Ios 如何使用数组作为标题和AFN创建POST

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": { ... }

我试图在两种情况下解决这个问题：

案例1（崩溃）：

案例2（不会崩溃但也不起作用）：

无论如何，在案例1中，会生成一个警告（也会发生崩溃），因为

setValue

预期为

NSString

而不是

NSArray

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

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

然后可以迭代键值并设置http头

[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头值，希望这对您有所帮助

for (NSDictionary *dict in headerArray) {

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

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

试试这个

NSError *error;

NSData *jsonData = [NSJSONSerialization:headerArray options:NSJSONWritingPrettyPrinted error:&error];                                                                                 

NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

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

试试这个：

AF3网络

NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject: headerArray options:NSJSONWritingPrettyPrinted error:&error];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

NSMutableURLRequest *req = [[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:url parameters:nil error:nil];

req.timeoutInterval= [[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue];
[req setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[req setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[req setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];


NSURLSessionUploadTask *uploadTask;
uploadTask = [manager
              uploadTaskWithStreamedRequest:req
              progress:^(NSProgress * _Nonnull uploadProgress) {
                  dispatch_async(dispatch_get_main_queue(), ^{
                  });
              }
              completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
                  if (error) {
                      NSLog(@"Error: %@", [[NSString alloc]initWithData:[[error valueForKey:@"userInfo"] valueForKey:@"com.alamofire.serialization.response.error.data"] encoding:NSUTF8StringEncoding]);

                  } else {
                  }
              }];

[uploadTask resume];

您需要将数组转换为json字符串：NSData*jsonData2=[NSJSONSerialization dataWithJSONObject:headerArray选项：NSJSONWriting预打印错误：&error]；NSString*jsonString=[[NSString alloc]initWithData:jsonData2编码：NSUTF8StringEncoding]；这是可行的，但问题是数据解释器在@“application/json”中添加了一个“\”，它看起来像@“application\/json”：（lldb）po headerString[{“key”：“Content Type”，“value”：“application\/json”，“description”：“}，{“key”：“Authorization”，“value”：“Bearer xpkavsckjsfcwcxfcxfodtibu38b6momzpw…”，“description”：“}]请尝试此

weakSelf.requestOperationManager.responseSerializer.acceptableContentTypes=[NSSet setWithObject:@“text/plain”]；

NSError *error;

NSData *jsonData = [NSJSONSerialization:headerArray options:NSJSONWritingPrettyPrinted error:&error];                                                                                 

NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

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

NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject: headerArray options:NSJSONWritingPrettyPrinted error:&error];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

NSMutableURLRequest *req = [[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:url parameters:nil error:nil];

req.timeoutInterval= [[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue];
[req setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[req setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[req setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];


NSURLSessionUploadTask *uploadTask;
uploadTask = [manager
              uploadTaskWithStreamedRequest:req
              progress:^(NSProgress * _Nonnull uploadProgress) {
                  dispatch_async(dispatch_get_main_queue(), ^{
                  });
              }
              completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
                  if (error) {
                      NSLog(@"Error: %@", [[NSString alloc]initWithData:[[error valueForKey:@"userInfo"] valueForKey:@"com.alamofire.serialization.response.error.data"] encoding:NSUTF8StringEncoding]);

                  } else {
                  }
              }];

[uploadTask resume];

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

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