ios - 如何使用数组作为标题和 AFNetworking 进行 POST

Question

这是标题:

                "url": "{{host}}/images/bla",
            "method": "POST",
            "header": [
                {
                    "key": "Content-Type",
                    "value": "application/json",
                    "description": ""
                },
                {
                    "key": "Authorization",
                    "value": "Bearer token",
                    "description": ""
                }
            ],
            "body": { ... }

我尝试分两种情况解决:

案例 1(崩溃):

NSDictionary *headerDict = @{@"key": @"Content-Type",
                                 @"value": @"application/json",
                                 @"description": @""};

NSDictionary *headerDict1 = @{@"key": @"Authorization",
                                 @"value": kBearerKey,
                                 @"description": @""};
NSArray *headerArray = @[headerDict, headerDict1];

[weakSelf.requestOperationManager.requestSerializer setValue:headerArray forHTTPHeaderField:@"header"];

案例 2(不崩溃但也不起作用):

weakSelf.requestOperationManager.requestSerializer = [AFHTTPRequestSerializer serializer];
[weakSelf.requestOperationManager.requestSerializer setValue:@"Content-Type" forHTTPHeaderField:@"key"];
[weakSelf.requestOperationManager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"value"];
[weakSelf.requestOperationManager.requestSerializer setValue:@"Authorization" forHTTPHeaderField:@"key"];
[weakSelf.requestOperationManager.requestSerializer setValue:kBearerKey forHTTPHeaderField:@"value"];

无论如何，在情况 1 中会生成一个警告(并且也会发生崩溃)，因为 setValue 应该是 NSString 而不是 NSArray.

Answer 1

例如，您可以将 NSMutableDictionary 中的所有 header 值保留为键/值对

NSDictionary *headersDict = @{@"Content-Type": @"application/json",
                                  @"Authorization": kBearerKey };

然后你可以迭代键值并设置http header

[headersDict enumerateKeysAndObjectsUsingBlock:^(NSString *key, NSString *obj, BOOL *stop) {
        [requestManager.requestSerializer setValue:obj forHTTPHeaderField:key];
    }];

在您的情况下，您使用的是数组。您可以迭代数组并设置 header 值，希望这会有所帮助。

for (NSDictionary *dict in headerArray) {

        NSString *key = [dict objectForKey:@"key"];
        NSString *value = [dict objectForKey:@"value"];

        [requestManager.requestSerializer setValue:value forHTTPHeaderField:key];
}
