Question

我正在尝试使用http POST和AFNetworking在其他一些字符串中发送base64编码的图像。我试图将参数作为NSDictionary发送：

  NSMutableDictionary *info = [NSMutableDictionary dictionary];
    [info setValue:filedata forKey:@"filedata"];
    [info setValue:comments forKey:@"comments"];
    [info setValue:username forKey:@"username"];
    [info setValue:@"jpg" forKey:@"filetype"];
    [info setValue:filename forKey:@"filename"];

使用AFNetworking

和POST：

AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
    manager.requestSerializer = [AFJSONRequestSerializer serializer];
    [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

    [manager POST:@"https://myurl.com/fileupload" parameters:info progress:nil success:^(NSURLSessionTask *task, id responseObject) {
        NSLog(@"JSON: %@", responseObject);
    } failure:^(NSURLSessionTask *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];

但是我不知道此时还有什么可做的。我错过了什么？谢谢

您可以使用以下示例

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

[manager POST:@"https://myurl.com/fileupload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    [formData appendPartWithFileData:imageData
                                name:@"key name for the image"
                            fileName:photoName mimeType:@"image/jpeg"];
} success:^(NSURLSessionDataTask *task, id responseObject) {
    NSLog(@"Response: %@", responseObject);
} failure:^(NSURLSessionDataTask *task, NSError *error) {
    NSLog(@"Error: %@", error);
}];

AFNetworking - 对REST进行HTTP POST，发送带有Base64string图像的JSON
