Question

我正在使用AFNetworking 2.0和OHHTTPStubs编写单元测试用例，测试总是因这些错误而失败：

响应错误：无法完成操作。（可可错误3840.）。

非常感谢！

下面是简单测试Json（User.json）： { “userId”：“abc”， “email”：“ab @ pant.com”， “username”：“usera” }

和测试用例代码：

- (void)testGet
{
    [OHHTTPStubs stubRequestsPassingTest:^BOOL(NSURLRequest *request) {
        return YES; // Stub ALL requests without any condition
    } withStubResponse:^OHHTTPStubsResponse*(NSURLRequest *request) {
        return [OHHTTPStubsResponse responseWithFileAtPath:OHPathForFileInBundle(@"User.json",nil)
            statusCode:200 headers:@{@"Content-Type":@"application/json"}];
    }];

    dispatch_semaphore_t semaphore = dispatch_semaphore_create(0);

    AFHTTPSessionManager* requestManager = [[AFHTTPSessionManager alloc]initWithBaseURL:[NSURL URLWithString:@"http://test.com"]];
    AFJSONResponseSerializer* responseSerializer = [[[AFJSONResponseSerializer alloc]init] autorelease];
    responseSerializer.readingOptions = NSJSONReadingAllowFragments;
    responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
    responseSerializer.acceptableStatusCodes = [NSIndexSet indexSetWithIndexesInRange:NSMakeRange(200, 2)];
    requestManager.responseSerializer = responseSerializer;

    AFJSONRequestSerializer* requestSerializer = [[AFJSONRequestSerializer alloc] init];
    requestSerializer.writingOptions = NSJSONWritingPrettyPrinted;
    [requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];

    requestManager.requestSerializer = requestSerializer;

    _done = NO;
    [requestManager GET:@"stream" parameters:nil success:^(NSURLSessionDataTask * task, id JSON)
    {
        NSLog(@"Response data:%@", JSON);
        XCTAssert(JSON != nil, @"null response");
        dispatch_semaphore_signal(semaphore);

    } failure:^(NSURLSessionDataTask *__unused task, NSError *error) {
        NSLog(@"Response error:%@", [error localizedDescription]);
        XCTFail(@"fail to get response");
        dispatch_semaphore_signal(semaphore);
    }];

    while (dispatch_semaphore_wait(semaphore, DISPATCH_TIME_NOW))
    {
        [[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode
                                 beforeDate:[NSDate dateWithTimeIntervalSinceNow:10]];
    }
}

尝试使用AFHTTPResponseSerializer代替。所以基本上，替换这段代码：

    AFJSONResponseSerializer* responseSerializer = [[[AFJSONResponseSerializer alloc]init] autorelease];
    responseSerializer.readingOptions = NSJSONReadingAllowFragments;
    responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
    responseSerializer.acceptableStatusCodes = [NSIndexSet indexSetWithIndexesInRange:NSMakeRange(200, 2)];
    requestManager.responseSerializer = responseSerializer;

到这一个：

    requestManager.responseSerializer = [AFHTTPResponseSerializer serializer];

因为您正在使用@＆＃34; text / html＆＃34;的acceptableContentType，我假设您在响应调用时不需要JSON序列化程序。所以这应该适合你的情况。
