使用带有null参数的AFNetworking上载图像不起作用 [英] Uploading image with AFNetworking with null parameter doesn't work

问题描述

我也希望将图片上传到服务器但是在执行此操作时出错

I want too upload the image to server but got error on doing that

我使用了以下代码，但不知道哪里出错了

+(void) HTTPPostImage:(NSString *) stringURL andParameter:(NSData *) imageData andSelector:(SEL) selector andTarget:(id) target{

    AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:stringURL]];
   // NSData *imageData = UIImageJPEGRepresentation(self.avatarView.image, 0.5);
    NSDictionary *parameters =NULL;
    NSString *myUUID = [[NSUUID UUID] UUIDString]; // create a UUID

    NSLog(@"myUUID%@",myUUID);


    AFHTTPRequestOperation *op = [manager POST:@"" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        [formData appendPartWithFileData:imageData name:@"public.image" fileName:@"photo.jpg" mimeType:@"image/jpeg"];
        //[formData appendPartWithFileData:imageData name:@"file" fileName:myUUID mimeType:@"image/jpeg"];

    } success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"Success: %@ ***** %@", operation.responseString, responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@ ***** %@", operation.responseString, error);
    }];
    [op start];
}

我不知道这个参数有什么问题

[formData appendPartWithFileData:imageData name:@"public.image" fileName:@"photo.jpg" mimeType:@"image/jpeg"];

服务器参数

我不知道我是否犯过错误或服务器已经完成了错误

I don't know whether i have done mistakes or server has done it

推荐答案

添加您的URL最后一个组件名称并更改您的代码如下：

Add your URL last component name and change your code like this:

AFHTTPRequestOperation *op = [manager POST:@"suburl.php" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        [formData appendPartWithFileData:imageData name:@"userfile" fileName:@"photo.jpg" mimeType:@"image/jpeg"];
        //[formData appendPartWithFileData:imageData name:@"file" fileName:myUUID mimeType:@"image/jpeg"];

AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:@"http://yourbaseurl.com/"]];
// NSData *imageData = UIImageJPEGRepresentation(self.avatarView.image, 0.5);
NSDictionary *parameters =NULL;
NSString *myUUID = [[NSUUID UUID] UUIDString]; // create a UUID

NSLog(@"myUUID%@",myUUID);


AFHTTPRequestOperation *op = [manager POST:@"suburl.php" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    [formData appendPartWithFileData:imageData name:@"userfile" fileName:@"photo.jpg" mimeType:@"image/jpeg"];
    //[formData appendPartWithFileData:imageData name:@"file" fileName:myUUID mimeType:@"image/jpeg"];

} success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Success: %@ ***** %@", operation.responseString, responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@ ***** %@", operation.responseString, error);
}];
[op start];
