Question

此问题可能与AFNetworking无关，但在构建NSURLRequest时更多。我正在尝试使用AFNetworking-

发出下降的GET请求

curl -X GET \
  -H "X-Parse-Application-Id: Q82knolRSmsGKKNK13WCvISIReVVoR3yFP3qTF1J" \
  -H "X-Parse-REST-API-Key: iHiN4Hlw835d7aig6vtcTNhPOkNyJpjpvAL2aSoL" \
  -G \
  --data-urlencode 'where={"playerName":"Sean Plott","cheatMode":false}' \
  https://api.parse.com/1/classes/GameScore

这是来自parse.com API https://parse.com/docs/rest#queries-constraints。

但是，我无法弄清楚如何写

[AFHTTPClient getPath：parameters：success：failure：]

此请求。 where子句看起来不像字典，但是这个函数只为其参数输入获取字典。

参数需要NSDictionary，它将在URL中转换为键/值对。因此关键很容易，但在将其设置为字典之前，您需要将其转换为JSON ...

NSDictionary *jsonDictionary = [[NSDictionary alloc] initWithObjectsAndKeys:
                                @"Sean Plott", @"playerName",
                                [NSNumber numberWithBool:NO], @"cheatMode", nil];

NSError *error = nil;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:jsonDictionary options:0 error:&error];

if (!jsonData) {
    NSLog(@"NSJSONSerialization failed %@", error);
}

NSString *json = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

NSDictionary *parameters = [[NSDictionary alloc] initWithObjectsAndKeys:
                            json, @"where", nil];

如果我们假设你的客户端配置了这样的东西（通常你是子类AFHTTPClient并且可以移动这些东西

AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:@"https://api.parse.com/"]];
[client setDefaultHeader:@"X-Parse-Application-Id" value:@"Q82knolRSmsGKKNK13WCvISIReVVoR3yFP3qTF1J"];
[client setDefaultHeader:@"X-Parse-REST-API-Key" value:@"iHiN4Hlw835d7aig6vtcTNhPOkNyJpjpvAL2aSoL"];
[client registerHTTPOperationClass:[AFJSONRequestOperation class]];

然后你应该可以打电话了

[client getPath:@"1/classes/GameScore"
     parameters:parameters 
        success:^(AFHTTPRequestOperation *operation, id responseObject) {
            NSLog(@"Success %@", responseObject);
        } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
            NSLog(@"Failed %@", error);
        }];

将cURL请求（使用--data-urlencode）转换为AFNetworking GET请求
