AFNetworking 2.0 域=AFNetworkingErrorDomain 代码=-1011 “请求失败：内部服务器错误 (500)

Question

我正在尝试使用子类 AFHTTPRequestOperationManager 将我的代码转换为 AFNetworking 2.0。这是我的代码

+ (NSAFNetwokingRequestManager *)sharedClient {
    static NSAFNetwokingRequestManager *_sharedClient = nil;

    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        _sharedClient = [[self alloc] initWithBaseURL:[NSURL URLWithString:GET_CAR_BRAND]];
    });
    return _sharedClient;
}
- (instancetype)initWithBaseURL:(NSURL *)url
{
    self = [super initWithBaseURL:url];
     if (self) {
    self.responseSerializer = [AFXMLParserResponseSerializer serializer];
    self.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"application/soap+xml"];
    self.requestSerializer = [AFHTTPRequestSerializer serializer];
    [self.requestSerializer setValue:@"application/soap+xml" forHTTPHeaderField:@"Content-type"];
}

    return self;
}
- (void)requestBrandcompletion:(NSAFNetwokingRequestManagerCompletionBlock)completion {
    NSString *soapRequest=@"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
    "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
    "<soap:Body>\n"
    " <CarBrandExt xmlns=\"http://www.nohausystems.nl/\" />\n"
    "</soap:Body>\n"
    "</soap:Envelope>\n";
    NSString *msgLength = [NSString stringWithFormat:@"%i",[soapRequest length]];
    [self POST:GET_CAR_BRAND parameters:Nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
          [formData appendPartWithHeaders:[NSDictionary dictionaryWithObjectsAndKeys:@"text/xml; charset=utf-8", @"Content-Type", msgLength, @"Content-Length", nil] body:[soapRequest dataUsingEncoding:NSUTF8StringEncoding]];
    } success:^(AFHTTPRequestOperation *operation, id responseObject) {
        if (completion) {
            completion(YES, responseObject);
        }
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        if (completion) {
            completion(NO, nil);
            NSLog(@"Unable to fetch record error %@ with user info %@.", error, error.userInfo);
        }
    }];
}

我收到此错误 Domain=AFNetworkingErrorDomain Code=-1011 "请求失败：内部服务器错误 (500)。谁能告诉我我在这里做错了什么？ 收到此回复：

{ status code: 500, headers {
    "Cache-Control" = private;
    "Content-Length" = 509;
    "Content-Type" = "application/soap+xml; charset=utf-8";
    Date = "Thu, 13 Mar 2014 12:59:45 GMT";
    Server = "Microsoft-IIS/7.5";
    "X-AspNet-Version" = "2.0.50727";
    "X-Powered-By" = "ASP.NET";
} }

Answer 1

在您的代码中：

[self POST:GET_CAR_BRAND parameters:Nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
          [formData appendPartWithHeaders:[NSDictionary dictionaryWithObjectsAndKeys:@"text/xml; charset=utf-8", @"Content-Type", msgLength, @"Content-Length", nil] body:[soapRequest dataUsingEncoding:NSUTF8StringEncoding]];

将内容类型定义为“text/xml”，而服务器显然期待“application/soap+xml”。您应该尝试将那部分代码更改为：

[self POST:GET_CAR_BRAND parameters:Nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
          [formData appendPartWithHeaders:[NSDictionary dictionaryWithObjectsAndKeys:@"application/sopa+xml; charset=utf-8", @"Content-Type", msgLength, @"Content-Length", nil] body:[soapRequest dataUsingEncoding:NSUTF8StringEncoding]];

更新建议：

尝试添加：

[self.requestSerializer setValue:@"application/soap+xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];

在您的 - (instancetype)initWithBaseURL:(NSURL *)url 方法的末尾。

如果这没有帮助，我建议做一些更详细的网络请求调试。你可以例如设置AFNetworkActivityLogger 将请求/响应信息记录到控制台。

Answer 2

只是一个想法，在使用 BASEURL 和 AFNetworking 时要小心。如果您向 AFNetworking 提供确切的端点 url，它可能会失败。

例如：

你有一个端点URL = http://myweb.com/api.php

在上述情况下，如果您使用 AFNetworking，则 BASEURL != URL 而它应该类似于 BASEURL=http://myweb.com/ 并且在调用任何请求时提供 URL = api.php强>。 AFNetworking 附加 BASEURL + URL 并创建一个完整的端点 url。

虽然上述答案可能不适合您的情况。但万一它有助于驯服其他问题，或者也可能是你的情况。

谢谢。

Answer 3

“请求失败：不可接受的内容类型：应用程序/soap+xml”错误是由

生成的

- (BOOL)validateResponse:(NSHTTPURLResponse *)response
                    data:(NSData *)data
                   error:(NSError * __autoreleasing *)error

AFHTTPResponseSerializer 在出现意外 MIME 类型的响应时的方法。

您可以使用以下代码修复它

self.responseSerializer = [AFXMLParserResponseSerializer serializer];
NSSet *set = self.responseSerializer.acceptableContentTypes;
self.responseSerializer.acceptableContentTypes = [set setByAddingObject:@"application/soap+xml"];

或修改 AFXMLDocumentResponseSerializer - 将“application/soap+xml”添加到可接受的内容类型：

- (instancetype)init {
    self = [super init];
    if (!self) {
        return nil;
    }

    self.acceptableContentTypes = [[NSSet alloc] initWithObjects:@"application/xml", @"text/xml", @"application/soap+xml", nil];

    return self;
}

我猜以下不会解决这个问题

[self.requestSerializer setValue:@"application/soap+xml" forHTTPHeaderField:@"Content-type"];

试试这个代码：

[self.requestSerializer setValue:@"application/soap+xml" forHTTPHeaderField:@"Accept"];
