xCode - Mashape Unirest

Question

我需要你的帮助。我在MaShape上为Metascore找到了一个API，但是我无法让它工作。我使用Cocoapod下载Unirest框架并复制粘贴了Mashape的代码片段

NSDictionary* headers = @{@"X-Mashape-Authorization": @"wZrjWIiAsqdSLGIh3DQzrKoZ5Y3wlo6E"};
NSDictionary* parameters = @{@"title": @"The Elder Scrolls V: Skyrim", @"platform": 1, };

UNIHttpJsonResponse* response = [[UNIRest post:^(UNIBodyRequest* request) {
  [request setUrl:@"https://byroredux-metacritic.p.mashape.com/find/game"];

  [request setHeaders:headers];
  [request setParameters:parameters];
}] asJson];

它给了我一堆错误，我把它修正成这样：

NSDictionary* headers = @{@"X-Mashape-Authorization": @"wZrjWIiAsqdSLGIh3DQzrKoZ5Y3wlo6E"};
    NSDictionary* parameters = @{@"title": @"The Elder Scrolls V: Skyrim", @"platform": @"1", };

    UNIHTTPJsonResponse* response = [[UNIRest post:^(UNISimpleRequest* request) {
        [request setUrl:@"https://byroredux-metacritic.p.mashape.com/find/game"];

        [request setHeaders:headers];
        [request setParameters:parameters];
    }] asJson];

但是，每当我去调试代码并查看响应内部时，它都是空的，就好像api没有工作一样。你们能告诉我我做错了什么吗？

谢谢

您的(固定的)代码片段看起来很好(第一个代码片段确实是错误的)，您应该能够像这样打印结果：

UNIHTTPJsonResponse *response = [[UNIRest post:^(UNISimpleRequest *request) {
    [request setUrl:@"https://byroredux-metacritic.p.mashape.com/find/game"];

    [request setHeaders:headers];
    [request setParameters:parameters];
}] asJson];

NSDictionary *json = [NSJSONSerialization JSONObjectWithData:response.rawBody
                                                         options:kNilOptions
                                                           error:nil];
NSLog(@"Response status: %ld\n%@", (long) response.code, json);

但是，与其执行同步调用，我还建议您切换到异步方式，并检查进程和JSON解析过程中的任何错误：

[[UNIRest post:^(UNISimpleRequest *request) {
    [request setUrl:@"https://byroredux-metacritic.p.mashape.com/find/game"];
    [request setHeaders:headers];
    [request setParameters:parameters];
}] asJsonAsync:^(UNIHTTPJsonResponse* response, NSError *error) {
    if (error) {
        // Do something with the error
    }

    NSError *jsonError;
    NSDictionary *json = [NSJSONSerialization JSONObjectWithData:response.rawBody
                                                         options:kNilOptions
                                                           error:&jsonError];
    if (jsonError) {
        // Do something with the error
    }

    NSLog(@"Async response status: %ld\n%@", (long) response.code, json);

    // Unirest also provides you this which prevents you from doing the parsing
    NSLog(@"%@", response.body.JSONObject);
}];
