Question

我正在尝试使用AFNetworking在CouchDB服务器中创建HTTP PUT请求。服务器需要HTTP主体中的base64编码字符串。如何在不使用AFNetworking将HTTP正文作为键/值对发送的情况下发出此请求？

我开始看这个方法：

- (void)putPath:(NSString *)path
 parameters:(NSDictionary *)parameters
    success:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success
    failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error))failure;

但这里的参数类型为：NSDictionary。我只想在HTTP正文中发送base64编码的字符串，但不与密钥相关联。有人能指出我使用的适当方法吗？谢谢！

Answer 1

Hejazi的答案很简单，应该很有效。

如果出于某种原因，您需要非常具体地针对一个请求 - 例如，如果您需要覆盖标题等 - 您还可以考虑构建自己的NSURLRequest。

这是一些（未经测试的）示例代码：

// Make a request...
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:myURL];

// Generate an NSData from your NSString (see below for link to more info)
NSData *postBody = [NSData base64DataFromString:yourBase64EncodedString];

// Add Content-Length header if your server needs it
unsigned long long postLength = postBody.length;
NSString *contentLength = [NSString stringWithFormat:@"%llu", postLength];
[request addValue:contentLength forHTTPHeaderField:@"Content-Length"];

// This should all look familiar...
[request setHTTPMethod:@"POST"];
[request setHTTPBody:postBody];

AFHTTPRequestOperation *operation = [client HTTPRequestOperationWithRequest:request success:success failure:failure];
[client enqueueHTTPRequestOperation:operation];

NSData类别方法base64DataFromString为available here。

您可以使用multipartFormRequestWithMethod方法，如下所示：

NSURLRequest *request = [self multipartFormRequestWithMethod:@"PUT" path:path parameters:parameters constructingBodyWithBlock:^(id <AFMultipartFormData> formData) {
    [formData appendString:<yourBase64EncodedString>]
}];
AFHTTPRequestOperation *operation = [client HTTPRequestOperationWithRequest:request success:success failure:failure];
[client enqueueHTTPRequestOperation:operation];

这里有一个发送原始json 的示例：

NSDictionary *dict = ...
NSError *error;
NSData *dataFromDict = [NSJSONSerialization dataWithJSONObject:dict
                                                           options:NSJSONWritingPrettyPrinted
                                                             error:&error];

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

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

req.timeoutInterval = 30;
[req setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[req setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[req setValue:IF_NEEDED forHTTPHeaderField:@"Authorization"];

[req setHTTPBody:dataFromDict];

[[manager dataTaskWithRequest:req completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
    if (!error) {
        NSLog(@"%@", responseObject);
    } else {
        NSLog(@"Error: %@, %@, %@", error, response, responseObject);
    }
}] resume];

Answer 4

 NSData *data = someData;
 NSMutableURLRequest *requeust = [NSMutableURLRequest requestWithURL:          
 [NSURL URLWithString:[self getURLWith:urlService]]];

[reqeust setHTTPMethod:@"PUT"];
[reqeust setHTTPBody:data];
[reqeust setValue:@"application/raw" forHTTPHeaderField:@"Content-Type"];

NSURLSessionDataTask *task = [manager uploadTaskWithRequest:requeust fromData:nil progress:^(NSProgress * _Nonnull uploadProgress) {

} completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {

}];
[task resume];

我正在使用AFNetworking 2.5.3并为AFHTTPRequestOperationManager创建新的POST方法。

extension AFHTTPRequestOperationManager {

    func POST(URLString: String!, rawBody: NSData!, success: ((AFHTTPRequestOperation!, AnyObject!) -> Void)!, failure: ((AFHTTPRequestOperation!, NSError!) -> Void)!) {

        let request = NSMutableURLRequest(URL: NSURL(string: URLString, relativeToURL: baseURL)!)
        request.HTTPMethod = "POST"
        request.HTTPBody = rawBody

        let operation = HTTPRequestOperationWithRequest(request, success: success, failure: failure)

        operationQueue.addOperation(operation)
    }

}

请使用以下方法。

# registrations_controller.rb

def new
  build_resource({})
  yield resource if block_given?
  respond_with resource
end

protected

def build_resource(hash = nil)
  self.resource = resource_class.new_with_session(hash || {}, session).decorate
end
