其实我弄了好久，也没弄好多张一起上传，只好弄单张上传，如果你看到这篇文章对您有帮助的话欢迎您及时完善我的信息，也让我学习一下多张上传怎么弄，谢谢
//首先实例化一个AFHTTPRequestOperationManager操作对象
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:@"上传图片的接口"]];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
NSString *documentsDirectory = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"logo1.jpg"];
NSData *logoJpg = [NSData dataWithContentsOfFile:documentsDirectory];
UIImage * image = [UIImage imageWithData:logoJpg];
上面是从手机路径中取图片
// NSURL *filePath = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"avatar.jpg" ofType:nil]];
NSData *imageData = UIImageJPEGRepresentation(image, 1.0);//压缩
UIImage *image = [UIImage imageNamed:@"头像1"];
NSData *data = UIImagePNGRepresentation(image);
// 在网络开发中，上传文件时，是文件不允许被覆盖，文件重名
// 要解决此问题，
// 可以在上传时使用当前的系统事件作为文件名
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
// 设置时间格式
formatter.dateFormat = @"yyyyMMddHHmmss";
NSString *str = [formatter stringFromDate:[NSDate date]];
NSString *fileName = [NSString stringWithFormat:@"%@.png", str];
/*
此方法参数
1. 要上传的[二进制数据]
2. 对应网站上[upload.php中]处理文件的[字段"file"]
3. 要保存在服务器上的[文件名]
4. 上传文件的[mimeType]
*/
if (imageData) {
NSDictionary * dic1 = @{};//接口要求的参数
NSMutableURLRequest *request = [manager.requestSerializer
multipartFormRequestWithMethod:@"POST"
URLString:@"http://yapi.chelehuo.net/upload"
parameters:dic1
constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData
name:@"logo1"
fileName:@"logo1.jpg"
mimeType:@"image/jpeg"];
}
error:nil];
AFHTTPRequestOperation *operation = [manager HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"operation1:%@", responseObject);
弄你想要的参数
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"failure. upload....");
}];
[manager.operationQueue addOperation:operation];
//可以查看上传的进度
[operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
NSLog(@"百分比:%f",totalBytesWritten*1.0/totalBytesExpectedToWrite);
}];
}
多张图片上传的方法
方法一:
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer]multipartFormRequestWithMethod:@"POST" URLString:url parameters:url参数 constructingBodyWithBlock:^(id<AFMultipartFormData>
formData) {
for (int i = 0; i<arrayImage.count; i++) {
UIImage *uploadImage = arrayImage[i];
[formData appendPartWithFileData:UIImagePNGRepresentation(uploadImage)name:[NSString stringWithFormat:@"参数%d",i+1] fileName:@"test.jpg"mimeType:@"image/jpg"];
}
} error:nil];
AFHTTPRequestOperation *opration = [[AFHTTPRequestOperationalloc]initWithRequest:request];
opration.responseSerializer.acceptableContentTypes = [NSSetsetWithObject:@"text/html"];
[opration setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, idresponseObject) {
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
}
这个多张上传我是失败的不知道为啥
这是我在网上看到的几个博客里的例子，可以看看
