AFNetWorking 文件上传 By-H罗

一.文件上传（图片，音频，视频，文本等）（不带进度）

/**
 *  文件上传  导入 #import "AFNetworking.h"
 *  @param filePath 上传文件本地路径
 */
-(void)uploadfile:(NSString *)filePath
{
    //服务器所需参数（根据服务器需要设置）
    NSMutableDictionary *params=[NSMutableDictionary dictionary];
    [params setObject:@"0" forKey:@"uptype"];         //0-表单上传  1-字节流上传
    [params setObject:@"VEJQemdPdDd6ZEdhYWY1" forKey:@"key"];

    NSData   *fileData=[NSData dataWithContentsOfFile:filePath];  //二进制数据
    NSString *fileName=[filePath lastPathComponent];              //文件名
    NSString *mimeType=[self getMIMEType:filePath];               //文件类型

    if (!mimeType) {
        mimeType = @"application/octet-stream";                   //不知道文件类型
    }
    AFHTTPRequestOperationManager *requestManager = [AFHTTPRequestOperationManager manager];
    requestManager.responseSerializer = [AFHTTPResponseSerializer serializer];//这个有时必须设置
    requestManager.requestSerializer.timeoutInterval=45.f;//请求超时45S
    [requestManager POST:@"http://218.107.2.205:8080/mage/upload/file/save?" parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        [formData appendPartWithFileData:fileData name:@"file" fileName:fileName mimeType:mimeType];
    } success:^(AFHTTPRequestOperation *operation, id responseObject) {
        //系统自带JSON解析
        NSDictionary *resultJsonDic = [NSJSONSerialization JSONObjectWithData:operation.responseData options:NSJSONReadingMutableLeaves error:nil];
      NSLog(@"上传成功resultJsonDic-%@",resultJsonDic);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {

        NSLog(@"上传失败Error-%@",error);
    }];
}

二.文件上传（带上传进度）

/**
 *  功能 AFNetWorking带进度指示文件上传
 *  @param filePath 文件路径
 */
-(void)uploadfile:(NSString *)filePath
{
    //服务器所需参数（非必须）
    NSMutableDictionary *params=[NSMutableDictionary dictionary];
    [params setObject:@"0" forKey:@"uptype"];  //0-表单上传  1-字节流上传
    [params setObject:@"VEJQemdPdDd6ZEdhYWY1" forKey:@"key"];

    NSData  *fileData=[NSData dataWithContentsOfFile:filePath];  //二进制数据
    NSString *fileName=[filePath lastPathComponent];             //文件名
    NSString *mimeType=[self getMIMEType:filePath];              //文件类型

    if (!mimeType) {
        mimeType = @"application/octet-stream";
    }

    AFHTTPRequestOperationManager *requestManager = [AFHTTPRequestOperationManager manager];
    requestManager.responseSerializer = [AFHTTPResponseSerializer serializer];
    requestManager.requestSerializer.timeoutInterval=15.f;//请求超时45S

    NSMutableURLRequest *request = [requestManager.requestSerializer multipartFormRequestWithMethod:@"POST" URLString:SBUploadFileurl parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        [formData appendPartWithFileData:fileData name:@"file" fileName:fileName mimeType:mimeType];
    } error:nil];

    AFHTTPRequestOperation *operation = [requestManager HTTPRequestOperationWithRequest:request
                                                                                success:^(AFHTTPRequestOperation *operation, id responseObject) {
                                                                                    //        //系统自带JSON解析
                                                                                    NSDictionary *resultJsonDic = [NSJSONSerialization JSONObjectWithData:operation.responseData options:NSJSONReadingMutableLeaves error:nil];
                                                                                    NSLog(@"上传成功--%@",resultJsonDic);
                                                                                } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
                                                                                    NSLog(@"失败--%@",error);
                                                                                }];

    [operation setUploadProgressBlock: ^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
        float  progress=(float)totalBytesWritten / totalBytesExpectedToWrite;
        NSLog(@"上传进度 = %f",progress);
    }];

    [request setTimeoutInterval:25.0f];
    [requestManager.operationQueue addOperation:operation];

}
