如何正确设置AFNetworking获取请求？ [英] How I properly setup an AFNetworking Get Request?

问题描述

我正在尝试从服务器中检索一行代码，并在我的 NSUserDefaults 中实现它。

I'm trying to retrieve a line of code from my server and implement it in my NSUserDefaults.

现在，这就是我的 appdelegate.m 的样子：

Right now, this is what my appdelegate.m looks like:

NSDictionary* defaults = @{@"server_addr": @"http://156.92.15.802"};
    [[NSUserDefaults standardUserDefaults] registerDefaults:defaults];

http://156.92.15.802 url是我需要从服务器中获取的部分。

The http://156.92.15.802 url is the part that I need to GET from my server.

如果我的服务器上有一个名为Example.txt的文件，并且该文件中有一行，例如 http://156.92.15.802 ，如何使用AFNetworking检查服务器上的文件，然后将其添加到 NSUserDefaults ？

If my server has a file named Example.txt on it and within that file is a single line that like http://156.92.15.802, how can I use AFNetworking to check the file on my server and then add it to the NSUserDefaults?

推荐答案

步骤如下：

1. 下载 Example.txt 文件


2. 读取下载的 txt 文件放入 NSString *


3. 将此 NSString * 保存到您的 NSUserDefaults

1. Download the Example.txt file
2. Read the downloaded txt file into a NSString*
3. Save this NSString* into your NSUserDefaults

- (void)requestTextFile {
  NSString *urlString = @"http://156.92.15.802/Example.txt";

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

  NSURL *URL = [NSURL URLWithString:urlString];
  NSURLRequest *request = [NSURLRequest requestWithURL:URL];

  NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) {
    NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil];
    return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]];
  } completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {
    NSString* content = [NSString stringWithContentsOfFile:filePath.relativePath encoding:NSUTF8StringEncoding error:NULL];
    NSLog(@"content = %@", content);
    //save this content to your NSUserDefaults
    //...
  }];
  [downloadTask resume];
}
