Question

我想从我的应用程序发出以下请求：

AFHTTPRequestOperationManager *requestManager = [[AFHTTPRequestOperationManager alloc] init];
requestManager.responseSerializer.acceptableContentTypes = [requestManager.responseSerializer.acceptableContentTypes setByAddingObject:@"application/json"];
requestManager.requestSerializer = [AFJSONRequestSerializer serializer];
[requestManager POST:urlString parameters:aParameters constructingBodyWithBlock:nil success:^(AFHTTPRequestOperation *operation, id responseObject)
{
    NSLog(@"%@", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
    NSLog(@"error: %@", error);
}];

其中aParameters是具有以下内容的NSDictionary：

NSDictionary *urlParams = @{@"username" : anUser.userName, @"password" : anUser.password};

当我使用＆＃34; anUsername＆＃34;的用户输入从我的应用程序发出请求时和＆＃34; aPassword＆＃34;我在servlet中获取了以下日志：

--Boundary+5738A89B2C391231
Content-Disposition: form-data; name="password"

aPassword
--Boundary+5738A89B2C391231
Content-Disposition: form-data; name="username"

anUsername
--Boundary+5738A89B2C391231--

multipart/form-data; boundary=Boundary+5738A89B2C391231

我的印象是使用AFJSONRequestSerializer会以适当的格式发送我的请求，但正如日志所示，它是多部分/表单数据。解析这种请求（我在服务器端用Java解析它）真的很难（对我来说），所以我的问题是：是否有可能在我的请求正文中发送一个json？像这样：

{
    "userName" : "anUsername",
    "password" : "aPassword"
}

任何帮助都将不胜感激。

对于任何关注的人：您应该使用POST:parameters:constructingBodyWithBlock:success:failure:，而不是使用POST:parameters:success:failure:方法。前者执行多部分表单请求，而后者执行url表单编码。此外，要以JSON格式发送params，requestSerializer实例的AFHTTPRequestOperationManager属性应该是AFJSONRequestSerializer的实例（默认设置为AFHTTPRequestSerializer）浏览AFHTTPRequestOperationManager的实现文件非常有用，可以帮助我排除这个错误。

您不需要在POST请求中发送纯JSON，只需发送参数字典。以下是适用于POST请求的示例代码。

+ (void)login:(BOUser *)user responseBlock:(APIRequestResponseBlock)responseBlock {

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

    [manager.requestSerializer setValue:@"parse-application-id-removed" forHTTPHeaderField:@"X-Parse-Application-Id"];
    [manager.requestSerializer setValue:@"parse-rest-api-key-removed" forHTTPHeaderField:@"X-Parse-REST-API-Key"];
    [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
     manager.securityPolicy.allowInvalidCertificates = YES;

    NSString *URLString = [NSString stringWithFormat:@"%@login", BASE_URL_STRING];
    NSDictionary *params = @{@"email": user.username,
                             @"password": user.password};


    [manager POST:URLString parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"JSON: %@", responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
        responseBlock(nil, FALSE, error);
    }];

}

我希望它有所帮助。
