我尝试使用afnetworking从iPhone模拟器发送帖子数据。我试图检查php页面是否接收到数据。但是很遗憾，它没有收到任何发布数据。我尝试使用var_dump（$ _ POST），但它返回一个空数组。这是我的代码：
用于将数据发送到PHP的iOS代码（ViewController.h）：
- (IBAction)onSend:(id)sender {
NSURL *url = [NSURL URLWithString:@"http://localhost/sample/"];
AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:url];
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:firstnameTextField.text, @"firstname", lastnameTextField.text, @"lastname",nil];
[client postPath:@"sample.php" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
UIAlertView *succesAlert = [[UIAlertView alloc] initWithTitle:@"Success" message:@"Post Success" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
[succesAlert show];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
}];
}
PHP代码（sample.php）：
<?php
if(isset($_POST["firstname"]) && isset($_POST["lastname"]))
{
$fname = $_POST["firstname"];
$lname = $_POST["lastname"];
echo $fname."<br/>";
echo $lname;
}
echo var_dump($_POST);
?>
最佳答案
我用这样的东西：
// Your http url
NSURL* url = @"<your web url>";
AFHTTPClient* client = [[AFHTTPClient alloc]initWithBaseURL:url];
// create request
NSMutableURLRequest *request=[NSMutableURLRequest
requestWithURL:[NSURL URLWithString:strUrl]
cachePolicy: NSURLRequestReloadIgnoringLocalCacheData
timeoutInterval:60.f];
// set http method as POST
[request setHTTPMethod:@"POST"];
// TODO: set your params for post, convert them to post data and set to requesr
// NSMutableDictionary* authParams = @{ "param1" : @"val1", @"param2" : @"val2"}
// [request setHTTPBody:postData]
// sample file upload combined with post action
request = [client multipartFormRequestWithBaseRequest:request parameters:authParams constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
// Important!! : file path MUST BE real file path (so -> "file://localhost/.../../file.txt") so i use [NSURL fileURLWithPath:]
NSError* err;
[formData appendPartWithFileURL:[NSURL fileURLWithPath:filePathToUpload] name:[fileInfo objectForKey:@"fileName"] error:&err];
}];
AFHTTPRequestOperation *operationX = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operationX setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
// call to external completion block
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
// call to external failure block
}];
// run operation
[yourOperationQueue addOperation:operationX];
// =============
//implementing in AFHTTPClient ( for upload case , to reuse you own request)
- (NSMutableURLRequest *)multipartFormRequestWithBaseRequest:(NSMutableURLRequest*)request
parameters:(NSDictionary *)parameters
constructingBodyWithBlock:(void (^)(id <AFMultipartFormData> formData))block
{
__block AFStreamingMultipartFormData *formData = [[AFStreamingMultipartFormData alloc] initWithURLRequest:request stringEncoding:self.stringEncoding];
if (parameters) {
for (AFQueryStringPair *pair in AFQueryStringPairsFromDictionary(parameters)) {
NSData *data = nil;
if ([pair.value isKindOfClass:[NSData class]]) {
data = pair.value;
} else if ([pair.value isEqual:[NSNull null]]) {
data = [NSData data];
} else {
data = [[pair.value description] dataUsingEncoding:self.stringEncoding];
}
if (data) {
[formData appendPartWithFormData:data name:[pair.field description]];
}
}
}
if (block) {
block(formData);
}
return [formData requestByFinalizingMultipartFormData];
