调用 AFNetworking 响应失败块而不是成功块

Question

当我收到状态代码 200 时，正在调用 AFNetworking 响应 failure 块。如何让 success 被调用？

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:@"http://128.199.94.58/test/bt/client_token.php" parameters:nil
     success:^(AFHTTPRequestOperation *operation, id responseObject) {
         self.clientToken = responseObject[@"customerID"];
         NSLog(@"Client Token received.");
     }
     failure:^(AFHTTPRequestOperation *operation, NSError *error) {
         // Handle failure communicating with your server
         NSLog(@"Client Token request failed.%@",operation.responseString);
         NSLog(@"error code %ld",(long)[operation.response statusCode]);
     }];

Answer 1

查看error的值。它会告诉您连接失败的原因。 "Failure" 在此上下文中与状态代码无关。返回“404”仍然是 "success." 失败意味着您无法完成操作。

Answer 2

我运行这段代码，它可以找到。

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
[manager GET:@"http://128.199.94.58/test/bt/client_token.php" parameters:nil
     success:^(AFHTTPRequestOperation *operation, id responseObject) {
         NSDictionary* json = [NSJSONSerialization JSONObjectWithData:responseObject
                                                              options:kNilOptions
                                                                error:nil];
         self.clientToken = json[@"customerID"];
         NSLog(@"Client Token received.");
     }
     failure:^(AFHTTPRequestOperation *operation, NSError *error) {
         // Handle failure communicating with your server
         NSLog(@"Client Token request failed.%@",operation.responseString);
         NSLog(@"error code %ld",(long)[operation.response statusCode]);
     }];

回复是：

json:
{
    customerID = "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";

它可能适合你。

Answer 3

使用acceptableStatusCodes如下：

 AFHTTPRequestOperationManager *manager =  [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.requestSerializer = [TimeoutAFJSONRequestSerializer serializer];
NSMutableIndexSet* codes = [[NSMutableIndexSet alloc] init];
[codes addIndex: 200];
manager.responseSerializer.acceptableStatusCodes = codes;

[manager GET:urlString parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject)
 {


 } failure:^(AFHTTPRequestOperation *operation, NSError *error)
 {
 }];

Answer 4

如果您在失败块中检查错误，它会清楚地表明 invalid content type。您需要设置管理器的内容类型如下

manager.requestSerializer = [AFJSONRequestSerializer serializer];

Answer 5

试试这个

manager.responseSerializer = [AFHTTPResponseSerializer serializer];

并成功阻止

 success:^(AFHTTPRequestOperation *operation, id responseObject) {
     NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:manager.responseData options:kNilOptions error:nil];
     self.clientToken = dic[@"customerID"];
     NSLog(@"Client Token received.");
 }

调用 AFNetworking 响应失败块而不是成功块
