iOS使用AFNetworking上传图片或者文件

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

manager.responseSerializer= [AFHTTPResponseSerializer serializer];

[manager POST:url parameters:params constructingBodyWithBlock:^(id formData) {

NSData *data =UIImageJPEGRepresentation(image,0.5);//把要上传的图片转成NSData

//把要上传的文件转成NSData

//NSString*path=[[NSBundlemainBundle]pathForResource:@"123"ofType:@"txt"];

//NSData*fileData = [NSDatadataWithContentsOfFile:path];

[formData appendPartWithFileData:dataname:@"uploadFile" fileName:@"图片1" mimeType:@"image/png"];//给定数据流的数据名，文件名，文件类型（以图片为例）

/*常用数据流类型：

@"image/png" 图片

@“video/quicktime” 视频流

*/

}success:^(AFHTTPRequestOperation*operation,id responseObject) {

//NSLog(@"%@",responseObject);//返回结果

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

//NSLog(@"%@",error.localizedDescription);//请求失败结果

}];
