本文介绍了ios判断网络请求超时的方法，代码具体如下：
我要评论
+ (afhttprequestoperation *)requestoperationwithurl:(nsstring *)url
requetmethod:(nsstring *)method
paramdata:(nsdictionary *)aparamdata
constructingbodywithblock:(void (^)(id <afmultipartformdata> 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=,
nserrorfailingurlkey=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
