将 HTTP 正文设置为 AFNetworking 而不是使用本机请求

Question

我最近一直在尝试让 AFNetworking 像处理本机请求一样工作，我一直使用 AFNetworking 上传 POST 或 GET。但它从未正确上传我的图像。它总是上传到损坏的服务器，我已经在这个参考中解释了这个问题：Uploading image to server reached damaged using AFNetworking

我已尝试将本机 NSURLConnection.sendSynchronousRequest 与 HTTP 正文一起使用，它已上传且未损坏。并且这段代码完全可以工作，但我在 AFNetworking 中需要它，因为它只支持 IOS 8 + 以及更多原因。

        let baseURL = ""
        let selectedImage = self.userImage.image
        let imageData = NSData(data: UIImageJPEGRepresentation(selectedImage!, 0.5)!)

        let request = NSMutableURLRequest()
        request.URL = NSURL(string: baseURL)
        request.HTTPMethod = "POST"
        request.addValue("image/jpeg", forHTTPHeaderField: "Content-Type")
        let body = NSMutableData(data: imageData)
        request.HTTPBody = body

 do {
            let responseData = try NSURLConnection.sendSynchronousRequest(request, returningResponse:nil)
            let responseString = String(data: responseData, encoding: NSUTF8StringEncoding)

            print("User image successfully uploaded navigating to home services")


        } catch (let error as NSError) {
}

     NSMutableDictionary *contentDictionary = [[NSMutableDictionary alloc]init];
    [contentDictionary setValue:@"name" forKey:@"email"];
    [contentDictionary setValue:@"name" forKey:@"username"];
    [contentDictionary setValue:@"name" forKey:@"password"];
   [contentDictionary setValue:@"name" forKey:@"firstName"];
    [contentDictionary setValue:@"name" forKey:@"lastName"];

    NSData *data = [NSJSONSerialization dataWithJSONObject:contentDictionary options:NSJSONWritingPrettyPrinted error:nil];
    NSString *jsonStr = [[NSString alloc] initWithData:data
                                          encoding:NSUTF8StringEncoding];
NSLog(@"%@",jsonStr);

NSString *urlString = [NSString stringWithFormat:@"http://testgcride.com:8081/v1/users"];
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];
   [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

[request setHTTPBody:[jsonStr dataUsingEncoding:NSUTF8StringEncoding]];

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager.requestSerializer setAuthorizationHeaderFieldWithUsername:@"moinsam" password:@"cheese"];
manager.requestSerializer = [AFJSONRequestSerializer serializer];

AFHTTPRequestOperation *operation = [manager    HTTPRequestOperationWithRequest:request success:<block> failure:<block>];

试试这个

以下是 Objective-c 中的一个解决方案，也可以为 swift 复制相同的过程。 为AFHTTPRequestOperationManager 创建一个对象，如下所示。

 [[AFHTTPRequestOperationManager alloc] initWithBaseURL:@"www.google.com"];

现在用键值对定义NSDictionary，这将是您的请求正文的参数。

NSDictionary *parameters = @{
                             @"paramaname": value,
                             @"paramaname":value
                        };

现在，当调用POST请求时

 [self.manager POST:@"someMethodName" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSDictionary * responseDict = (NSDictionary *)responseObject;
    NSLog(@"responseDict : %@",responseDict);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"error  : %@ code %d",error.localizedDescription,error.code);
    }
}];

这是您可以使用 AFNetworking 发送带有参数的 POST 请求的方法。
