【问题描述】：

我正在尝试正确实现OHHTTPStubs，但遇到了一些麻烦。

我想做这个库所做的事情。向 URL 发出请求并返回模拟的 JSON 响应。

这就是我设置它的方式，但没有任何东西被正确调用，甚至没有运行存根。

- (void)testWithOHHTTP 
    [OHHTTPStubs initialize];

        [OHHTTPStubs stubRequestsPassingTest:^BOOL(NSURLRequest *request) 
            return [request.URL.host isEqualToString:@"http://www.myweb.com"];
         withStubResponse:^OHHTTPStubsResponse*(NSURLRequest *request) 
            NSDictionary* obj = @ @"key1": @"value1", @"key2": @[@"value2A", @"value2B"] ;
            return [OHHTTPStubsResponse responseWithJSONObject:obj statusCode:200 headers:nil];
        ];

        NSURL *URL = [NSURL URLWithString:@"http://www.myweb.com"];
        NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:URL];

        NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];

        [OHHTTPStubs setEnabled:YES forSessionConfiguration:config];

        NSURLSession *session = [NSURLSession sessionWithConfiguration:config];


        [request setHTTPMethod:@"GET"];

        NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) 

            NSLog(@"#### Data: %@, Response: %@, Error: %@", data, response, error);
            NSDictionary *dataJSON = [NSJSONSerialization JSONObjectWithData:data options:0 error:&error];
            NSLog(@"#### %@", dataJSON);


        ];
        [dataTask resume];

        NSLog(@"All stubs: %@", [OHHTTPStubs allStubs]);

kevinosaurio 提供的答案是更改此行：

[request.URL.host isEqualToString:@"http://www.myweb.com"];

到

[request.URL.host isEqualToString:@"www.myweb.com"];

【参考方案1】：

你的问题是你的主机是 www.myweb.com 没有http://www.myweb.com。

...

[OHHTTPStubs stubRequestsPassingTest:^BOOL(NSURLRequest *request) 
    return [request.URL.host isEqualToString:@"www.myweb.com"];
 withStubResponse:^OHHTTPStubsResponse*(NSURLRequest *request) 
    NSDictionary* obj = @ @"key1": @"value1", @"key2": @[@"value2A", @"value2B"] ;
    return [OHHTTPStubsResponse responseWithJSONObject:obj statusCode:200 headers:nil];
];
...

【讨论】：

我试过了，但每次都会出现这个错误。 Error Domain=NSURLErrorDomain Code=-1002 "unsupported URL" UserInfo=NSUnderlyingError=0x1c024f0c0 Error Domain=kCFErrorDomainCFNetwork Code=-1002 "(null)", NSErrorFailingURLStringKey=www.myweb.com, NSErrorFailingURLKey=www.myweb.com, NSLocalizedDescription=unsupported URL

您只需要在这一行中更改它：[request.URL.host isEqualToString:@"www.myweb.com"]。在其他人使用："http://www.myweb.com"
