如何在nsurlsession中传递必应搜索Ocp-Apim-Subscription-Key？

Question

到目前为止，我使用Azure Data Market“Bing Search”API在我的Objective C项目中执行图像搜索。

下面是执行搜索的部分代码：

{
        NSData *authData;
        NSString *authKey = @"<enter Subscription key here!>";
        authData = [[[NSString alloc] initWithFormat:@"%@:%@", authKey, authKey] dataUsingEncoding:NSUTF8StringEncoding];
        NSString *authValue = [[NSString alloc] initWithFormat:@"Basic %@", [self stringByEncodingInBase64:authData]];
        NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
        [config setHTTPAdditionalHeaders:@{@"Authorization": authValue}];

        // Timeout settings...
        config.timeoutIntervalForRequest = 6.0;
        config.timeoutIntervalForResource = 8.0;

        NSMutableCharacterSet * URLQueryPartAllowedCharacterSet;
        URLQueryPartAllowedCharacterSet = [[NSCharacterSet URLQueryAllowedCharacterSet] mutableCopy];
        [URLQueryPartAllowedCharacterSet removeCharactersInString:@"&+=?"];
        NSString * escapedValue = [searchKeys stringByAddingPercentEncodingWithAllowedCharacters:URLQueryPartAllowedCharacterSet];
        NSString * urlString = [[NSString alloc] initWithFormat:
            @"https://api.datamarket.azure.com/Data.ashx/Bing/Search/v1/Image?Query='%@'&$top=20&$format=json", escapedValue];
        NSURL *JSONURL = [NSURL URLWithString:urlString];
        NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:JSONURL];
        NSURLSessionDataTask * dataTask =
        [[NSURLSession sessionWithConfiguration:config] dataTaskWithRequest:request completionHandler:^
        (NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {                                                                
         < PROCESS YOUR DATA HERE >    
         }];
        [dataTask resume];
     }

假设新密钥是qwerty12345，如果您要发布解决方案。

Ocp-Apim-Subscription-Key应该在报头中传递。因此，将使用NSURLSessionConfiguration及其方法setHTTPAdditionalHeaders：

NSString *authKey = @"<enter NEW key>";
NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
[config setHTTPAdditionalHeaders:@{@"Ocp-Apim-Subscription-Key": authKey}];
