我在从 AFNetworking 发出 POST 请求时在 error.userInfo 中收到此响应。
谁能告诉我是我遗漏了什么明显的东西还是我的服务器端需要修复什么？
Request Failed with Error: Error Domain=AFNetworkingErrorDomain Code=-1016 "Expected content type {( "text/json", "application/json", "text/javascript" )}, got text/html" UserInfo=0x6d7a730 {NSLocalizedRecoverySuggestion=index test, AFNetworkingOperationFailingURLResponseErrorKey=, NSErrorFailingURLKey=http://54.245.14.201/, NSLocalizedDescription=Expected content type {( "text/json", "application/json", "text/javascript" )}, got text/html, AFNetworkingOperationFailingURLRequestErrorKey=http://54.245.14.201/>}, { AFNetworkingOperationFailingURLRequestErrorKey = "http://54.245.14.201/>"; AFNetworkingOperationFailingURLResponseErrorKey = ""; NSErrorFailingURLKey = "http://54.245.14.201/"; NSLocalizedDescription = "Expected content type {(\n \"text/json\",\n \"application/json\",\n
\"text/javascript\"\n)}, got text/html"; NSLocalizedRecoverySuggestion = "index test"; }
我正在使用这段代码；
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
[httpClient registerHTTPOperationClass:[AFJSONRequestOperation class]];
[httpClient setDefaultHeader:@"Accept" value:@"application/json"];
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
@"Ans", @"name",
@"29", @"age",
nil];
NSMutableURLRequest *request = [httpClient requestWithMethod:@"POST" path:@"/" parameters:params];
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request
success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
NSLog(@"Success");
NSLog(@"%@",JSON);
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
NSLog(@"Request Failed with Error: %@, %@", error, error.userInfo);
NSLog(@"Failure");
}];
[operation start];
[operation waitUntilFinished];
最佳答案
默认情况下，AFJSONRequestOperation 仅接受来自服务器的“text/json”、“application/json”或“text/javascript”内容类型，但您得到的是“text/html”。
在服务器上修复会更好，但您也可以在您的应用中添加可接受的“text/html”内容类型:
[AFJSONRequestOperation addAcceptableContentTypes:[NSSet setWithObject:@"text/html"]];
它对我有用，希望对您有所帮助!
