb =new StringBuffer("/avator/");
sbdb.append(filename);

try {
Files.move(f, new File(sb.toString()));
//更新数据库
dao.update(Member.class,Chain.make("avator", sbdb.toString()),Cnd.where("member_id", "=", member_id));

} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return re.setv("code", 1);
}

return re.setv("code", 0).setv("msg", "");
}

二、客户端代码：
用html表单提交的话，一般是这样的
<form action="${base}/usr/uploadAvatar" method="post"
enctype="multipart/form-data">
头像文件 <input type="file" name="file">
<p />
<div>
token:<input name="token" >
</div>
<p />
<button type="submit">更新头像</button>
</form>

IOS搞的话，这边用的是AFNetworking 3.0，所以是这样写的
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
NSLog(@"图片选中");
//截取图片
UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];
NSData *imageData = UIImageJPEGRepresentation(image, 0.001);
self.mv.portraitImageView.image = image;

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/html",@"text/plain", nil];
// 参数
NSMutableDictionary *parameter = [NSMutableDictionary dictionary];
parameter[@"token"] = "param....";
// 访问路径
NSString *stringURL = [NSString stringWithFormat:@"%@%@",HOSTURL,kUploadAvatar];

[manager POST:stringURL parameters:parameter constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
// 上传文件
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
formatter.dateFormat = @"yyyyMMddHHmmss";
NSString *str = [formatter stringFromDate:[NSDate date]];
NSString *fileName = [NSString stringWithFormat:@"%@.jpg", str];

[formData appendPartWithFileData:imageData name:@"file" fileName:fileName mimeType:@"image/png"];

} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"上传成功");
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"上传错误");
}];
}
