Question

我正在使用AFNetworking 2.0，在这里我必须在身体部分传递json对象，如何在AFHTTPRequestOperationManager中传递HTTP Body。

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = @{@"foo": @"bar"};
NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];
[manager POST:@"http://example.com/resources.json" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    [formData appendPartWithFileURL:filePath name:@"image" error:nil];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Success: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

谢谢，

离线聊天，听起来主要关注的是如何在单个请求中发送个人资料图片，姓名，电子邮件地址，用户ID和密码。它可能看起来像：

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSURL *filePath = ...
[manager POST:@"http://example.com/registration.json" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    [formData appendPartWithFileURL:filePath name:@"image" error:nil];
    [formData appendPartWithFormData:[name dataUsingEncoding:NSUTF8StringEncoding] name:@"name"];
    [formData appendPartWithFormData:[email dataUsingEncoding:NSUTF8StringEncoding] name:@"email"];
    [formData appendPartWithFormData:[userid dataUsingEncoding:NSUTF8StringEncoding] name:@"userid"];
    [formData appendPartWithFormData:[password dataUsingEncoding:NSUTF8StringEncoding] name:@"password"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Success: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

不需要JSON。

如果您想使用JSON，可以这样做，但不会使用constructingBodyWithBlock方法（创建multipart/form-data请求）。相反，您只需创建一个普通的旧JSON请求，例如：

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

NSDictionary *parameters = @{
    @"name"     : name,
    @"email"    : email,
    @"userid"   : userid,
    @"password" : password,
    @"image"    : base64EncodedImage
};

[manager POST:@"http://example.com/registration.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Success: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

显然，这些是非常不同的方法，因此无论采用何种方法，都需要编写服务器代码来处理相同的API。
