Question

我正在尝试将Wufoo API集成到iPhone应用程序中，并在最后阶段遇到困难。我已经使用AFNetworking成功连接到Wufoo表单，创建了AFHTTPClient的子类以容纳所需的额外标头，例如HTTP授权。我还将参数编码设置为AFJSONParameterEncoding。

当我使用上面的请求发出请求时，它成功连接到服务器并发布数据，但是错误与空白字段有关。我在NSDictionary中添加了字段/密钥对以在请求中传递，但它们必须是错误的格式或其他东西，因为它们没有在另一端处理。对不起，我知道这是一个冗长的问题，但任何帮助将不胜感激:)。我已经在控制台中添加了响应，以及相关的类文件/方法。

通过更改WufooAPIClient.m类initWithBaseURL：方法中的一行来解决此问题。

此：

self.parameterEncoding = AFJSONParameterEncoding;

致：

 self.parameterEncoding = AFFormURLParameterEncoding;

Wufoo通过发送HTTP POST数据来工作，然后向您发回json或xml响应。我所做的是将发送的数据设置为JSON数据，而不是原本应该使用的Form Data。

希望能帮助任何人尝试做同样的事情：）

在Objective C中将数据发布到Wufoo表单
