使用带有空参数的 AFNetworking 上传图像不起作用

Question

我也想将图片上传到服务器，但上传时出错

我使用了以下代码，但不知道其中有什么问题

+(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];
}

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

不知道是我做错了还是服务器做错了

请尝试以下代码。希望它对你有用。

    NSData *tempData = [NSData dataWithContentsOfFile:YOUR_IMAGE_FILE_PATH];

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.requestSerializer = [AFJSONRequestSerializer serializer];

    [manager POST:YOUR_REQUEST_URL parameters:YOUR_PARAMETERS constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        if (tempData) {
            [formData appendPartWithFileData:tempData name:@"user_image" fileName:@"avatar.jpeg" mimeType:@"image/jpeg"];
        }
    } success:^(AFHTTPRequestOperation *operation, id responseObject){
        NSError *error;
        NSDictionary* json = [NSJSONSerialization
                              JSONObjectWithData:operation.responseData
                              options:kNilOptions
                              error:&error];
        NSLog(@"Registration JSON:- %@",json);
    }failure:^(AFHTTPRequestOperation *operation, NSError *error){
        NSLog(@"Error: %@", error);
    }];

“user_image”是图像的关键参数。此密钥在 API 请求参数中设置。

谢谢:)

添加您的 URL 最后一个组件名称并更改您的代码，如下所示：

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];
