本文介绍了iOS判断网络请求超时的方法，代码具体如下：
+ (AFHTTPRequestOperation *)requestOperationWithUrl:(NSString *)url
requetMethod:(NSString *)method
parAMData:(NSDictionary *)aParamData
constructingBodyWithBlock:(void (^)(id formData))block
success:(successBlock)success
fAIlure:(failureBlock)failure {
AFHTTPRequestSerializer *requestSerializer = [AFJSONRequestSerializer serializer];
NSMutableURLRequest *request;
if (block) {
method = @"POST";
request = [requestSerializer multipartFormRequestWithMethod:method URLString:url parameters:aParamData constructingBodyWithBlock:block error:nil];
}else{
request = [requestSerializer requestWithMethod:method URLString:url parameters:aParamData error:nil];
}
AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
AFJSONResponseSerializer *responseSerializer = [AFJSONResponseSerializer serializer];
responseSerializer.removesKeysWithNullValues = YES;
responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
op.responseSerializer = responseSerializer;
__weak AFHTTPRequestOperation *weakOp = op;
[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
if ([responseObject[@"code"] integerValue] == 0) {
if (success) {
// success(weakOp, aParamData, responseObject[@"list"]);
success(weakOp, aParamData, responseObject);
}
}else{
NSLog(@"operation error msg = [%@]", responseObject[@"description"]);
if (failure) {
failure(weakOp, aParamData, [self errorWithRet:responseObject]);
}
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"operation failed = [%@] error = [%@]", operation, error);
if (failure) {
failure(weakOp, aParamData, error);
}
}];
return op;
}
打印 error
Error Domain=NSURLErrorDomain Code=-1001 "请求超时。"
UserInfo={
NSErrorFailingURLStringKey=http://123.56.109.92/refitcar/service.s?sn=, _kCFStreamErrorCodeKey=-2102, NSErrorFailingURLKey=http://123.56.109.92/refitcar/service.s?sn=, NSLocalizedDescription=请求超时。, _kCFStreamErrorDomainKey=4,
NSUnderlyingError=0x167da8e0 {
Error Domain=kCFErrorDomainCFNetwork Code=-1001 "请求超时。"
UserInfo={
_kCFStreamErrorCodeKey=-2102,
NSErrorFailingURLStringKey=http://123.56.109.92/refitcar/service.s?sn=,

NSLocalizedDescription=请求超时。,
_kCFStreamErrorDomainKey=4
}
}
}
可见：
po error.localizedDescription 请求超时。
po error.code -1001
po error.userInfo
{
NSErrorFailingURLKey = "http://123.56.109.92/refitcar/service.s?sn=";
NSErrorFailingURLStringKey = "http://123.56.109.92/refitcar/service.s?sn=";
NSLocalizedDescription = "\U8bf7\U6c42\U8d85\U65f6\U3002";
NSUnderlyingError = "Error Domain=kCFErrorDomainCFNetwork Code=-1001 \"\U8bf7\U6c42\U8d85\U65f6\U3002\" UserInfo={_kCFStreamErrorCodeKey=-2102, NSErrorFailingURLStringKey=http://123.56.109.92/refitcar/service.s?sn=, NSErrorFailingURLKey=http://123.56.109.92/refitcar/service.s?sn=, NSLocalizedDescription=\U8bf7\U6c42\U8d85\U65f6\U3002, _kCFStreamErrorDomainKey=4}";
"_kCFStreamErrorCodeKey" = "-2102";
"_kCFStreamErrorDomainKey" = 4;
}
所以使用 error.code是否等于 -1001 判断请求超时
