由于公司用的是MKNetworkKit第三方的網(wǎng)絡(luò)請求框架，最近在做一個新項目的時候有一個接口是POST一個mobile字段來獲取驗證碼，但是卻發(fā)現(xiàn)，不論是系統(tǒng)的請求還是AFNETWork都可以正常調(diào)用。
系統(tǒng)請求1
//第一步，創(chuàng)建URLNSURL*url = [NSURLURLWithString:@"https://tms.beta.ule.com/deliveryApp/router/rest?method=delivery.deliverystaff.sendsmscode"];
//第二步，創(chuàng)建請求
NSMutableURLRequest*request = [[NSMutableURLRequestalloc]initWithURL:urlcachePolicy:NSURLRequestUseProtocolCachePolicytimeoutInterval:10];
[request setHTTPMethod:@"POST"];
NSString*str =@"mobile=***********";//設(shè)置參數(shù)
NSData*data = [strdataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPBody:data];
//第三步，連接服務(wù)器
NSURLConnection*connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];
NSLog(@"%@",request.allHTTPHeaderFields);
[connection start];
系統(tǒng)請求2
//獲得NSURLSession對象NSURLSession*session = [NSURLSessionsharedSession];
//創(chuàng)建請求
NSMutableURLRequest*request = [NSMutableURLRequestrequestWithURL:[NSURLURLWithString:@"https://tms.beta.ule.com/deliveryApp/router/rest"]];
request.HTTPMethod =@"POST";//請求方法
request.HTTPBody = [@"method=delivery.deliverystaff.sendsmscode&mobile=***********"dataUsingEncoding:NSUTF8StringEncoding];//請求體
//創(chuàng)建任務(wù)
NSURLSessionDataTask*task = [sessiondataTaskWithRequest:requestcompletionHandler:^(NSData*data,NSURLResponse*response,NSError*error) {
NSLog(@"%@", [NSJSONSerializationJSONObjectWithData:dataoptions:kNilOptionserror:nil]);
}];
//啟動任務(wù)
[task resume];
MKNetworkKit
UleMK_MKNetworkOperation*op = [[UleMK_MKNetworkOperationalloc]initWithURLString:@"https://tms.beta.ule.com/deliveryApp/router/rest?method=delivery.deliverystaff.sendsmscode"params:nilhttpMethod:@"POST"];[op addParams:@{@"mobile":@"***********"}];
[op addCompletionHandler:^(UleMK_MKNetworkOperation*completedOperation) {
NSLog(@"__%@___",[completedOperationresponseString]);
} errorHandler:^(UleMK_MKNetworkOperation*completedOperation,NSError*error) {
NSLog(@"__%@__",error);
}];
[op start];
UleMK_MKNetworkEngine* engine = [[UleMK_MKNetworkEnginealloc]initWithHostName:@"tms.beta.ule.com"];
UleMK_MKNetworkOperation*op = [engine operationWithPath:@"deliveryApp/router/rest?method=delivery.deliverystaff.sendsmscode"params:@{@"mobile":@"***********"}httpMethod:@"POST"ssl:YES];
[op addCompletionHandler:^(UleMK_MKNetworkOperation*completedOperation) {
NSLog(@"__%@___",[completedOperationresponseString]);
} errorHandler:^(UleMK_MKNetworkOperation*completedOperation,NSError*error) {
NSLog(@"__%@__",error);
}];
[engine enqueueOperation: op];
在緩慢的調(diào)試過程中發(fā)現(xiàn)，拼接一個完整的URL，POST參數(shù)為nil的時候，是可以獲取到驗證碼信息的，那么就把目標放在POST參數(shù)上了。
最后發(fā)現(xiàn)在MKNetworkKit中有一個
//http://stackoverflow.com/questions/1446509/handling-redirects-correctly-with-nsurlconnection
- (NSURLRequest*)connection: (NSURLConnection*)inConnection
willSendRequest: (NSURLRequest*)inRequest
redirectResponse: (NSURLResponse*)inRedirectResponse;
{
// *******start
// yushengyang 20160316 tms.beta.ule.com不支持重定向
if([inRequest.URL.absoluteStringrangeOfString:@"tms.beta.ule.com"].location!=NSNotFound|| [inRequest.URL.absoluteStringrangeOfString:@"tms.ule.com"].location!=NSNotFound) {
returninRequest;
}
// *******end
NSMutableURLRequest*r = [self.requestmutableCopy];
if(inRedirectResponse) {
[rsetURL: [inRequestURL]];
}else{
// Note that we need to configure the Accept-Language header this late in processing
// because NSURLRequest adds a default Accept-Language header late in the day, so we
// have to undo that here.
// For discussion see:
//http://lists.apple.com/archives/macnetworkprog/2009/Sep/msg00022.html
NSString* accept_language =self.shouldSendAcceptLanguageHeader? [selflanguagesFromLocale] :nil;
[rsetValue:accept_languageforHTTPHeaderField:@"Accept-Language"];
}
returnr;
}
在粗體標記中，第一個是我加的代碼，因為這個問題可能做后段接口的同事引起的，所以我只屏蔽該接口。第二個是框架寫的，這里不太明白為何每次都要重新弄一個request，雖然該request就是代理中的，但是不知道為何，只要用的不是inRequest而是self.request通過copy而來的，都會導致收不到驗證碼。
看了看AFNetwork中的處理
- (NSURLRequest*)connection:(NSURLConnection*)connection
willSendRequest:(NSURLRequest*)request
redirectResponse:(NSURLResponse*)redirectResponse
{
if(self.redirectResponse) {
returnself.redirectResponse(connection, request, redirectResponse);
}else{
returnrequest;
}
｝
po self.request.allHTTPHeaderFields
{
}
po inRequest.allHTTPHeaderFields
{
Accept = "*/*";
"Accept-Encoding" = "gzip, deflate";
"Accept-Language" = "en-us";
}
對比了本地self.request和inRequest，雖然有不同的參數(shù)，但是即使本地設(shè)置了也不能生效，此處有疑問，只能單獨處理該域名下的請求。
-(NSURLRequest*)connection:(NSURLConnection*)connection
willSendRequest:(NSURLRequest*)request
redirectResponse:(NSURLResponse*)redirectResponse;
{
if(
redirectResponse){// we don't use the new request built for us, except for the URL
NSURL*newURL=[request URL];
// Previously, store the original request in _originalRequest.
// We rely on that here!
NSMutableURLRequest*newRequest=[_originalRequest mutableCopy];
[newRequest setURL:newURL];
returnnewRequest;
}else{
returnrequest;
}
}
查找到其他博文提到的代碼，我代碼里的redirectResponse是nil，似乎是后臺的接口不支持這種處理。
只用實現(xiàn)了這個block才會有自定義，加上有博文指出這個代理方法的作用是重定向，感覺是MK中有寫雞肋，不過做后臺的同事應(yīng)該在處理上也有問題，特此記錄，與君共勉！
