AFNetworking 2.0 multipart/form-data 上传到 mySQL

Question

我尝试了很多方法，但似乎无法正常工作。我可以通过 UITextField 将文本上传到 mySQL 数据库，我可以通过 UIImageView 分别上传图像，但是当我尝试将它们放在一起时它不起作用：

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/html",@"application/json",nil];
NSDictionary *parameters = @{@"new": self.enter};
NSData *imageData = UIImageJPEGRepresentation(self.uploadImage.image, 0.5);
[manager POST:@"http://emily-ip.com/write.php" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
            [formData appendPartWithFileData:imageData name:@"image" fileName:@"photo.jpg" mimeType:@"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Success: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

此代码给出错误：

"The operation couldn’t be completed. (Cocoa error 3840.)" (JSON text did not start with array or object and option to allow fragments not set.) UserInfo=0x7fabeb081660

所以我把这个放在：

manager.responseSerializer = [AFHTTPResponseSerializer serializer];

这会上传图片但不会上传从文本字段输入的文本，这是我得到的输出：

Success: <4572726f 72>
Success: <53756363 65737366 756c>

看了那么多帖子也没找到问题所在。无论如何，我认为它与文本字段有关。有人可以帮我修复代码吗？

我想通了。这是 post 来自文本字段和 UIImageVIew 的图像和文本：

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/html",@"application/json",nil];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
NSDictionary *parameters = @{@"new": self.enter.text};
NSData *imageData = UIImageJPEGRepresentation(self.uploadImage.image, 0.5);
[manager POST:@"http://emily-ip.com/write.php" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
            [formData appendPartWithFileData:imageData name:@"image" fileName:@"photo.jpg" mimeType:@"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Success: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];
