尝试设置执行网络请求并尝试序列化响应的单元测试。我目前收到错误：Ambiguous reference to member 'jsonObject(with:options:)'。由于单元测试应该知道JSONSerialization是什么，所以对于为什么会发生这种情况感到困惑。是
func testAccessKeys() {
let expected = expectation(description: "Run the Access request")
sut.request(.Access, data: nil) { finished, response in
if response != nil && finished == true {
guard let json = try? JSONSerialization.jsonObject(with: response!, options: .mutableContainers) as! [String:Any] else { return XCTFail("Access request was not a dictionary")}
XCTAssertNotNil(json?["id"])
expected.fulfill()
} else {
XCTFail("Access response was nil")
}
}
waitForExpectations(timeout: 3) { error in
if let error = error {
XCTFail("Access request failure: \(error)")
}
}
}
